1 Introduction
The MINI and MIX series of I/O modules with RS485 and IP (2 Ethernet) have
been designed for building distributed control systems using MAC36, AAC20, or
another controller. Each module is equipped with the most commonly used types
of I/O in building automation. Depending on the version, the device has 18 or
38 inputs and outputs, a mix of all types of I/O in one unit. All I/O modules
have BTL and UL certificates. The modules with RS485 and IP (2 Ethernet) are
factory-equipped with the two most popular open communication protocols:
Modbus (ASCII, RTU, TCP/IP) and BACnet (MS/TP, IP), which are selected using
DIP switches. Rotary switches are used to set the module address, which
facilitates and accelerates the process of commissioning the system. Builtin
mini USB allows for the initial configuration of the unit without external
power supply. Built-in Modbus Gateway TCP/IP to Modbus ASCII/RTU enables to
connect additional modules/devices that communicate via Modbus RS485. Thanks
to supporting open communication standards I/O modules can be installed in
both new and completed installations, as part of existing BMS. This versatile
device will fit any BMS perfectly.

This user manual outlines all information specific to using I/O modules in the
Modbus protocol.

2 Safety Rules
· Improper wiring of the product can damage it and lead to other hazards. Make
sure that the product has been correctly wired before turning the power on.
· Before wiring or removing/mounting the product, make sure to turn the power
off. Failure to do so might cause an electric shock.
· Do not touch electrically charged parts such as power terminals. Doing so
might cause an electric shock.
· Do not disassemble the product. Doing so might cause an electric shock or
faulty operation.
· Use the product only within the operating ranges recommended in the
specification (temperature, humidity, voltage, shock, mounting direction,
atmosphere, etc.). Failure to do so might cause a fire or faulty operation.
· Firmly tighten the wires to the terminal. Failure to do so might cause a
fire. · Avoid installing the product in close proximity to high-power
electrical devices and
cables, inductive loads, and switching devices. Proximity of such objects may
cause an uncontrolled interference, resulting in an instable operation of the
product. · Proper arrangement of the power and signal cabling affects the
operation of the entire control system. Avoid laying the power and signal
wiring in parallel cable trays. It can cause interferences in monitored and
control signals. · It is recommended to power controllers/modules with AC/DC
power suppliers. They provide better and more stable insulation for devices
compared to AC/AC transformer systems, which transmit disturbances and
transient phenomena like surges and bursts to devices. They also isolate
products from inductive phenomena from other transformers and loads. · Power
supply systems for the product should be protected by external devices
limiting overvoltage and effects of lightning discharges. · Avoid powering the
product and its controlled/monitored devices, especially high power and
inductive loads, from a single power source. Powering devices from a single
power source causes a risk of introducing disturbances from the loads to the
control devices. · If an AC/AC transformer is used to supply control devices,
it is strongly recommended to use a maximum 100 VA Class 2 transformer to
avoid unwanted inductive effects, which are dangerous for devices. · Long
monitoring and control lines may cause loops in connection with the shared
power supply, causing disturbances in the operation of devices, including
external communication. It is recommended to use galvanic separators. · To
protect signal and communication lines against external electromagnetic
interferences, use properly grounded shielded cables and ferrite beads. ·
Switching the digital output relays of large (exceeding specification)
inductive loads can cause interference pulses to the electronics installed
inside the product. Therefore, it is recommended to use external
relays/contactors, etc. to switch such loads. The use of controllers with
triac outputs also limits similar overvoltage phenomena. · Many cases of
disturbances and overvoltage in control systems are generated by switched,
inductive loads supplied by alternating mains voltage (AC 120/230 V). If they
do not have appropriate built-in noise reduction circuits, it is recommended
to use external circuits such as snubbers, varistors, or protection diodes to
limit these effects.

2.1 Wiring
In most cases, I/O modules will be installed in an enclosure along with the
other devices, which generate electromagnetic radiation. Relays, contactors,
transformers, motor invertors, etc., are examples of such devices. Radiation
can induce electrical noise into both power and signal lines, as well as
direct radiation into the module. Whether or not the iSMA modules are immune
to such effects, the interferences must be suppressed at their source if
possible to ensure the proper functioning of the entire system. Appropriate
grounding, shielding and other protective steps should be taken at the
installation stage to prevent these effects. It is recommended to at least
follow the rules below:
· Line power cables must be routed with spatial separation from signal and
data transmission cables.
· Analog and digital signal cables should also be separated. · It is
recommended to use shielded cables for analog signals, cable shields should
not
be interrupted by intermediate terminals. · The shielding should be earthed
directly after the cable enters the cabinet.
It is recommended to install interference suppressors when switching inductive
loads (e.g., coils of contactors, relays, solenoid valves). RC snubbers or
varistors are suitable for AC voltage and freewheeling diodes for DC voltage
loads. The suppressing elements must be connected as close to the coil as
possible.
2.2 EN 60730-1 Power Supply Considerations
· Electrical safety in the building automation and control systems is
essentially based on the use of extra-low voltage which is strictly separated
from the mains voltage. This low voltage is either SELV or PELV according to
EN 60730-1.
· Protection against electric shock is ensured by the following measures:
Limitation of voltage (low voltage AC/DC 24V supply, either SELV or PELV)
Protective-separation of the SELV-system from all circuits other than SELV and
PELV Simple-separation of the SELV-system from other SELV-systems, from
PELVsystems and earth
· Field devices such as sensors, status contacts, and actuators connected to
the lowvoltage inputs and outputs of I/O modules must comply with the
requirements for SELV or PELV. The interfaces of field devices and other
systems must also satisfy SELV or PELV requirements.
· If the supply of SELV or PELV circuits is obtained from supply mains of
higher voltages, it shall be provided by safety transformer or a converter
designed for continuous operation to supply SELV or PELV circuits.
2.3 FCC Compliance Note
Note: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio

particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
· Reorient or relocate the receiving antenna; · Increase the separation
between the equipment and receiver; · Connect the equipment into an outlet on
a circuit different from that to which the
receiver is connected; · Consult the dealer or an experienced radio/TV
technician for help.

4.4 RS485 Port 4.4.1 RS485 Communication Bus Connection
Figure 25. RS485 connection
4.4.2 RS485 Network Termination
Transmission line effects often present problems for data communication
networks. These problems include reflections and signal attenuation. To
eliminate the presence of reflections of signal from the end of the cable, the
cable must be terminated at both ends with a resistor across the line adequate
to its characteristic impedance. Both ends must be terminated since the
propagation is bidirectional. In case of an RS485 twisted pair cable this
termination is typically 120 .
4.5 Setting Module Address
To determine the address on the Modbus network, the module is equipped with
two rotary switches, S1 and S2, located on the top panel of the device. It is
possible to set the device address from 0 to 99. The address is set with the
following formula: Address = S2 · 10 + S1 where S1 and S2 are the values of
the switches. For example:

· resistance and temperature measurement (10k thermistor, a full list of
supported temperature sensors is available here: List of Supported Temperature
Sensors);
· dry contact (output current 1 mA).
Current measurement is realized by voltage measurement and 200 resistance.
According to Ohm’s law, the current is directly proportional to the voltage,
and the resistance is the constant of proportionality. (I = U / R). According
to the Ohm’s law equation, for 20 mA current with 200 resistance the output
voltage is 4 V. It means that the 4 V voltage measured on the universal input
corresponds to 20 mA current. The result is expressed in millivolts.

7.1.6 Filter Time Constant of the Universal Input 1-8 (40159-40166)
These 16-bit registers contain a time constant low pass filter. The value is
expressed in seconds. Valid values must be between 0 and 60 seconds. The
default filter value is 2 seconds. Setting the value to 0 disables the filter.
In case of the UI shortcut or open-loop, the filter is reset and the UI value
filtering is stopped.
7.1.7 Resolution of the Universal Inputs (40167)
This register is used to determine the bit resolution for each of the
universal inputs.
Setting the bit to 0 sets the resolution of the converter to 12-bit. Setting
the bit to 1 sets the resolution of the converter to 16-bit.
WARNING!
Setting 16-bit resolution increases the measurement time of one channel from
10 ms to 140 ms. The total time taken to measure all the channels increases
from 50 ms to 700 ms.

Table 35. Special application modes
The operating mode can be changed by writing the right value in the Operation Mode register.
Special modes are initialized after 3 seconds from the power-up or restart of the module (the time value needed to stabilize the operation of the analog transmitter).
With each change of the input mode, the assigned output is set to default state and the timer used in time-based modes is reset. If the recently selected operating mode is running, the output is controlled according to the new mode activated.
Ordinary IO
In this mode, the module operates as a standard IO; the inputs and the outputs
are in no relation with each other.
Monostable Relay
In this mode, both the rising and the falling edge of the digital input change
the output state. The action of a monostable relay can be executed remotely by
changing the state of bit from false to true in the COMMAND register (40020).
Outputs can by also overwritten with the DIGITAL OUTPUT register (40018),
which allows remote control from BMS.
Bistable Relay
In this mode, only the rising edge of the digital input changes the output
state. The action of a bistable relay can be executed remotely by changing the
state of bit from false to true in the COMMAND register (40020). Outputs can
be also overwritten by the DIGITAL OUTPUT register (40018 ), which allows
remote control from BMS.
Time Relay NO [ms] In this mode, if the output value is false, the rising edge of the digital input sets the output to a true value. Every falling edge of the digital input starts the counter from the beginning so that the output stays in a true value for the time defined in the TIME VALUE register (expressed in milliseconds), counting from the last falling edge of the digital input. The action of the time relay can be executed remotely by changing the state from false to true in the relevant COMMAND register (40020). The outputs can be also overwritten with the register of the DIGITAL OUTPUT module (40018), which allows for remote control from BMS.

Time Relay NC [ms] In this mode, if the output value is false, the falling
edge of the digital input sets the output to a true value. Every rising edge
of the digital input starts the counter from the beginning so that the output
stays in true value for a time defined in the TIME VALUE register (expressed

Time Relay NO [s] In this mode, if the output value is false, the rising edge
of the digital input sets the output to a true value. Every falling edge on
the digital input starts the counter from the beginning so that the output
stays in true value for a time defined in TIME VALUE register (expressed in
seconds), counting from the last falling edge of the digital input. The action
of time relay can be executed remotely by changing the state from false to
true in relevant COMMAND register (40020). Outputs can be also overwritten
with the register of DIGITAL OUTPUT module (40018), which allows for remote
control from BMS.

the relevant COMMAND register (40020). Outputs can be also overwritten with
the register of DIGITAL OUTPUT module (40018), which allows for remote control

Input Forwarding
In this mode, any signal from the input is transferred directly to the
assigned output without any modifications. The operation of the input
forwarding mode can be stopped with the block input function.
Heating Mode (4U4O-H and 4U4O-H-IP Only)
In this mode, the output is controlled like a typical thermostat, based on the
Setpoint register and control value (input value) with differential parameter
defined in the Differential register. The output signal works in 2 states, low
and high.
If the control value is lower or equal with the difference between the
Setpoint register and the Differential register, the output is in the low
state.
If the control value is higher or equal with the sum of the Setpoint register
and the Differential register, the output is in the high state.
Output in the low state:
Control value >= Setpoint + Differential
Output in the high state:
Control value <= Setpoint Differential
