General Instructions
The unit can work as an independent element without the central unit only
within a very limited scope of its functions. For full utilizability of the
unit, it is necessary that the unit is connected to a central unit of a CU3
series system or to a system that includes such a unit as an extension of
other system functions. All parameters of the unit can be set through the CU3
series unit in the iDM3 software.
Connection and Installation
For supplying power to system units, it is recommended to use the power
source of ELKO EP titled PS3-100/iNELS or PS3-100/iNELS. We recommend backing
up the system with backup batteries connected to the source of PS3-100/iNELS
(see sample diagram of connecting the control system).
Characteristics
- IOU3-108M is an input/output actuator equipped with 8 binary inputs, 2 temperature inputs, and 8 independent relays with switching potential-free contacts.
- The IOU3-108M binary inputs are used for connection of up to 8 devices with potential-free contacts (such as switches, change-over switches, pushbuttons of another design, EZS [electronic safeguarding system] and EPS [electronic fi re alarm system] detectors, etc.).
- The unit can also be used for counting pulses from energy meters with pulse outputs.
- The temperature inputs support the connection of temperature TC/TZ sensors with 2-wire wiring.
- It is used in cases where it is necessary to monitor temperature, e.g. floor/room, interior/exterior temperature, technological equipment (boiler rooms, solar heating, etc.).
- The maximum loading capacity of the contacts is 10A/2500VA/AC1.
- The unit includes the function of switching of a relay at the alternating voltage zero value. The inputs for synchronization use the voltage 110-230V AC (COM 1,2,3,4) against the N terminal.
- Each of the output contacts can be controlled and addressed independently.
- The relays are divided into four pairs, where each pair switches its common potential.
- The actuator is designed for switching up to eight different appliances and loads using a relay output (potential-free contact).
- IOU3-108M in the 6-MODUL version is designed for installation in switchboard cabinets on DIN bars type EN60715.

General instructions
CONNECTION TO THE SYSTEM, INSTALLATION BUS
iNELS3 peripheral units are connected to the system through the BUS installation. Installation BUS conductors are connected to the terminal units to BUS+ and BUS- terminals, wires cannot be interchanged. For the installation of BUS, it is necessary to use a cable with a twisted pair of wires with a diameter of at least 0.8 mm, the recommended cable is iNELS BUS Cable, whose features best meet the requirements of the BUS installation. Bearing in mind that in terms of all the properties, it is possible in most cases to also use the cable JYSTY 1x2x0.8 or JYSTY 2x2x0.8, however, it is not recommended as the best option. In the case of a cable with two pairs of twisted wires, it is not possible to use the second pair of the other for modulated signal due to the speed of communications; it is not possible within one cable to use one pair for one segment BUS and the second pair for the second segment BUS.
For the installation of a BUS, it is vital to ensure that it is kept at a distance from the power lines of at least 30 cm and must be installed in accordance with its mechanical properties. To increase the mechanical resistance of cables we recommend installation into a conduit of suitable diameter. BUS topology installation is free except for the ring, wherein each end of the bus must terminate at the terminals BUS + and BUS- peripheral unit. While maintaining all the above requirements, the maximum length of one segment of the installation BUS can reach up to 500 m. Due to the data communication and supply of units in one pair of wires, it is necessary to keep in mind the diameter of wires with regard to voltage loss on the lead and the maximum current drawn. The maximum length of the BUS applies provided that they comply with the tolerance of the supply voltage.
CAPACITY AND CENTRAL UNIT
Central units type CU3-0xM are the main components of the iNELS busbar
installation. There are several types of central units; according to their use
and communication interfaces. Each central unit has at least one BUS bar. Up
to 32 units can be connected to this busbar. The total number of units and
busbars is given by the number of central units in the superordinated topology
of the iNELS BUS system. Further, it is necessary to follow the requirement
for maximum loading of one branch of the BUS bar by max. 1000mA current is
given by the sum of nominal currents of the units connected to this busbar
branch. In case of connection of units with withdrawal exceeding 1A, you can
use BPS3-01M with a withdrawal of 3A.
SUPPLYING THE SYSTEM
For supplying power to system units, it is recommended to use the power source
of ELKO EP titled PS3-100/iNELS or PS3-100/iNELS. We recommend backing up the
system with backup batteries connected to the source of PS3-100/iNELS (see
sample diagram of connecting the control system).
GENERAL INFORMATION
The unit can work as an independent element without the central unit only within a very limited scope of its functions. For full utilizability of the unit, it is necessary that the unit is connected to a central unit of a CU3 series system or to a system that includes such unit as an extension of other system functions. All parameters of the unit can be set through the CU3 series unit in the iDM3 software. On the front panel of the unit, you can find some LED diodes for indication of power supply voltage and communication with the CU3 series central unit. In case the diode RUN fl ashes in regular intervals, standard communication runs. In case the diode RUN is permanently on, the unit is supplied from the busbar, however, it does not communicate on the busbar. In case the diode RUN is off, no voltage is present on the BUS+ and BUS- terminals.
Warning
Before the device is installed and operated, read this instruction manual
carefully and with full understanding and Installation Guide System iNELS3.
The instruction manual is designated for mounting the device and for the user
of such device. It has to be attached to the electro-installation
documentation. The instruction manual can be also found on the website
www.inels.com. Attention, danger of injury by
electrical current! Mounting and connection can be done only by a professional
with an adequate electrical qualifi cation, and all has to be done while
observing valid regulations. Do not touch parts of the device that are
energized. Danger of life-threat! While mounting, servicing, executing any
changes, and repairing it is essential to observe safety regulations, norms,
directives, and special regulations for working with electrical equipment.
Before you start working with the device, it is essential to have all wires,
connected parts, and terminals de-energized. This instruction manual contains
only general directions that need to be applied in a particular installation.
In the course of inspections and maintenance, always check (while de-
energized) if terminals are tightened. e-mail:
