PRELIMINARY WARNINGS
The word WARNING preceded by the symbol indicates conditions or actions
that put the user’s safety at risk.
The word ATTENTION preceded by the symbol indicates conditions or actions
that might damage the instrument or the connected equipment. The warranty
shall become null and void in the event of improper use or tampering with the
module or devices supplied by the manufacturer as necessary for its correct
operation, and if the instructions contained in this manual are not followed.
**| WARNING: The full content of this manual must be read before any
operation. The module must only be used by qualified electricians. Specific
documentation is available via QR-CODE shown on page 1.
---|---
| The module must be repaired and damaged parts replaced by the Manufacturer.
The product is sensitive to electrostatic discharges. Take appropriate
measures during any operation.
**| Electrical and electronic waste disposal (applicable in the European
Union and other countries with recycling). The symbol on the product or its
packaging shows the product must be surrendered to a collection center
authorized to recycle electrical and electronic waste.

| Input status inversion: | DISABLED |
| Digital filter | 3ms |

Modbus CONNECTION RULES
- Install the modules in the DIN rail (120 max)
- Connect the remote modules using cables of an appropriate length. The following table shows cable length data:
– Bus length: maximum length of the Modbus network according to the Baud Rate. This is the length of the cables that connect the two farthest modules (see Diagram 1).
– Derivation length: maximum length of a derivation 2 m (see Diagram 1).
Diagram 1
| Bus length | Derivation length |
|---|---|
| 1200 m | 2 m |
For maximum performance, it is recommended to use special shielded cables, such as BELDEN 9841.
IDC10 CONNECTOR
Power supply and Modbus interface are available using the Seneca DIN rail bus, via the IDC10 rear connector, or the Z-PC-DINAL2-17.5 accessory.
Rear Connector (IDC 10)
The meaning of the various pins on the IDC10 connector is shown in the figure
if you wish to supply signals directly via it.
SETTING THE DIP-SWITCHES
The position of the DIP-switches defines the Modbus communication parameters
of the module: Address and Baud Rate
The following table shows the values of the Baud Rate and the Address
according to the setting of the DIP switches:
DIP-Switch status
SW1 POSITION| BAUD
RATE| SW1 POSITION| ADDRESS| POSITION| TERMINATOR
1 2 3 4 5 6 7 8| 3 4 5 6 7 8| 10
————–| 9600| | #1| | Disabled
————| 19200| | #2| | Enabled
———–| 38400| •••••••| #…| |
———–| 57600| | #63|
——-| From
EEPROM| | From
EEPROM| |
Note: When DIP switches 3 to 8 are OFF, the communication settings are
taken from programming (EEPROM).
Note 2: The RS485 line must be terminated only at the ends of the
communication line.
The settings of the dip-switches must be compatible with the settings on the
registers.
The description of the registers is available in the USER MANUAL.
ELECTRICAL CONNECTIONS
Power supply:
The upper limits must not be exceeded in order to avoid serious damage to the
module.
If the power supply source is not protected against overload, a safety fuse
must be installed in the power supply line with a value suitable to what the
situation requires.
Modbus RS485
Connection for RS485 communication using the MODBUS master system as an
alternative to the Z-PC-DINx bus.
N.B.: The indication of the RS485 connection polarity is not standardized and
in some devices may be inverted.
INPUTS
INPUT SETTINGS:
Default settings:
Input #1: 0 – 100 Hz (16BIT)
Input #2: 0 – 100 Hz (16BIT)
Input #3: 0 – 100 Hz (16BIT)
Input #4: 0 – 100 Hz (16BIT)
Input #5: 0 – 100 Hz (16BIT)
Input #5 can be set as a totalizer:
Input #5: 0 – 10 kHz (32BIT)
ATTENTION
The upper power supply limits must not be exceeded, as this might cause serious damage to the module. Switch the module off before connecting inputs and outputs.
To meet the electromagnetic immunity requirements:
- use shielded signal cables;
- connect the shield to a preferential instrumentation earth system;
- a fuse with a MAX. rating of 0,5 A must be installed near the module.
- separate shielded cables from other cables used for power installations (inverters, motors, induction ovens, etc…).
- make sure that the module is not supplied with a supply voltage higher than that indicated in the technical specifications in order not to damage it.
