TECHNICAL SPECIFICATIONS
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 centre authorized to recycle electrical and electronic waste.
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

Note:
When DIP switches 1 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.

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).
For maximum performance, it is recommended to use special shielded cables, such as BELDEN 9841.
| Bus length | Derivation length |
|---|---|
| 1200 m | 2 m |
INSTALLATION REGULATIONS
The module has been designed for vertical installation on a DIN 46277 rail.
For optimal operation and long life, adequate ventilation must be provided.
Avoid positioning ducting or other objects that obstruct the ventilation
slots. Avoid mounting modules over heat-generating equipment. Installation in
the bottom part of the electrical panel is recommended.
Insertion in the DIN rail As shown in figure:
- Insert the IDC10 rear connector of the module on a free slot of the DIN rail (the insertion is univocal since the connectors are polarized).
- To secure the module to the DIN rail, tighten the two hooks on the sides of the IDC10 rear connector.
Power supply and Modbus interface are available using the Seneca DIN rail bus,
via the IDC10 rear connector, or the Z-PC-DINAL-17.5 accessory.
USB
PORT
The module is designed to exchange data according to the modes defined by the
MODBUS protocol. It has a micro USB connector and can be configured using
applications and/or software programs. The USB serial port uses the following
communication parameters: 115200,8,N,1 The USB communication port responds
exactly like the RS485 or RS232 ports with the exception of the communication
parameters. EASY SETUP is the software to use for the configuration. For

- Check that the device in question is included in the list of products supported by the Easy Setup APP in the store. Check that the device in question is included in the list of products supported by the Easy Setup APP in the store.
ELECTRICAL CONNECTIONS
Attention:
the upper power supply limits must not be exceeded, as this might cause
serious damage to the module.
To meet the electromagnetic immunity requirements:
- use shielded signal cables;
- connect the shield to a preferential instrumentation earth system;
- separate shielded cables from other cables used for power installations (transformers, inverters, motors, induction ovens, etc…).
