ELECTRICAL CONNECTIONS

CAUTION

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;

- separate shielded cables from other cables used for power installations (transformers, inverters, motors, etc...).

The device can only be powered by a power supply with a limited energy circuit 40Vdc / 28Vac max in output according 

to CAN/CSA-C22.2 No.61010-1-12 / UL Std.No.61010-1 (3rd Edition) chapter 6.3.1/6.3.2 and 9.4 or class 2 according to 

CSA 223/UL1310.

Use only copper or copper-coated aluminium or AL-CU or CU-AL conductors

These are open type devices intended for installation in a final casing/panel that offers mechanical protection and protection 

against the spread of fire.

POWER SUPPLY

RS485 SERIAL PORT

RS232 SERIAL PORT

The power supply source must be protected from

To obtain the configuration from the Flash memory, both SW1 

DIP switch selectors must be set to OFF
To reset the device to factory settings both SW1 DIP switches 

must be set to ON
To force the device’s IP address to the standard value of 

SENECA Ethernet products: 192.168.90.101

Reserved

The DIP-switch settings are read only at boot time. At each change, perform a restart.
SW1 DIP-SWITCH:

Through DIP-SWITCH-SW1 it is possible to set the polarization of the bus relative to the RS485 port:

DESCRIPTION

DIP 1

DIP 2

To polarize the bus on RS485, both SW1 DIP switch selectors 

must be set to ON
NOT to polarize the bus on RS485, both SW1 DIP switch 

selectors must be set to OFF
