TRP-C68M isolated 8-Ch analog input module

This device allows to acquire 8 analog inputs through an RS485 network, using ASCII or Modbus RTU protocol.
It is equipped with galvanic isolation up to 3750Vrms between the inputs and the RS485 interface, and can be used on network segments with up to 1200mt extension and up to 32 devices.The device is equipped with extractable terminals both for the connection of the RS485 I/F and the power supply and inputs.
The inputs are galvanically isolated from the system.

The extended range power supply from 10 to 30Vdc can be supplied either through removable terminals or through standard 12Vdc adapter (2.1mm jack).
