Symbol

Function

The device is a configurable universal module. Each channel can operate in the following modes:

As an analog input (AI) it feeds 2-wire transmitters.
As an analog output (AO) it can drive proportional valves, I/P converters, or local indicators.
As a digital input (DI) it reads dry contacts.
As a digital output (DO) it can drive solenoids, sounders, or LED.

A combination of analog and digital I/O is possible.
Channel LEDs indicate the status of each channel. White LEDs indicate whether AI, AO, DI, DO are selected.
The signals are galvanically isolated from the bus and the power supply.
