Universal Input/Output (HART)

FB7204B3

analog output, digital output

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 intrinsically safe signals are galvanically isolated from the bus and the power supply.
