Configurable, 4 channel, universal input/output modules.
Each channel can operate in the following modes:
- Analog input (AI) feeds 2-wire transmitters
- Analog output (AO) can drive proportional valves, I/P converters, or local indicators
- Digital input (DI) reads dry contacts
- Digital output (DO) can drive solenoids, sounders, or LEDs
A combination of analog and digital I/O is possible.
