The universal inputs plus outputs gave this station a lot of flexibility. I/O include 4 analogue inputs, 4 digital inputs, 4 relay outputs plus optional
2 analogue outputs. Field programmable inputs included thermocouples, RTD Pt100, mA, mV & V, thermister.

Each input could be individually programmed and ranged for any span via on Bd links. The analogue inputs on the 2100-A4 could be expanded up to 64 using the 2100-M input Multiplexers. Outputs include 4 relays for control or alarm, plus an option for 2 analogue outputs of 4~20mA or 0~10Vdc.

The 2100-A4 contained 4 in built on/off controllers or alarms. The controller/alarm setpoint (SV) and other parameters were downloaded from the user friendly MicroScan software, Mimic package, and held in permanent memory on the 2100-A4.

Other controller parameters included, output switching differential, auto/manual and manual settings of output. The 4 controllers/alarms on the 2100-A4 operated unaffected by computer power downs or reboots etc.
