1-1-2 Integrated I/Os
The microPAC base unit can house up to 28 I/O ports:
6 AI 6 analogue inputs configurable for mA, V (terminals E1... E6, F1... F6);
2 AI 2 optional universal or high level isolated analogue inputs configurable for
(terminals E7... E10, F7... F10):
- Thermocouples (TC J, K, L ,N, R, S, T);
- RTD (PT100, PT1000);
- ±mA, ±V linear inputs;
- Potentiometers.
4 AO 4 optional high level analogue outputs (terminals E11... E14, F11... F14);
RS RUN/STOP program functionality (terminal A1);
8 DI General Purpose Digital Inputs (terminals A2... A5, B2... B5);
8 DO
Isolated General Purpose Digital Outputs (terminals A6... A9, B6... B9).
