The Domat Control System input and output modules provide standardized interfaces between the process and the control system. They are used for process controls and for data acquisition in metering systems as well. Standard modules (4/8 DO, 8/16 DI, 8 AI, 8 AO, counters), and compact modules with HVAC-optimized I/O mix are available. Communicative room controllers are also integrated at this system level.
