The freely programmable Saia PCD2.M4 controllers are ideal both for small and large-scale applications, e.g. in machine control and building or infrastructure automation. Thanks to their generous memory resources and ample CPU power, they can cope with even demanding communication tasks.
The base device has 4 slots for I/O modules. By connecting Saia PCD2.C1000 or Saia PCD2.C2000 module holders, you can expand the Saia PCD2.M4 controllers in a modular manner to up to 1023 digital inputs/outputs.
