Digital I/O Module I/O-44E

With the module up to 4 commands can be transferred to the BUS system and 4 signals can be output. The functions of the inputs and outputs are freely programmable.

Quick Facts

  1. 4 optocoupler inputs
  2. 4 transistor outputs PNP, 24V/1A
  3. Coupling of illuminated pushbuttons or magnetic valves
  4. For sanitary or climate control on site

The built-in I/O Module is used to connect illuminated pushbuttons or magnetic valves and buttons to the subnet. The module can be used to transfer 4 commands to the BUS system and output 4 signals. The buttons or magnetic valves are connected via 4-pole Molex connectors.

Example: (see wiring diagrams) 2 buttons with feedback signal and 2 buttons with 2 magnetic valves
