Digital I/O Module I/O-22E-S-NPN

With the module up to 2 commands can be transferred to the BUS system and 2 commands can be issued.

Quick Facts

  • 2 optocoupler inputs
  • 2 transistor outputs NPN, 24V/1A
  • Connection of sensors such as piezo buttons and reflection light buttons

The built-in I/O Module is used to connect sensors such as piezo buttons, reflection light buttons with NPN transistor output or door contacts type lfm-electronics NG 5001 and magnetic valves to the subnet. The module can be used to transfer 2 commands to the BUS system and to issue 2 commands. The sensors or magnetic valves are connected by means of assembled cable connectors.

Example: (see Wiring Diagrams) 2 reflection light buttons with NPN transistor output and 2 magnetic valves
