The built-in I/O Module is used to connect sensors such as piezo buttons, reflection light buttons with PNP 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 PNP transistor output and 2 magnetic valves
