4-1 Selecting hardware on output side
Output is NPN open collector output.
PCB internal circuit
On the assumption that output activates the air valve (option part).
Use a 24 VDC relay if not using a 24 V air valve.
PCB internal circuit External 24V relay
No fuses are built in the output circuit. To prevent circuit damage when forming short output, it is
recommendable to install an external fuse on each output.
4-2 Selecting hardware on input side
Input is non-insulating IC input.
PCB internal circuit Example of connection with proximity sensor
Insulate input using a relay if not using a contact switch or a 24 V sensor.
PCB internal circuit External relay
Use a relay for electronic circuit whose maximum applicable load is 5 V and 1m A or less.
