4-1 Selecting hardware on output side

Output is NPN open collector output.
PCB internal circuit
+24V
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
+24V
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.
