The output transistor turns off when a load short-circuit or overload occurs. Check the load state before restarting.
Connection for single set use

- Use a relay suitable for the power supply and the output rating.
Also, use a surge suppressor diode.
- The output transistor turns off when a load short-circuit or overload occurs. Check the load state before restarting.
- The black and purple lines of the transmitter are not connected.
The lines need insulating so that they will not touch other lines.
Connection for mutual interference prevention

- Use a relay suitable for the power supply and the output rating.
Also, use a surge suppressor diode.
- The output transistor turns off when a load short-circuit or overload occurs. Check the load state before restarting.
- When using two power supplies, share a common OV.
