Tips: Signal relay troubleshooting

In the process of circuit application, improper operation or other interference factors will lead to signal relay faults. Common faults of signal relays include fuse fusing, wire breaking, sealing-off, screw loosening, coil burnout, bad contact of contacts, bad contact of connectors, bad insulation between lines and mixed power supply of lines. The solutions of the signal relay faults are as follows.

  • Mixed line protection circuit
    Indoor and signal relay box environment is better, as long as strict construction technology is adopted, mixed line fault rarely occurs in the circuit, so it is no need to take mixed line protection measures. For the outdoor circuit, whether the cables or other wires are used as the connecting line, the possibility of mixed line failure is more likely to occur, and the mixed line protection circuit needs to be adopted.
  • Disconnection protection circuit
    Disconnection fault is far more than mixed fault. The closed circuit method is used to design the signal relay circuit in order to drop the signal relay to protect the circuit in the event of a disconnection fault.

I wish I would have done this signal relay a lot earlier.
I cant believe this signal relay worked and now everything is working as it should. I tried other signal relays but none of them worked. I wish I would have done this signal relay a lot earlier.
