Pulse relay

Thread Content

The pulse relays on the screen in the main power distribution control room keep burning out. What are the possible reasons?

Check whether the power supply voltage is too high (due to a mismatch between the designed and actual model), and whether interference is causing the voltage to be too high.

Agree with what was said above; maybe the wires are connected incorrectly. Check this wiring path from start to finish~`

Is it the relay coil that’s burned out? Or has the relay itself been completely damaged...?
