Relay FAQ
The relay is not conducting
1) When the relay should be turned on, measure the input voltage. If the voltage is lower than the required operating voltage, it indicates that there is a problem with the line in front of the SSR input; if the input voltage is higher than the required operating voltage, check the polarity of the power supply and if necessary be corrected.
2) Measure the input current of the SSR. If there is no current, it means that the SSR is open, and the relay is faulty; if there is current, but it is lower than the action value of the relay, there is a problem with the line in front of the SSR and must be corrected.
3) Check the input part of the SSR, measure the voltage across the output of the SSR, if the voltage is lower than 1V, it indicates that the line or load other than the relay is open and should be repaired; if there is a line voltage, it may be the load short circuit, causing the current to be too large. Relay failed.
