Precautions
Please refer to “PCB Relays Common Precautions” for correct use.
Correct Use
Coil Voltage Reduction (Holding Voltage) after Relay Operation
- If the coil voltage is reduced to the holding voltage after Relay operation, first apply the rated voltage to the coil for at least 100 ms, as shown below.
- A voltage of at least 30% of the rated voltage is required for the coil holding voltage. Do not allow voltage fluctuations to cause the coil holding voltage to fall below this level.
