Precautions  

●

Please refer to “PCB Relays Common Precautions” for correct use.  

Correct Use  

●

Coil Voltage Reduction (Holding Voltage) after Relay  

Operation  

●

Power consumption reduction of coil with pulse width  

modulation (PWM)  

• 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.  

• Models

 

with PWM drive capability (-PW) can reduce coil  

holding current with PWM control. This function reduces power  

consumption by reducing the current held by coil.  

• Apply the rated voltage for at least 100 ms at the time of relay  

operation.  

• A voltage of at least 40% 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.  

• The following are our verification conditions. When using, it be  

sure to check the actual machine under the actual usage  

conditions.
