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 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.

| Applied coil voltage | Coil resistance∗ | Power consumption | |
|---|---|---|---|
| Rated voltage | 100% | 125Ω (5 VDC) 720Ω (12 VDC) 2880Ω (24 VDC) |
Approx. 200 mW |
| Holding voltage | 40% | Approx. 32 mW |
Power consumption reduction of coil with pulse width modulation (PWM)
- 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.
- The following are our verification conditions. When using, it be sure to check the actual machine under the actual usage conditions.
■Example of drive circuit
■Conditions of validation carried out by OMRON
- Applied voltage: rated voltage
- Duty: 50% or more
- Frequency: 10 kHz or more
- Diode Vf: 0.4 V or less
