G N B ■Precautions

  • Please refer to “PCB Relays Common Precautions” for 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. * The coil resistance were measured at a coil temperature of 23°C with tolerances of ± 10%.
  • 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 Correct Use 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 40% (Holding voltage) 100% (Rated voltage) 100ms min.
