20 series Power Relays Apply rated voltage to the relay coil to ensure correct relay type. When using a power supply containing a ripple voltage, suppress the ripple factor within 6% however, a complete DC voltage is best for the coil power to make sure of stable relay operation. Pickup voltage and dropout voltage depend on the ripple factor when power is supplied through a rectification circuit. Include a smoothing capacitor for better E max = Maximum of pulsating current Emin = Minimum of pulsating current Emean= DC mean value Special consideration should be taken when driving an element at...

20 series Power Relays Do not drop, shock or remove the relay cover to maintain the initial characteristics. The relay cover cannot be removed from the base during normal operation. Use the relay in environments free from dust, condensation, dioxide or hydrogen sulfide. Make sure that the coil voltage does not exceed applicable coil voltage range. Prevent usage of relays in the vicinity of strong magnetic field, as that my cause in malfunctioning of relays. Failure to turn off power before wiring, installation, removal and maintenance may cause electrical shock or fire hazard. Attention on specifications...
