Correct Use
Mounting Direction
• Coils have polarity, so put diodes as it becomes reserve • This relay has limitation for mounting direction due to the specification direction with applied voltage for coils. of Operate voltage and Electrical durability. • The recommended Zener diode voltage is 3 times that of the Do not use in any other direction except as indicated in below chart. rated coil voltage. There is a risk of reduced operational lifetime for failure to observe • Use diodes whose reverse dielectric strength are 10 times or this warning. more that of coil rated voltage, and with forward current more Upper side than coil rated current. Contact terminal Diode Coil terminal Relay coil Zenner diode
PCB Terminal soldering
• Solder at 290°C for 20 seconds (max.) in soldering bath. • It is not possible to wash relay as this is not fully sealed type.
Assembly
• To reduce the risk of specification deterioration assemble relays in a dust free, low humidity and non-corrosive gas G 7

Operation
• Take care when mounting relays to utilize adequate B • Use this relay with coil voltage reduction. anchorage on both sides of PCB to optimize heat transfer and • Apply the rated voltage for 0.1 to 3 seconds to the coil first. reduce risk for both heat and mechanical stress. • The range of coil rated voltage must be set as 100 to 120%, • This product weight is about 100 g. Be careful of the strength holding voltage must be 45 to 65%. Do not exceed the ranges of PCB. And to reduce the happening of soldering crack due to due to the change of coil voltage change and so on. heat stress, use both sides through hole PCB. 100 to 120%
Drop
(Rated voltage) • Do not use relays in the event of any droppage.
Electrical Endurance
45 to 65% (Holding voltage) • As this relay is an AC high voltage type, there are increased risks of abnormal heat generation or fire if you use in a 0.1 to 3 seconds application inconsistent with published specification. Use only Applied coil Coil for AC load and within specified rating. Coil power consumption voltage resistance * • This relay's electrical endurance specification is based on our Rated voltage 100 to 120% Approx. 2.8 to 4.0 mW 51 Ω company standard test procedure with resistive loads. Relays Holding voltage 45 to 65% Approx. 0.57 to 1.2 mW intended for use with different; types of drive circuits PWM, * The coil resistances were measured at a coil temperature of 23°C with capacitive, resistive dropper etc.), types of loads (e.g. tolerances of ± 10%.
