Cautions For Use

HE-N Relays Cautions for Use

For cautions for use, please read “Relays Cautions for Use”.

Condition for use, storage and transportation

1.Ambient temperature：
-40～+55°C (When coil holding voltage is 40 to 100%V of rated voltage.)
-40～+85°C (When coil holding voltage is 50 to 60%V of rated voltage or storage.)
2.Humidity：5～85%RH
(Avoid icing when using at temperatures lower than 0°C.)

Note: In addition the humidity range depends on temperature.The allowable ranges are as shown in the figure.

Temperature and humidity range for usage, storage and transport

［Coil holding voltage 40～100%V］

［Coil holding voltage 50～60％V］

Coil surge absorber

Please use a Varistor (ZNR) or Zener diode (ZD) which the clamp voltage is at least 3 times larger than the rated voltage for the purpose of the coil surge absorber.
If the clamp voltage is less than 3 times larger than the rated voltage, electrical life of the relay specified in the specifications shall not be secured because the contact release speed becomes slower.

[Example 1: When Varistor (ZNR) is use]

Recommended Varistor	Energy capability: Min. 1 J (However, please set up the value with consideration of the worst value in use condition.)
Varistor Voltage	Min. 300% of rated voltage (Recommended Varistor voltage is at 36 V or more when the coil rated voltage is at 12 V.)

[Example 2: When Zener diode (circuit) is use]
(Set the clamp voltage at 36 V or more when the coil 1 rated voltage is at 12 V.)
