HC

(2) DC coils

Notes: 1. The coil resistance for DC operation is the value measured when the coil temperature is 20

2. The relay operates in a range of 80% to 110% V of the voltage rating, but ideally, in consideration of temporary voltage fluctuations, it should be operated at the

rated voltage.

3. For use with 200 V DC, connect a 10 K

Ω (5W) resistor, in series, to the 100 V DC relay.

4. The maximum applied voltage is the maximum voltage fluctuation value for the coil power supply. This value is not a permissible value for continuous operation.

(This value differs depending on the ambient temperature. Please contact us for details.)

2) Specifications

Notes: *1. This value can change due to the switching frequency, environmental conditions and desired reliability level, therefore it is recommended to check this with the

actual load.

*2. For the AC coil types, the operate/release time will differ depending on the phase.

*3. The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage

conditions in NOTES.
