2. The coil resistance for DC operation is the value measured when the coil temperature is 20°C
68°F.
Compensate
±0.4%
for every
±1°C
change in temperature.
3. 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. In particular, for AC operation, if the impressed voltage drops to 80% V or more below the rated voltage, humming will occur and a large current will
flow leading possibly to coil burnout.
4. For use with 200 V DC, connect a 6.7kΩ (10W) resistor, in series, to the 100 V DC relay [3 Form C type is .6.4kΩ (5W); 4 Form C type is .6.2kΩ (10W)].
5. As a general rule, only a pure DC voltage should be used for the coil drive.
However, a DC power supply that contains ripples has characteristics that differ from pure DC.
Therefore, please verify characteristics (operate voltage, release voltage, humming) using the actual circuit that will be used.

Rating
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 operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. Refer to 6. Conditions for operation,
transport and storage mentioned in AMBIENT ENVIRONMENT.

Note: Cautions at DC load use
When used under a DC load operating at high repetition rate with considerable arcing, corrosion of the contacts and/or the contact blades is likely to occur.
