Coil Ratings

Rated voltage		Rated current	Coil resistance	Must-operate voltage	Must-release voltage	Max. voltage	Power consumption
AC	24 VAC	75 mA	---	75% max. of rated voltage	15% min. of rated voltage	110% of rated voltage	Approx. 1.8 to 2.6 VA
	50 VAC	36 mA	---
	100 to 120 VAC	18 to 21.6 mA	---
	200 to 240 VDC	9 to 10.8 mA	---
DC	12 VDC	167 mA	72 Ω		10% min. of rated voltage		Approx. 2.0 W
	24 VDC	83 mA	288 Ω
	48 VDC	42 mA	1,150 Ω
	100 VDC	20 mA	5,000 Ω

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/-20%
for AC rated current and ±15% for DC coil resistance. (The values given for AC rated current apply at 50 Hz or
60 Hz.)
2. Performance characteristic data are measured at a coil temperature of 23°C.
3. The maximum voltage is one that is applicable to the Relay coil at 23°C.

*1. The above values are all initial values.
*2. The contact resistance was measured with 1 A at 5 VDC using the voltage drop method.
*3. The operate and the release times were measured with the rated voltage imposed with any contact bounce ignored
at an ambient temperature of 23°C.
*4. The insulation resistance was measured with a 500-VDC megger applied to the same places as those used for
checking the dielectric strength.
*5. The electrical endurance was measured at an ambient temperature of 23°C.
*6. This value was measured at a switching frequency of 60 operations per minute.
