Ratings
Coil
| Rated voltage | Rated current (mA) | Coil resistance ( Ω ) | Must operate voltage (V) | Must release voltage (V) | Max. voltage (V) | Power consumption (mW) |
| 24 VDC | 4 poles: 15 6 poles: 20.8 | 4 poles: 1,600 6 poles: 1,152 | 75% max. | 10% min. | 110% | 4 poles: Approx. 360 6 poles: Approx. 500 |
Note:
1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of ±15%.
2. Performance characteristics are based on a coil temperature of 23°C.
3. The value given for the maximum voltage is for voltages applied Instantaneously to the Relay coil (at an ambient temperature of 23°C) and not continuously.

Note: The above values are initial values.
*1.The contact resistance was measured with 1 A at 5 VDC using the voltage-drop method.
*2.These times were measured at the rated voltage and an ambient temperature of 23°C. Contact bounce time is not included.
*3.The response time is the time it takes for the normally open contacts to open after the coil voltage is turned OFF. Contact bounce time is included. Measurement conditions: Rated voltage operation, Ambient temperature: 23°C
*4.The insulation resistance was measured with a 500-VDC megohmmeter at the same locations as the dielectric strength was measured.
*5.Pole 3 refers to terminals 33−34, pole 4 refers to terminals 43−44, pole 5 refers to terminals 53−54, and pole 6 refers to terminals 63−64.
*6.The durability is for an ambient temperature of 15 to 35°C and an ambient humidity of 25% to 75%.
*7.The failure rate is based on an operating frequency of 300 operations/min.
*8.When operating at a temperature between 70 and 85°C, reduce the rated carry current (6 A at 70°C or less) by 0.1 A for each degree above 70°C.
Caution: In the interenst of product improvement, specifications are subject to change without notice.
