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.
2.
Performance characteristic data are measured at a coil temperature of 23°C.
3.
~
indicates AC and
=
indicates DC (IEC417 publications).
4.
For 200 VDC applications, a 100-VDC Relay is supplied with a fixed 6.8 kΩ, 30 W resistor. Be sure to connect the resistor in series with
the coil.
5.
For models with the LED indicator built in, add an LED current of approximately 0 through 5 mA to the rated current.
