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.
