COIL DATA
Note: 1. The rated current and coil resistance are measured at a coil temperature of 23 C (73 F) with a tolerance of 15% for DC
rated current and +15%, -20% for AC rated current.
2. The rated current is reference value.
3. Performance characteristic data are measured at a coil temperature of 23 C (73 F).
4. For models with the LED indicator built-in, add an LED current of approximately 0 thru 5 mA to the rated current.
