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.
