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. The maximum voltage is one that is applicable instantaneously to the Relay coil at 23°C and not continuously.
          4. For DC-operated Relays with the LED indicator built-in, add an LED current of approx. 5 mA to the rated current.
