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. The AC coil resistance and coil inductance values are for reference only.
           3. Performance characteristic data is measured at a coil temperature of 23°C.
           4. The maximum voltage is one that is applicable instantaneously to the Relay coil at 23°C and not continuously.
           5. For built-in operation indicator models rated at 6, 12, and 24 VDC, add an LED current of approx. 5 mA to the
                rated currents.

Note: 1. The data shown above are initial values.
           2. The contact resistance was measured with 0.1 A at 5 VDC using the voltage drop method.
           3. The operate and release times were measured with the rated voltage imposed with any contact bounce ignored
                 at an ambient temperature of 23°C.
           4. The insulation resistance was measured with a 500-VDC megger applied to the same places as those used for
                checking the dielectric strength.
           5. This value was measured at a switching frequency of 60 operations per minute.
           6. The electrical endurance was measured at an ambient temperature of 23°C.
