Note • Rated current and coil resistance were measured at a coil temperature of 23°C with coil resistance of ±15%.
- Operating characteristics were measured at a coil temperature of 23°C.
- The maximum allowable voltage is the maximum value of the fluctuation range for the Relay coil operating power supply and was measured at an ambient temperature of 23°C.
