Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with a tolerance of +15%/–20% (AC rated current) or ±10% (DC coil resistance).
         2. LEDs are used for the built-in operation indicator. For models equipped with these indications, the VAC rated current must be increased by approximately 1 mA; the VDC rated current, by approximately 4 mA.

         3. Operating characteristics are measured at a coil temperature of 23°C.
