Specifications ■ Coil Ratings Open Coils (with Solder or Screw Terminals) Rated voltage (V) Mustrelease voltage Mustoperate voltage 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 values are reference values. 3. Performance characteristic data are measured at a coil temperature of 23°C. 4. The maximum voltage is one that is applicable instantaneously to the Relay coil at an ambient temperature of 23°C and not continuously. Cased Coils...
