Safety Precautions
• For models with built-in operation indicators, check the coil polarity when
wiring and wire all connections correctly (DC operation).
• Use only combinations of OMRON Relays and Sockets.
Relay Replacement
To replace the Relay, turn OFF the power supply to the load and Relay coil
sides to prevent unintended operation and possible electrical shock.
Note: 1. An AC model has coil disconnection self-
diagnosis.
2. For the DC models, check the coil polarity
when wiring and wire all connections
correctly.

Coil Rating
Note: 1. The rated current for AC is the value measured with a DC ammeter in half-wave rectification.
2. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/−20% for the AC rated current and ±15% for the
DC coil resistance.
3. The AC coil resistance is a reference value only.
4. Operating characteristics were measured at a coil temperature of 23°C.
5. The maximum voltage capacity was measured at an ambient temperature of 23°C.
Contact Ratings
* With no icing or condensation.
