The change in contact resistance was measured after
leaving the Relay in the above environment for a fixed
amount of time, then removing it to a constant-temperature

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.
