overview
■ Application
-Used for lighting delay control in corridors, hallways, halls, and bathrooms.
■ Characteristics
-There are three working modes:
ON: The output contact remains in the ON state at all times
AUTO: Automatic delay control
OFF: The output contact remains in the OFF state at all times
-L-3 can be equipped with a neon light switch.
-The delay range can be set from 0.5 to 20 minutes (knob setting).
-The working status of the relay is indicated by LED indicator lights.
-Ultra small size, only 18mm width, 35mm card rail installation.
