Aiphone Corporation RY-24L Form-C Door Release Relay for AX, JM , JO, or KB Series, ABS Plastic Construction

The RY-24L Door Release Relay Module is an interface between the door release contact on the Aiphone monitor and the actual release mechanism. The contact closure directly out of the monitor is rated at 12V AC with a low current capacity. If your strike or maglock requires more voltage or current, the RY-24L is required. It provides either a Normally Open contact for an electric strike, or a Normally Closed contact for a magnetic lock. The contact rating supports a majority of door release hardware available on the market. The RY-24L relay is recommended with all AX, KB, KC and JP video systems when using the door release feature. This will protect the built-in contact from possible surge damage.
