Aiphone Corporation RY-18L - Form C Door Release Relay 123- 18V DC Input

The RY-18L Door Release Relay Module is an interface between the door strike contacts on the Aiphone unit and the actual release mechanism. The contact ratings on Aiphone units vary and are all Normally Open. If your strike or maglock is a higher voltage or draws more current than specified for the unit the RY-18L 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. This relay is recommended with all MK and JF systems when using the single door release feature and for the LEM-1DL or LEF systems when connecting a maglock.
