Aiphone RY-1824L - control relay

The RY-1824L door release relay module is an interface between the door release contact on the Aiphone master station or CEU and the actual release mechanism. The contact closure directly from the master station or CEU has limited voltage and current capacity. Use the RY-1824L to ensure that the contact rating will be sufficient for the electric strike or magnetic lock used. The relay's contact rating supports a majority of door release hardware available.
