RY024AM 24VDC Specialty Relay Module
The Alpha Communications® RY024AM specialty relay modules are used for a variety of reasons. They are primarily used with room calling stations on the AlphaEcall™ 200 series emergency-call systems. It can also be used to provide a 'Form C' relay contact from virtually any 24VDC input source. The RY024AM can even be powered directly from a 24VDC power supply.

As long as a 24VDC source is present, the RY024AM will engage, providing a normally-open and a normally closed set of contacts, with a shared 'common' screw terminal.

The RY024AM relays are designed to easily surface mount right onto the finished wall by means of self-stick mounting tabs (provided by others) or by using the mounting holes provided for screw mounting. Convenient mounting holes also allow these relays to be mounted behind calling devices by means of a cable tie or wire wrap.

Connections are positive screw terminal type, using a barrier type terminal connector strip.
