The SENTRY 403MHz Binary receiver is a receiver designed to receive and decode classic binary transmitters that operate in the 403MHz range.

It is a standard single channel receiver module that provides a 10 AMP potential free relay contact suitable for many applications, most commonly found in situations where a gate or door automation product is used. 
The receiver is easy to configure by means of dipswitches. The instruction manual details more features that are optionally selectable by the user, such as the split modes.
