Product Description

The DXR-70 is a Digital Receiver with one or two isolated relay outputs designed for use with Linear's DX Format transmitters. This receiver can be used in a variety of remote control applications. When the receiver detects a signal from a transmitter programmed into its memory, the appropriate relay output activates. The relays have four optional output configurations.

In a typical installation, the receiver is connected to an alarm control panel, door strike, camera, high current relay or some other device(s). Transmitter(s) are used to activate or control the devices. The receiver should be mounted with the supplied mounting bracket indoors or outdoors inside a weather resistant non-metallic housing.

The digital DX code format features over a million possible codes. The DX transmitters are precoded at the factory to unique codes, so no field coding is required. Receivers must be programmed to the transmitter's code before system testing and operation. Up to 32 transmitters maximum can be programmed into the receiver.
