xr-4.jpg 10799 bytes)

The Model XR-1 1-Channel Mid-range Receiver is designed for use in various wireless remote control applications. When the Model XR-1 receiver detects a signal from its companion transmitter, it will verify the digital code, activate its output, and trigger the remote device connected to the receiver.

The XR-1 receiver has full supervision capabilities. If the status option is selected, the receiver expects hourly status signals from its transmitter. If these signals cease, the receiver will indicate trouble by activating its status output after four hours. Contact supervision allows the receiver's output to follow the transmitter's input, staying activated as long as the transmitter input is activated. Alternately, an auto-restore option can be selected in the transmitter, causing a momentary receiver output each time the transmitter input is activated. If the transmitter sends a low battery signal, the receiver's low battery output will activate.

Power for the XR-1 receiver can come from an external regulated 12 VDC power supply (Linear Model T-1224DC) or from a 12-volt battery. A diode protects the unit from reverse power polarity. The XR-1 draws about 30 mA standby, and about 70 mA when the output is active. The receiver output provides isolated N/O and N/C relay contacts capable of switching a maximum of 1 Amp @ 32 VDC. The low battery and status outputs are solid state and are capable of switching up to 50 mA @ 20 VDC to ground.
