LINEAR MID-RANGE RECEIVER, 4-CHANNEL
RF CONTROL FOR MORE THAN 10 MILES!!
The Model LNXR4 4-Channel Mid-range Receiver is designed for use in various wireless remote control applications. When the Model XR-4 receiver detects a signal from its companion transmitter, it will verify the digital code, activate the correct output channel, and trigger the remote device connected to the receiver.
The XR-4 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 outputs to follow the transmitter's inputs, each output staying activated as long as each transmitter input is activated. Alternately, an auto-restore option can be selected in the transmitter, causing a momentary receiver output each time any transmitter input is activated. If the transmitter sends a low battery signal, the receiver's low battery output will activate.
Power for the XR-4 receiver can come from an external 12 VDC power supply (Linear Model LNT1224DC) or from a 12-volt battery. A diode protects the unit from reverse power polarity. The XR-4 draws about 30 mA standby, and about 190 mA when all outputs are active. The receiver outputs provide isolated N/O and N/C relay contacts for each channel capable of switching a maximum of 1 Amp @ 32 VDC each. The low battery and status outputs are solid state and are capable of switching up to 50 mA @ 20 VDC to ground.
LINEAR'S XTENDED RANGE GETS YOU THERE
Linear's Xtended Range wireless receivers and transmitters are more than twice as powerful, 6 times more sensitive, and 3 times more immune to interference than the next best mid-range wireless equipment. Linear once offered the industry's top range at 5 miles, now with this new technology, they go to 10 miles. Maybe 15!
