Versatile six motor 12VDC Polarity Reversing R.F. Remote Control transmitter & receiver are designed for bi-directional control of up to six DC motors. The output relays are rated at 30A @ 12VDC. This system is ideal for controlling lifts, jacks, winches, slide outs, awnings and agricultural applications where 12VDC polarity reversing DC motors are used. The receiver electronics are encapsulated for waterproofing and it is suitable for use in harsh environments. The input has reverse polarity protection. Operating temperature range – 0° F to 160° F. Receiver dimensions are approximately 5″ L x 5″ W x 2″ H. Transmit range is greater than 100 feet under normal operating conditions. FCC Approved. The transmitter has two buttons assigned to each of the six outputs. The up ( ^ ) button runs the motor in one direction and down ( v ) button runs the motor in the opposite direction. The outputs are energized for as long as the buttons are depressed. The transmitter is designed to be waterproof to an IP65 level (protection from dust, rain and water spray). It is not deigned to be submerged.
