Description Well-built wireless controller and wireless relay module, you can setup this on your domestic appliance or similar items immediately. Medium level security based on learning code system. Suitable for anti-theft alarm, remote control electric windows, signal control, industrial control, lifting equipment, electrical control circuitry. Up to 270V AC /10V controlling capability. When the wireless encoder controller is lost, you only need to get another 315mhz control for the system, no need any changes to be done for the decoder, except re-pair them. Also multiple encoder controller can work on the same time for one decoder board. Input voltage: DC 12V, current must support up to 500ma. Working frequency: 315Mhz. Wireless distance: 200 Meters in open area in theory, but actually can reach 20 ~100 meters depending on environment and obstacles Sensitivity: >-105dB. Decoder board can decoding any oscillation resistor. Support three different working mode for buttons output, see this three modes here. Soldering T is self-locking (PinK2) Soldering M is non-locking type by jumper (PinK1) Neither M and T are not soldered to the interlocking type Key programming PinK3 Board connection – to DC ground to DC 12V power supply COM and NO insert between phase/live wire, ground/earth wire does not need to connect. NC do not need to connect. (Com and NC will keep connected when button not pressed) Package including the encoder controller, decoder relay board, and decoder relay board case. Documentation: See how to pair it in demo video Documentation page. More explanation about fixed code and learning code.
