Features: Multi-functional 8-way remote control switch - Adopts high-end MCU, with Flash can be repeatedly erased and written. 12V 8-way remote control switch - The layout of components is neat and the circuit wiring is orderly. Small size, strong performance and stable operation. The relay drive uses a high-current integrated chip, and the multi-channel control is more stable. The terminal is selected with a good screw cap, shrapnel, and high insulation plastic. Stable performance and high externality - The receiving module selects a highly integrated chip with high sensitivity. High-quality - After several cycles of testing, the program runs stably and the circuit works really well. Greatly improves work efficiency, and more convenient for multi-channel control and easy to operate. Specification: Type: 8-way Learning Remote Control Switch Product model: CJR-1208 Working voltage: 12V Working frequency: 433MZH Total load power: 500W Remote control distance: 100M Working mode: jog, self-locking, interlocking Weight: Approx. 208g PCBA size: Approx. 10 * 8 * 2.8cm / 3.9 * 3.1 * 1.1in Package list: 1 * 8-way Learning Remote Control Switch 1 * Remote Controller Each Data Bit Corresponds to A Relay 1. Power-on: Select DC-12V for the power supply to connect the ''+'' and ''-'' terminals, and the LED indicator lights up. 2. Pair code: Press the KEY learning button on the control panel, the LED indicator is off. At this time, the MCU has entered the code status. Press the same frequency remote control in your hand, and the LED indicator on the control board flashes 4 times continuously. Lights up, indicating that the code is successful 3. Test: Press the code remote control, the corresponding relay on the control panel works according to the function selected by the user, and the control board is the switch signal output. If you need a live output, you need to connect wiring. Function selection: Function 1: 8-way jog (jumper cap is empty) Function 2: 8 -ay self-locking (jumper cap 1, 2 short-circuited) Function 3: 8-way interlock (jumper caps 3, 4 short-circuited) Function 4: 4-way jog + 4-way self-locking (jumping cap 1, 2 short-circuited 3, 4 short-circuited) Note: 1. Please allow slight error due to manual measurement. Thanks for your kind understanding. 2. Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering. .
