1.Power Supply Voltage:12V (VIN+ connects with 12V positive,GND- connects with 12V negative)

2.Board Size:45*65*20mm

3.Quiescent Operating Current:<=1mA

4.Whole Absorption Current:<150mA

5.Max Remote Control Distance:8M

6.Relay Loading Capacitiy:250V AC-10A;125V AC-10A;30V DC-10A;28V DC-10A

7.Operating Principle:when press CH1,the relay 1 will operte and LED1 will be on;if press again,relay 1 will release and LED1 will be off;CH2 key can control relay 2 and LED2 in the same way;and CH3 and CH4 so on;the power key on remote control can control all the relays absorption and release in the same time.
