4 Channel Relay Module 5V 4 Channel Relay Module High And Low Level Trigger With Opto Isolation Features: MD optocoupler isolation, driving ability, stable performance; trigger current 5mA. Each channel module can be set high or low level triggered by the jumper. Power indicator (green), 4 Relay status indicator (red) When com with low short circuit, triggering the corresponding relay is low, and high when com shorted Channel: Channel 4 Operating Voltage: DC 5V Max Load: 250VAC 10A/ 30VDC 10A Each channel has an LED light indicating the operating status of the relay. This is a relay power supply with terminal blocks and a DC power outlet two kinds of interface forms, the use of more flexible and more convenient. With a diode freewheeling protection circuit. With the use of a dual power supply, the user can according to need, through the short-circuit cap, select the power supply to use more flexibly and conveniently.
