4 way relay module

Relay modules suitable for switching of higher voltages and perfect for use with microcontrollers including Arduino, ARM, AVR and PIC. The relays used are rated up to 10A and have NO/NC contacts. Each channel has an LED indicator to show the relay is on.
Channels: 1,2 or 4
1. Active low
2. Connects directly to a microcontroller
3. LED Indicator for each channel
4. Switching Capacity: 10A
5. Maximum Voltage: 250VAC / 30VDC
6. PCB Color: Black
7. board four weeks with four screw holes, hole diameter 3.1mm, easy to install and fixed
8. Relay selection of quality loose music relays, SPDT. A common terminal, a normally open, one normally closed terminal
9. optocoupler isolation, good anti-jamming
10. low pull, high release. Energisation status indicator light, release status LED is off
11. VCC for the system power, JD_VCC for the relay power. Default hair 5V relay, plug the jumper cap to
Wiring:
VCC: positive power supply system
GND: System power supply negative
IN1 - IN2: relay control ports
