5V 2 Channel Relay Module Shield

 2 road with light coupling relay module
Module parameters:
1. Size: 50.6 mm (length) * 38.8 mm (width) * 19.3 mm (high)
2. Weight: 30 g
3. PCB color: black
4. The board with four fixed screw holes all round, hole diameter is 3.1 mm, convenient installation and fixed
5. Loose relay, relay selection of quality single pole double throw. A common end and a beginning, a normally closed end
6. Optical coupling isolation, anti-interference performance is good
7. Low level off, released in high level. Suction state indicator right, release the state when the light is out
8. VCC for system power, JD_VCC power supply for the relays. The default 5 v relay, with jumper cap
9. Maximum output relay: 30 v / 10 a dc, ac 250 v / 10 a
Connection details:
VCC: the anode system power
The cathode GND: system power
IN1 - IN2: relay control port
