Dual Channel Active Low Relay Board
Control AC devices with 0-5 volt signals !
This listing is for a dual channel active-low relay board. The video above gives you a full demonstration of how it works! It requires a power supply of 5 volts. Each relay activates when the relative input line is drive low (0v), hence "Active-low". There are four input pins:
VCC - 5v Supply Line
GND - DC Ground
IN1 - Input#1: Acts to control relay#1
IN2 - Input#2: Acts to control relay#2
There is an output terminal block for each relay, but these ports are labelled in Chinese. I talk about the pin out of the relay terminal blocks in the video. The relays are SPDT, so each of the relays has a common pin, a normally connected pin, and a normally open pin. If you have any questions, please do not hesitate to ask. Please see below for specifications =)
Specification:
Supply Voltage: 5v
Height: 17mm
Length/Width: 45mm
Relay Contact Ratings: 10A @ 250VAC / 10A @ 30VDC
