1x 8 Channel Active Low Relay Board
Control up to 8 AC devices! COOL!
PLEASE NOTE THAT THE RELAY BOARD BEING SOLD IN THIS LISTING IS NOT THE EXACT ONE IN THE VIDEO. IT IS OF THE SAME QUALITY, AND LOOKS VERY SIMILAR. THE VIDEO ABOVE IS BEING USED AS REFERENCE BECAUSE THEY HAVE THE SAME FUNCTIONALITY.
This listing is for an eight channel active-low relay board. The video above gives you a full demonstration of how it work! 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 ten input pins:
VCC - 5v Supply Line
IN1 - Input#1: Acts to control relay#1
IN2 - Input#2: Acts to control relay#2
IN1 - Input#3: Acts to control relay#3
IN2 - Input#4: Acts to control relay#4
IN1 - Input#5: Acts to control relay#5
IN2 - Input#6: Acts to control relay#6
IN1 - Input#7: Acts to control relay#7
IN2 - Input#8: Acts to control relay#8
GND - DC Ground
There is an output terminal block for each relay, but these ports are labelled as a matter of function. The middle pin is always the common pin. There is a footprint on the common pin outputs for each terminal block that points to the normally closed pin. The normally closed pin is on the left hand side of each terminal block when looking at the board from the front side (LED side). By default, the common pin is connected to the normally closed pin. When a relay activates, the common pin on that relay will disconnect from the normally close pin, and connect to the normally open pin. The normally open pin is on the right side of each terminal block when looking at the board from the front side (LED side). In the video, the talk of the terminal blocks pertains to my explanation above, only I am talking about a slightly different board, so please consider this when you purchase. This board is very easy to use. If you have any questions, please do not hesitate to ask. Please see below for specifications =) There are four mounting holes; one on each corner.
Specifications:
Supply Voltage: 5v
Height: 17mm
Length: 138mm
Width: 38mm
Relay Contact Ratings: 10A @ 250VAC / 10A @ 30VDC
