JBtek 4 Channel Relay Module with 6 pin cable Review

Disclosure of Material Connection: I received this product for free so that I could provide product feedback to the company and post a product review. I was not required to write a positive review and I do not rate products higher than they should have been. I am disclosing this in accordance with the Federal Trade Commission's requirements.

I recently received a JBtek 4 Channel Relay Module with 6 pin cable for a product review. The package just included the relay module and the 6 pin cable.  One of the plastic covers on the pin was missing, but that wasn’t an issue for me and the company advised they would resolve the issue if needed.

 The relay module did not have any documentation with it, so I had to do a little research online to figure out how to use it.  The board pins were labeled, but I wasn’t sure what signal to send to the relay pins -- it seems you need to connect the pin to ground/low signal to active the relay.

Each of the 4 relays has a normally open and normally closed connection, so you can decide which one you need for your project.  Each relay also has a corresponding LED on the module which is a great way to confirm which one is active/not active.

Using my Arduino board, I was able to do a few simple tests and have the relays turn off and on just to ensure everything is working.

Here are the main points I noticed about this product:

Easy to Wire: Wiring everything was fairly simple, the connections you need on the relay module for power and signal have pins you can connect to and the connections controlled by the relays have screw terminals.

Easy to Use: Once you connect the power, you just need to use a switch or microcontroller to provide the correct low/ground signal to active the relay.

Neat for projects: This relay module allows you to control power to other devices, opening up a wide range of potential projects.

Bottom line: If you are looking for a relay module, this is a great option to consider and JBtek has other options ( 2 channel and 8 channel ) to match your needs.
