Beginning Late 2020, we’ve made some updates to this product to make it better with increased component count while maintaining the same functionality and footprint.  The New Rev G2 Series adds a better power supply circuit to improve noise immunity while providing increased power to the communications socket.  We also improved the relay drive circuit to better handle inductive loads.  We also changed the color of the circuit board to Black and updated the branding to ncd.io with updated logos.

This is the same product you have been buying for years, but now with improved electronics and while maintaining the same footprint as the original design.  Most importantly, this is now a Legacy product, which means it will never go obsolete as long as critical parts are still available to us.  Built with our new high-speed pick and place assembly line, we can complete the surface mount assembly process at a rate of several thousand units per day with the potential to scale to any volume you could imagine, so you never need to worry about supply quantities or supply chain problems.

Please note that it was necessary for us to remove the integrated temperature sensor in select versions of this product.  This sensor was providing incorrect readings if the relays were active for extended periods of time.  We can help you with an off-board sensor if needed.
