Use this board to replace many burned out pump relays with a generous 16-Amp
This board can be assembled as a "left hand" and "right hand" version - depending on whether you need the positive (+) on the left or the right and is therefore supplied unassembled.
You need to be able to identify the polarity of the original mechanical relay on the board. The polarity does not matter for the original relay, but is important for the new Solid State Relay.
We are happy to help where possible - you can send us photos / test results and we will try to help you.
