ISOLATOR - Irrigation Controller Protection / Protect Multi-controller Systems From Interconnection Issues

Did the job! We went from 12 zones to 24 with 2 controllers. We purchased one isolator per controller, as instructed. It’s easy to install and comes with directions. You’ll hear a slight click when they isolate signals if you’re in front of the units however this is absolutely normal.

Fulfillment quicker than the non-irrigation items on the same order shipped from Amazon's fulfillment service.Installation instructions and diagrams are clear and not overly technical. Nonetheless, I had question and received a helpful answer in less than 24 hours. The ISOLATORs look durable and have a clean design, prepared wiring, and supplies for screw or glue pad attachment. It was very straightforward to install.

I have a sprinkler controler and a main valve to turn on supply to hose bibs too. This product was exacly what was needed to protect the main valve curcuit in the controler when i just want to turn on the main valve for the hose bibs. Works great.

If you have a system that shares wire with two controllers this protect them.

I have a large lot and require two sprinkler controllers. This isolates them as advertised, and was very easy to install. Clear instructions.

worked perfectly on both controllers (Rain Bird and Hunter) with the same master valve.

Works just as described, I used them to hook 2 controllers to 1 pump relay. and very clear directions.

Very easy to install. Just what I needed to run 2 controllers. Thanks
