Rated 4 out of 5 by from Decent little controller These little controllers come with a good array of features for the price. However, the mounting clips they come with are cheap, easily broken, and very difficult to get replacements without ordering a whole new controller.

Is the relay electromechanical or solid state? Is the relay enclosed?

Asked by: spock
The CN733 has one Relay: SPST, 5A @ 250 Vac resistive. Thanks for connecting with Omega. Please contact our Tech Support with any further questions.
