These controls utilize a single probe input for maintaining a level of liquid. A built-in time delay prevents rapid cycling. They are packaged in a standard octal plug-in housing. The probe and sensing circuit is isolated from line voltage via a transformer. The probe is driven with an AC signal to prevent plating. The output is an electro-mechanical relay rated at 10 A.
