The PLC Jazz Satellite Controller is a control box with highly flexible programming settings used to regulate the operation of up to 10 Satellite Entryway Foam Sanitizers (or Trench Foamers) in applying rich foam to multiple entryway floors at programmed intervals, to prevent cross contamination from foot or wheeled traffic. Compressed air is used to activate and run the Satellite Entryway Foamers in accordance with a programmed schedule, without the need for electrical connections at the Satellites. Activation will start the flow of water/solution to the foamers; deactivation stops the flow of water/solution through the foamers. All foamers activate and deactivate at the same time.
