System 350™ is a modular, electronic control series encompassing a wide variety of on/off and proportional temperature, humidity, and pressure applications, as well as temperature reset. The basic system consists of a control module, which accepts stage, display and transformer modules. A variety of temperature, pressure, and humidity sensors are also available. Hundreds of different control systems can be configured using a combination of the controls and their accessories. Five-pin connectors eliminate wiring betwen modules, minimizing installation costs, and reducing wiring errors. The modules can be DIN rail or surface mounted. All System 350 modules (except the CLK350-1 Time Control) are UL listed and CSA certified or cUL listed.
