40T-20产品概述
The Series 40T/40M Digital Temperature Switches accept a variety of inputs to allow temperature measurements and set points up to 1999?F (1300?C). Observing the current status of the control is made easier with the 3-1/2 digit, multi-color LED display that has alarm, defrost and output symbols. For added versatility, the temperature units can be field selected for ?F or ?C. For cooling applications, manual defrost mode can be initiated by pushing a single button. A flashing alarm informs users when the current temperature exceeds preset limits. When programming multiple units, a programming key is available to reduce set up time.
