Electronic Temperature Control, Series 59, from Fenwal is available as either a 24 VAC or a 120/208/240 VAC selectable on/off controller that can support solid state, thermocouple, RTD, or thermistor sensors. The electronic temperature control unit features two-button, menu-driven programmability and a large 3-digit LED display. These UL/CUL/CE recognized electronic temperature control units install easily and lets manufacturers configure the program parameters per their own specifications.

The 59 Series of electronic temperature control units are accurate to <1% of span. The units provide programmable set-point temperature, adjustable differential from 2° F to 20° F, offset, and timer options to signal an alarm or shut down a process. The units display process and set point temperatures and offer probe-failure diagnostics with an error message display. The electronic temperature control units are software configurable for specific temperature ranges and sensor types.

Values are entered via push-button switches to configure the controller. A mechanical relay or an output for driving an external solid-state-relay (SSR Driver) is available.

Built for easy installation and operation, these new advanced microprocessor based ON/OFF electronic temperature control units offer features such as
