Digital temperature controller offers broad working range
New controller from Selco Products handles over 2,000 °F with easy configuration and installation.
Selco Products Company has introduced its second generation 2699B Electronic Temperature Controller offering a highly flexible temperature control solution in a compact, easy-to-install enclosure (75 x 33 x 70 mm). After extensive redesigning, the company says the new version offers an extremely affordable unit that includes a temperature range to over 2,000 °F, high functionality software, timer control for energy savings, multiple power and sensor inputs, multiple output types, and a variety of selectable hardware configurations. Typical applications include temperature control for commercial food equipment, heaters, refrigeration/freezers, and HVAC equipment.
The 2699B is a flexible all-in-one controller configurable to many applications by simply setting the software options and selecting the correct hardware configuration. Four different operation modes (on/off, with or without defrost, PID control, or timer) can be selected and fine-tuned to meet exact application requirements. Additional flexibility is provided by setting of a number of other variables. These include set-point, differential, actuator restrictions, alarms, and timers. Further versatility is provided with power inputs options of 115/230 Vac, 50/60 Hz, or 12-24 Vac and dc. Output choices include SPST relay rated at 10 or 3 A, or 12-24 Vdc for external SSR and buzzer alarm.
The 2699B is designed for cooling and heating control for temperatures between -40 °F (-40 °C) to 2,100 °F (1,100 °C) depending on sensor input. Other performance characteristics include a four-digit LED segment display for easy reading and configuring thermostat settings. Four push buttons for mode/menu, select/set, up, and down allow easy navigation. Programmability for setpoint or automatic shut-off provides reduced energy consumption.
"The 2699B offers one of the most flexible temperature control solutions available,” says Eugenio Pedroza, Selco products sales and engineering. "Combined with its wide temperature control range and integral electronics housed in a compact, easy-to-install package, OEMs will find it an excellent solution for many engineering designs."
