 3699A Electronic Temperature Controller
Flexible Configurability in Compact Package! Temperature Control to Over 2,000°F!Selco's 3699A Electronic Temperature Controller offers a highly flexible temperature control solution in a compact, easy-to-install enclosure (75x33x70 mm). Designed with minimal components, the result is an extremely affordable unit that includes a high temperature range to over 2,000°F, high functionality software, multiple power and sensor inputs, multiple output types and a variety of selectable hardware configurations. Unlike controllers that are limited to single use applications, the 3699A 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 input options of 115/230 VAC, 50/60 Hz or 12-24 VAC/VDC. Output choices include SPST relay rated at 10 or 3Amps or 12-24 VDC for external SSR and buzzer alarm. The 3699A is designed for cooling and heating control for temperatures ranging from -40°F/-40°C to 2012°F/1100°C, depending on sensor input. Other performance characteristics include a four digit LED segment display for easy reading and configuring of thermostat settings. Four push buttons for Mode/Menu, Select/Set, UP and Down allow easy navigation. Applications
