Frequently Asked Questions
Q: What sensor type does the REX-C100 Digital Temperature Controller use?
A: The REX-C100 uses a K-type thermocouple sensor, one of the most widely used thermocouple types, offering a broad measurement range suitable for applications from food processing and brewing to industrial ovens and kilns.
Q: What is the output type of the REX-C100, and what can it control?
A: The REX-C100 features a relay signal output, making it compatible with a wide range of devices including electric heaters, cooling fans, solenoid valves, pumps, and other on/off actuators. Simply wire your load through the relay contacts and set your target temperature.
Q: How do I install the REX-C100 Digital Temperature Controller?
A: Installation is straightforward — the REX-C100 is designed for standard 1/16 DIN panel mounting. Cut a 45 × 45 mm hole in your panel, insert the unit from the front, and secure it with the included mounting clips. Connect your K-type thermocouple to the input terminals and your load to the relay output terminals, then power on and configure your set point using the front-panel buttons.
Q: Can the REX-C100 function as both a heating and cooling controller?
A: Yes. The REX-C100 supports selectable heating or cooling control modes, so you can configure it to energize the relay when the temperature falls below (heating) or rises above (cooling) your desired set point, making it versatile across many applications.
Q: What panel cutout size is required for the REX-C100?
A: The REX-C100 requires a standard 45 × 45 mm (1/16 DIN) panel cutout. Its overall body dimensions are 48 × 48 × 88 mm (±0.2 mm).
