Frequently Asked Questions
Q: What does the REX-C100 Digital Temperature Controller SSR Output do?
A: The REX-C100 is a PID digital temperature controller that reads temperature via a K-type thermocouple sensor and switches a connected Solid State Relay (SSR) to turn heating or cooling elements on and off, maintaining your desired setpoint with high accuracy. It is widely used in DIY projects, incubators, kilns, 3D printers, brewing, and industrial automation.
Q: What type of sensor does the REX-C100 use?
A: This model is configured for a K-type thermocouple sensor, one of the most common and versatile thermocouple types, suitable for a broad temperature measurement range. Ensure you connect a compatible K-type thermocouple for accurate readings.
Q: What is the difference between SSR output and relay output?
A: An SSR (Solid State Relay) output switches electronically with no moving parts, resulting in silent, faster, and longer-lasting switching compared to a mechanical relay. The REX-C100 SSR output version is designed to drive an external SSR module (such as an SSR-40DA), making it ideal for high-cycle applications like 3D printers or precise temperature control systems.
Q: What panel cutout size does the REX-C100 require?
A: The REX-C100 requires a standard 45 × 45 mm panel cutout (front bezel is 48 × 48 mm) and mounts securely with the included panel clips. The unit depth behind the panel is 88 mm.
