It is widely used in DIY projects, incubators, kilns, 3D printers, brewing, and industrial automation.\u003c\/p\u003e\n\u003ch4\u003eQ: What type of sensor does the REX-C100 use?\u003c\/h4\u003e\n\u003cp\u003eA: This model is configured for a \u003cstrong\u003eK-type thermocouple\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the difference between SSR output and relay output?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: What panel cutout size does the REX-C100 require?\u003c\/h4\u003e\n\u003cp\u003eA: The REX-C100 requires a standard \u003cstrong\u003e45 × 45 mm panel cutout\u003c\/strong\u003e (front bezel is 48 × 48 mm) and mounts securely with the included panel clips.
