The REX-C100 is the most compact at 48×48 mm (45×45 mm cutout), while the REX-C900 is the largest at 96×96 mm (92×92 mm cutout). All models share the same core PID control functionality, sensor compatibility, and output options — choose based on your panel space and mounting requirements.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I choose between Relay (MAN) and SSR (VAN) output?\u003c\/h4\u003e\n\u003cp\u003eA: Relay output (MAN) is ideal for directly switching resistive loads such as heating elements using a mechanical relay. SSR output (VAN) provides a low-voltage DC signal (typically 12V DC) to drive an external Solid State Relay (SSR), offering faster switching, longer service life, and reduced electrical noise. If you are unsure, SSR output (VAN) is the default and is recommended for most modern industrial applications. Please specify your choice in your order notes.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Which thermocouple types are compatible with the REX-C series controller?\u003c\/h4\u003e\n\u003cp\u003eA: The REX-C series supports a wide range of input sensor types, including thermocouples K, J, R, S, B, E, N, T, W5Re\/W26Re, and PLII, as well as RTD sensors Pt100 and JPt100. The most commonly used is the Type-K thermocouple, which covers a broad temperature range suitable for most industrial heating applications.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is PID control and why is it better than simple ON\/OFF control?\u003c\/h4\u003e\n\u003cp\u003eA: PID (Proportional-Integral-Derivative) control is an advanced algorithm that continuously calculates and adjusts the output to minimize the difference between the measured temperature and the target setpoint. Unlike basic ON\/OFF control — which simply switches the heater fully on or off — PID control reduces temperature overshoot, oscillation, and instability, resulting in much more precise and stable temperature regulation. This makes it the preferred choice for sensitive industrial processes.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the difference between the REX-C100, C400, C700, and C900 models?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The primary difference between the REX-C series models is their physical panel size and cutout dimensions.
