Frequently Asked Questions

Q: What panel sizes are available for the REX-CH Series PID Temperature Controller?

A: The REX-CH Series is available in five panel sizes: CH102 (48×48 mm), CH402 (48×96 mm), CH502 (96×48 mm), CH702 (72×72 mm), and CH902 (96×96 mm). All models share the same 75 mm depth and the same dual relay output architecture, so you can choose the size that best fits your control panel cut-out.

Q: What sensor input types does this PID temperature controller support?

A: The REX-CH Series accepts a wide variety of input signals including thermocouples (K, J, R, S, B, E, N, T, W5Re/W26Re, PLII), RTDs (Pt100, JPt100), voltage inputs (0–5V, 1–5V), and current inputs (0–20mA, 4–20mA). This universal input capability makes it suitable for a broad range of industrial and laboratory applications.

Q: Can this temperature controller be used with a 110V or 240V power supply?

A: Yes. The CKCTINNER REX-CH Series PID Temperature Controller supports a universal power supply range of 100–240VAC, so it works seamlessly in both North American (110V) and European/international (220–240V) electrical systems without any modification.

Q: What is the difference between PID and ON/OFF control modes?

A: In PID mode, the controller continuously calculates and adjusts the output to maintain the setpoint with minimal overshoot and oscillation — ideal for processes requiring tight, stable temperature regulation. ON/OFF mode simply switches the output fully on or off when the temperature crosses the setpoint, which suits simpler applications where exact precision is less critical.
