Frequently Asked Questions
Q: What sensor types does the CKCTINNER CHB PID temperature controller support?
A: The CHB series supports a wide range of universal inputs, 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 makes it compatible with virtually any industrial temperature-sensing setup.
Q: What is the difference between PID and ON/OFF control on this unit?
A: PID (Proportional-Integral-Derivative) control uses auto-tuning algorithms to achieve smooth, stable temperature regulation with minimal overshoot — ideal for processes that demand tight precision. ON/OFF control is a simpler mode that switches the output fully on or off at your set threshold, suitable for less critical applications.
Q: What panel cutout size do I need for the CHB series controller?
A: The required cutout depends on the model variant. For example, the REX-CH102 needs a 45×45 mm cutout, the REX-CH902 needs a 92×92 mm cutout, and other models range in between. Check the size table above to match your existing panel opening before ordering.
Q: Is the CHB temperature controller CE certified?
A: Yes, the CKCTINNER CHB series carries CE certification, confirming it meets applicable European safety and electromagnetic compatibility standards for industrial control equipment.
