Frequently Asked Questions
Q: What input sensor types does the REX-CH PID temperature controller support?
A: The REX-CH series supports a wide range of input types, including thermocouples (K, J, R, S, B, E, N, T, W5Re/W26Re, PLII), RTD sensors (Pt100, JPt100), voltage inputs (0–5V, 1–5V), and current inputs (0–20mA, 4–20mA), making it suitable for a broad variety of industrial temperature measurement applications.
Q: What is the difference between the CH102, CH402, CH702, and CH902 models?
A: The model numbers refer to the physical panel size. The CH102 is 48×48mm, CH402 is 48×96mm, CH702 is 72×72mm, and CH902 is 96×96mm. All models share the same core PID control features, dual SSR and relay output, and 48–240V AC supply voltage — only the form factor differs to suit your panel cutout size.
Q: Can this controller be used with both PID and ON/OFF control modes?
A: Yes. The REX-CH series PID temperature controller supports both PID (Proportional-Integral-Derivative) and simple ON/OFF control methods. You can select the appropriate mode for your process via the touch switch interface, making it flexible for both precise industrial processes and simpler heating or cooling applications.
Q: What voltage supply does the REX-CH temperature controller require?
A: This controller operates on a wide supply voltage range of 48–240V AC, with power consumption under 10VA at AC 100–240V. It is compatible with most standard industrial power supplies worldwide.
