RKC Instrument Co., Ltd. REX-C400FK02-MAN Temperature Controller

RKC Instrument Co., Ltd. REX-C400FK02-MAN Temperature Controller is a digital PID temperature controller in the REX-C400 family, designed for reliable closed‑loop temperature control in industrial equipment. This FK02 variant provides a thermocouple input and a relay output, and includes two alarm contacts to flag high‑ or low‑limit conditions. It operates from a 100–240 V AC supply, a common configuration for panel‑mounted controllers in industrial environments, enabling straightforward integration with standard power wiring. The unit is intended for heating or cooling control applications, with programmable PID parameters that tailor response and stability to the process, and it supports typical thermocouple ranges up to 0–400°C in common configurations. As with other REX‑C400 instruments, FK02‑MAN emphasizes dependable, compact control with simple setpoint and alarm configuration, making it suitable for process steps such as heating elements, ovens, or furnaces where precise temperature tracking and reliable alerting are essential.
