Product Overview
The Yokogawa F3CU04-1S Temperature PID Control Module is a high-precision, multi-loop control solution developed for the FA-M3 PLC platform. Designed to deliver stable and responsive thermal regulation, this module integrates advanced PID algorithms directly into hardware, allowing critical temperature processes to run independently from the main CPU cycle.
With support for both heating and cooling control, as well as continuous output capability, it is particularly suited for applications that demand tight process control and minimal temperature deviation. Its dual-slot architecture enhances functionality without compromising system flexibility, making it a powerful upgrade for complex automation environments.

Core Advantages
One of the defining strengths of this module is its independent control processing, which ensures consistent PID performance regardless of PLC scan load. This results in smoother temperature curves and reduced overshoot during dynamic operations.
The inclusion of continuous 4–20 mA output alongside time-proportional control significantly expands integration possibilities, allowing compatibility with a wide range of actuators and control devices.
Additionally, its dynamic auto-tuning capability simplifies commissioning by automatically optimizing PID parameters in real time. This reduces engineering effort while improving control accuracy.
The module also supports simultaneous heating and cooling control without sacrificing loop capacity, providing greater flexibility in advanced thermal systems.
