F3CU04-1S | Yokogawa 4-loop Temperature Control and PID Module

Product Overview

The Yokogawa F3CU04-1S is a 4-loop temperature control and PID module for the FA-M3 series. Each loop independently supports RTD, thermocouple, and DC voltage inputs with 200 ms sampling and ±0.1% accuracy. Advanced control modes include single loop, cascade, and two-input changeover, making it a complete temperature control solution integrated directly into the PLC rack.

Compatibility & Applications

Compatible with all FA-M3 base modules (occupies 2 consecutive slots). Perfect for plastic extrusion temperature control, heat treatment furnaces, chemical reactor temperature regulation, HVAC multi-zone control, and food processing ovens requiring precise multi-loop PID control.

FAQ

• Q: Does each loop need external power? A: No, the module is powered entirely from the FA-M3 backplane (470 mA at 5V DC).
• Q: Can I use different sensor types per loop? A: Yes, each of the 4 loops is independently configurable for RTD, TC, or DC voltage.
• Q: What is the output type? A: Time-proportional open collector output for driving external SSRs or contactors.
• Q: Does it support auto-tuning? A: Yes, the module supports PID auto-tuning for each independent loop.

Installation Guide

1. Power off the FA-M3 system.
2. Reserve 2 consecutive horizontal slots in the base module.
3. Install F3CU04-1S in horizontal orientation only (vertical installation not supported).
4. Connect temperature sensors and output devices to the two 18-point terminal blocks.
5. Configure input types, PID parameters, and alarm setpoints via WideField3.
6. Restore power and verify temperature readings and control outputs.

Selection Tips

• Use F3CU04-1S for multi-loop temperature control (up to 4 zones) within the FA-M3 rack.
• For 4 loops with enhanced features, F3CU04-0S is the successor/replacement model.
• Ensure the module is mounted horizontally; vertical orientation will cause inaccurate readings.
• Allow 30 minutes warm-up time before critical control operations.
