Yokogawa F3CU04-1S Temperature PID Control Module

The Yokogawa F3CU04-1S, also cataloged as the F3CU04-1S Temperature PID Control Module, operates as a dedicated hardware component for multi-loop temperature regulation within FA-M3 Range-Free Multi-Controller systems. It provides direct execution of continuous and time-proportional PID outputs for simultaneous heating and cooling control across four independent loops.

Process Control Features

The module supports isolated input channels for precise loop-to-loop regulation and cold junction compensation (CJc) for thermocouple inputs. Continuous 4-20 mA outputs integrate directly with analog actuators, while embedded dynamic auto-tuning recalculates PID constants based on setpoint changes. Channel-to-channel isolation reduces electrical interference between loops.

Frequently Asked Questions

Q: VnA: Can the F3CU04-1S be hot-swapped without system interruption?
A: No, this module requires power-down prior to insertion or removal to maintain loop integrity.

Q: VnA: Are the PID parameters retained after power loss?
A: Yes, all setpoints and PID constants are stored in internal non-volatile EEPROM.

Q: VnA: What is the maximum backplane current draw per module?
A: The module consumes 470 mA at 5 VDC, and backplane ratings should account for cumulative loop modules.

Field Installation Guidelines

• Mount the module in a vertical orientation on the FA-M3 base plate.
• Connect external devices to the 18-point terminal blocks using M3.5 screws; torque to recommended industrial standards.
• Maintain at least 20 mm spacing between modules to prevent thermal buildup.
• Ensure signal cables are shielded and grounded at one end to minimize electrical noise.
• Avoid routing high-voltage AC lines parallel to thermocouple or RTD wiring to prevent cross-talk.
• Allow a minimum warm-up of 30 minutes before critical loop tuning operations.
