Product Description

The F3CT04-0N is a specialized high-speed temperature control module developed for the Yokogawa Electric Corporation FA-M3 “Range-free” controller series.

This module integrates four independent PID control loops, enabling precise and autonomous thermal regulation without increasing the main PLC CPU load. It directly processes temperature inputs from thermocouples and RTDs, converting analog thermal signals into high-speed digital control outputs.

Engineered for applications requiring high stability and rapid thermal response, the F3CT04-0N maintains consistent temperature control even during PLC scan time fluctuations. Its independent loop execution ensures reliable operation in demanding industrial processes such as plastics manufacturing, semiconductor production, and fine chemical processing.

Detailed Technical Specifications

Application Scenarios

The F3CT04-0N is widely used in processes where thermal precision directly affects product quality and consistency:

• Plastic Injection & Extrusion: Maintaining stable barrel and die temperatures to prevent polymer degradation

• Packaging Machinery: Accurate heat-sealing bar control for high-speed film systems

• Semiconductor Processing: Tight temperature uniformity in wafer handling equipment

• Laboratory Furnaces: Implementing ramp-and-soak temperature profiles

• Environmental & Climate Chambers: Multi-zone temperature synchronization

The module’s built-in PID execution and fast sampling cycle enable smooth thermal transitions and minimized overshoot during setpoint changes.

FAQ

Does this module require an external power supply for sensors?
The F3CT04-0N provides internal excitation for RTD sensors. However, the transistor outputs used to drive external Solid State Relays (SSRs) require an external 24 V DC power supply.

Can different thermocouple types be mixed on one module?
Yes. Each of the four channels can be independently configured for a different thermocouple or RTD type using FA-M3 configuration software.

What is the “Super” function in the PID settings?
The “Super” function is Yokogawa’s proprietary overshoot suppression algorithm. It minimizes temperature overshoot during startup or sudden setpoint changes, which is especially critical in thermally sensitive processes.
