F3CX04-0N | Yokogawa - Temperature Monitoring Module

Product Overview

The Yokogawa F3CX04-0N is a 4-channel universal temperature monitoring module for the FA-M3 series. It accepts Thermocouple, RTD (Resistance Temperature Detector), and DC voltage/mV inputs, providing flexible temperature measurement across critical industrial processes. With a 200 ms sampling period for all four channels and 0.1% conversion accuracy, it delivers precise, timely temperature feedback for process control applications.

Compatibility & Applications

Installs in any standard I/O slot of FA-M3 base modules. Perfect for heat treatment ovens, chemical reactors, HVAC systems, food processing, and pharmaceutical sterilization where multi-channel temperature monitoring with alarm functionality is essential.

FAQ

• Q: Can each channel be configured for different sensor types? A: Yes, each of the 4 channels is independently configurable for TC, RTD, or DC voltage inputs.
• Q: What is the isolation rating? A: 1500V AC for 1 minute between input terminals and internal circuit, using photocoupler and transformer isolation.
• Q: Does it support alarm delay? A: Yes, the ON-delay function prevents nuisance alarms from brief temperature spikes.
• Q: Is external power required? A: No, the module is powered directly from the FA-M3 backplane.

Installation Guide

1. Power off the FA-M3 system.
2. Insert F3CX04-0N into any available I/O slot on the base module.
3. Connect temperature sensors to the detachable 18-point terminal block (M3.5 screws).
4. Configure input types and alarm setpoints via WideField3 programming software.
5. Restore power and verify input LED indicators match sensor status.
6. Calibrate if necessary using known temperature references.

Selection Tips

• Use F3CX04-0N when you need universal temperature inputs (TC + RTD + DCV) in a single module.
• For higher channel counts, consider multiple F3CX04-0N modules or F3CX08 variants if available.
• Ensure sensor wiring uses shielded cables to maximize noise immunity in high-EMI environments.
• Pair with F3CU04-1S PID module for closed-loop temperature control applications.
