Global PLC Spare HUB's Insight

The FR-T0400K is remarkably versatile for its size. Most budget modules force you to choose between RTD or Thermocouple, but the FR-T0400K handles both. Our technical team finds this module particularly useful for retrofitting older furnaces where mixed sensor types are encountered. The 0.1% accuracy for NTC sensors makes it an elite choice for precise environmental monitoring.

Technical Expert FAQ

Can I mix different thermocouple types on the same FR-T0400K module?
Yes, each of the 4 channels can be configured independently for different sensor types via the software setup.

Why is NTC accuracy higher than Thermocouple accuracy?
NTC/RTD resistance changes are less prone to noise than the millivolt signals of thermocouples, allowing for higher resolution.

How do I handle signal interference from nearby VFDs?
Use twisted-pair shielded wire for thermocouples and ensure the shield is grounded only at the module end.

Does the module require an external 24V power source?
The module is powered via the 5V DC bus. Ensure your sensors are properly isolated from ground potential.

Selection Guide: Should I use PT100 or PT1000 with this module?
For long cable runs, choose PT1000 to minimize lead-wire resistance errors, which the FR-T0400K processes with high precision.
