Technical FAQ & Selection Guide
- What is the advantage of using the built-in PID function in the AH04TC-5A?
It reduces the communication load between the module and the PLC CPU, ensuring more stable and accurate temperature control. - Can I use this module for high-voltage environment temperature sensing?
Yes, the isolated signal design protects the internal PLC circuitry from high common-mode voltages and electrical surges. - How do I troubleshoot a ‘sensor error’ indicated on the module LED?
Check the terminal connections and use the software diagnostic tool to confirm if the disconnection detection has been triggered. - Experience Tip: Why should I choose thermocouple over RTD for my AH500 system?
Select the AH04TC-5A when you need to measure a wider temperature range (especially high heat) or require faster response times than RTDs. - Selection Guide: Is this module compatible with K-type sensors only?
No, it is highly versatile; you can configure it via software for nearly all common thermocouple types including S and R for high-temp furnaces.
