Engineering Decision Points
Match the thermocouple type
Configure the channel for the installed sensor and temperature range.
Preserve polarity
Use the correct extension cable and observe thermocouple polarity end to end.
Plan compensation
Follow Siemens guidance for cold-junction compensation and terminal conditions.
Control electrical noise
Use shielding, segregation and proper grounding for low-level TC signals.
Exact Product View
Selection boundary
Choose this module for thermocouples, not RTDs or standard current transmitters. Confirm the exact thermocouple type, extension cable, polarity and compensation method before wiring.
6ES7231-5QD32-0XB0 Overview
The 6ES7231-5QD32-0XB0 SM 1231 TC provides four thermocouple inputs for temperature measurement in SIMATIC S7-1200 systems. It is intended for low-level thermocouple signals where sensor type, compensation and noise control are central to measurement quality.
Typical Applications
System Compatibility
- Use with supported S7-1200 CPUs and the matching TIA Portal catalog.
- Confirm thermocouple type, cable material and compensation arrangement.
- Install inside a suitable IP-rated cabinet and follow ambient limits.
