Product overview

The Siemens 6ES7231-5QD32-0XB0 is a SIMATIC S7-1200 SM 1231 4-Channel Thermocouple Input Module used for four-channel thermocouple temperature measurement in s7-1200 systems. Typical applications include furnace and heater temperature monitoring and packaging and process-machine temperature acquisition.

Selection must follow the complete Siemens article number rather than appearance alone. Before ordering, confirm thermocouple type and configured measuring range, cold-junction compensation method, shielding, grounding and extension cable, cpu firmware, tia portal project and module position.

COMMON APPLICATIONS

Installed-system context

  • Furnace and heater temperature monitoring
  • Packaging and process-machine temperature acquisition
  • Four-channel thermocouple expansion

Tell us the controller, communication network and installed panel details. That context helps prevent a visually similar but incompatible replacement.
