Product Description: 6ES7231-5QF32-0XB0

The 6ES7231-5QF32-0XB0 is an 8-channel thermocouple input module for the SIMATIC S7-1200 PLC family. It supports direct connection of standard thermocouple types (B, E, J, K, N, R, S, T) in 2-wire mode, providing high- resolution temperature measurement (16-bit) with cold-junction compensation. Snap-on mounting beside the CPU draws power and communication through the backplane, enabling compact and precise temperature acquisition in food, pharmaceutical, HVAC, or OEM applications.

Key Features

  • 8 isolated thermocouple inputs, 2-wire
  • Supports B, E, J, K, N, R, S, T types per channel
  • 16-bit resolution (~0.1 °C) with built-in cold-junction compensation
  • Per- channel diagnostics: open-circuit detection and range error
  • Configurable filter time, scaling, and limits in TIA Portal
  • Status LEDs for each channel and module health

Technical Specifications

  • Input Range: Depends on TC type (e.g. –200…+1372 °C for K)
  • Resolution & Accuracy: 16-bit; ±0.1 % of full scale
  • Conversion Time: ~200 ms per channel
  • Isolation: 500 V DC channel-to-backplane
  • Power Consumption: 1.5 W from backplane
  • Module Width: 45 mm
  • Operating Temp.: –20 … +60 °C
  • Protection Class: IP20 (cabinet mount)
  • Weight: ≈ 180 g

Application Areas

  • Multi-point temperature monitoring in processing plants
  • Oven and furnace control for plastics, ceramics, or metal
  • Food and beverage production lines
  • Environmental chambers and HVAC control
  • OEM machinery requiring integrated TC inputs

Advantages

  • High channel count in a slim footprint maximizes panel density
  • Direct TC connection eliminates need for external transmitters
  • Built-in compensation and diagnostics ensure measurement integrity
  • Seamless configuration and maintenance via TIA Portal
  • Siemens industrial build quality for reliable 24/7 operation
