Product Overview

The Siemens part 6ES7231-7PB22-0XA0 is an EM 231 analog input expansion module for the SIMATIC S7-200 (particularly S7-22X CPU) series. It adds two precision RTD (resistance temperature detector) inputs to the base CPU, enabling temperature measurement using Pt and Ni RTDs or resistive sensors. Its function is to extend the S7-200 controller's analog input capability for industrial control, data acquisition, or temperature monitoring tasks. Now discontinued, it served applications such as industrial process control, factory automation, and machine temperature monitoring.

Best Suited For

  • Extending S7-22X CPU analog RTD input capacity
  • Temperature measurement with Pt100 / Pt1000 RTDs
  • On-machine control requiring precise RTD sensing
  • Spares for legacy S7-200 installations
