Product overview

The Siemens 6ES7231-5PF32-0XB0 is a SIMATIC S7-1200 SM 1231 8-Channel RTD Input Module used for eight-channel resistance-temperature and resistance measurement in s7-1200 systems. Typical applications include pt100 and pt1000 temperature measurement and multi-point machine temperature monitoring.

Selection must follow the complete Siemens article number rather than appearance alone. Before ordering, confirm rtd type and temperature range, 2-, 3- or 4-wire connection method, channel grouping, lead compensation and shielding, cpu firmware, tia portal project and module position.

COMMON APPLICATIONS

Installed-system context

Pt100 and Pt1000 temperature measurement
Multi-point machine temperature monitoring
Resistance-sensor acquisition

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