SIMATIC S7-400 SM 431 | Isolated 8-channel analog input module with 13-bit resolution
The Siemens 6ES7431-1KF00-0AB0 is a SIMATIC S7-400 SM 431 analog input module for acquiring industrial measurement signals in an S7-400 station. Siemens identifies eight isolated analog inputs with 13-bit resolution and measuring ranges for voltage, current and resistance. The module is intended for process and machine applications that require centralized analog signal acquisition in the S7-400 platform. Procurement and maintenance teams should verify the complete suffix, module slot, signal type, measuring range, channel wiring, front connector, parameter assignment, rack power budget and STEP 7 hardware configuration. The 13-bit 1KF00 variant must not be confused with the 14-bit 1KF10 version.

Confirm the complete 6ES7431-1KF00-0AB0 order code and compare the installed label with the project hardware catalog. Review the 13-bit measuring configuration, voltage/current/resistance ranges, channel wiring, rack slot, front connector, isolation requirements and parameter assignment. Do not substitute the 1KF10 or another SM 431 version solely because the family name is similar.
Siemens lists the exact 6ES7431-1KF00-0AB0 as PM300: Active Product and states that product phase-out starts 01.10.2025. This is not a Discontinued classification. Procurement planning should still verify the order code, current availability and project-specific compatibility for the installed S7-400 configuration.
