SIMATIC S7-400 SM 431 | Isolated universal analog input module with 14-bit resolution
The Siemens 6ES7431-1KF10-0AB0 is a SIMATIC S7-400 SM 431 universal analog input module designed for mixed industrial measurement tasks. Siemens documents eight isolated voltage or current inputs and four resistance-measurement channels, with 14-bit resolution and support for voltage, current, resistance, thermocouple and Pt100 signals. A 24 V DC load supply is required when two-wire transmitters are used. The module is intended for centralized process measurement in an S7-400 rack. Before procurement, verify the complete suffix, sensor type, measuring range, cold-junction method, two-wire transmitter load, channel wiring, front connector, rack power budget and STEP 7 parameter assignment.

Confirm the exact 6ES7431-1KF10-0AB0 order code and its 14-bit universal input configuration. Review sensor types, measuring ranges, thermocouple compensation, Pt100 wiring, two-wire transmitter load, rack current, front connector and STEP 7 hardware parameters. The 1KF00 variant has different resolution and measurement capabilities and must not be treated as a direct replacement without engineering review.
Siemens lists the exact 6ES7431-1KF10-0AB0 as PM300: Active Product and states that product phase-out starts 01.10.2025. This is not a Discontinued classification. Maintenance planning should separately verify signal types, wiring, supply requirements and project parameters for the installed S7-400 station.
