Siemens 6ES7431-1KF10-0AB0 Programmable Logic Controller Module

Siemens 6ES7431-1KF10-0AB0 is an 8-channel analog input module for the SIMATIC S7-400 family (SM 431), delivering 14-bit resolution and galvanic isolation for each channel to read a variety of sensors. It accepts voltage (U), current (I), resistance, thermocouples, and Pt100 RTDs, enabling direct interfacing with common process signals. Powering and wiring: the module uses a 24 V DC load supply on L+ for two-wire transmitters, while the backplane provides 5 V DC (up to 600 mA) to the module. As part of the SM 431 analog input family, the PM400 series is listed with a phase-out notice (end of life) with PM300 active status; check regional availability.
