Siemens 6ES7131-4BF00-0AA0 Digital Input Module

Siemens 6ES7131-4BF00-0AA0 is an eight-channel digital input module for the ET 200S distributed I/O system, delivering eight 24 V DC digital inputs in a compact 15 mm-wide electronics module that plugs into the ET 200S backplane. It is a DC 24 V input module configured as a source-type input, meaning each channel accepts standard 24 V signals from field devices such as sensors, switches, pushbuttons, and proximity sensors, and it ships as 1 unit per packing unit with a green status indicator to show input activity. With eight inputs, the module expands digital input capability for small to mid-size automation tasks, enabling reliable monitoring of machine states, safety interlocks, and process signals within the SIMATIC ET 200S ecosystem. This module is part of Siemens' SIMATIC ET 200S distributed I/O family and is designed for straightforward integration into existing ET 200S configurations, offering compact installation and dependable operation in industrial environments.
