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

Product Description

The Siemens 6ES7131-4BF00-0AA0 is a 4-channel digital input module for the SIMATIC ET 200S distributed I/O system, designed to acquire signals from sensors, switches, and other binary devices. Compatible with PROFIBUS and PROFINET networks through the ET 200S interface, it ensures fast, reliable, and isolated signal acquisition in a compact modular format.

Equipped with LED diagnostics for channel status and fault monitoring, this module simplifies maintenance and troubleshooting. Its design allows flexible expansion of ET 200S racks, making it suitable for a wide range of automation and monitoring applications. While still active in the ET 200S line, it is gradually being replaced by ET 200SP modules.
