Siemens 6ES7 134-6GD01-0BA1 Digital Input Output Module

Siemens 6ES7 134-6GD01-0BA1 is an analog input module for the SIMATIC ET 200SP distributed I/O system that provides four AI channels (AI 4XI) capable of reading signals from 2-wire or 4-wire sensors and delivering digital values to the connected PLC via the ET 200SP backplane, with designation AI 4XI 2-/4-Wire ST. Each channel operates at 16-bit resolution, supporting an accuracy of approximately ±0.3%, and the module includes built-in diagnostics to report channel status and overall health, enabling rapid fault isolation in industrial environments. The unit ships as a single packing unit (PU 1) and is designed to fit BU-type backplanes A0 and A1, using color code CC03 for straightforward identification and integration. As part of the ET 200SP family, the AI 4XI module plugs into Siemens controllers through the standard ET 200SP interface, serving as a reliable input stage for analog process signals in automation tasks such as monitoring, data logging, and closed-loop control.
