Siemens 6ES7134-6GD01-0BA1 Analog Input Module

The Siemens 6ES7134-6GD01-0BA1 Analog Input Module, AI 4XI 2-/4-Wire ST, is a four-channel analog input card for the SIMATIC ET 200SP distributed I/O system. It provides four differential inputs that accommodate 2-wire or 4-wire sensors, delivering 16-bit resolution with an accuracy of ±0.3% to support precise conversion of sensor signals. The module supports diagnostics (MODULE DIAGNOSIS) and exposes I&M data (I&M0 to I&M3) for maintenance and traceability, while offering scalable measuring ranges to match connected sensors. It is designed to fit BU-type A0 or A1 base units, is labeled with color code CC03, and ships as a single piece. In terms of performance, the module emphasizes robust common-mode rejection (minimum around 90 dB), making it suitable for industrial environments where electrical noise can affect measurements. As part of the ET 200SP family, this AI module enables reliable, modular expansion of analog input channels for process and automation applications requiring four precise input channels and straightforward integration with Siemens controllers.
