Siemens 6ES7134-6HD00-0BA1 Analog Input Module

SIMATIC ET 200SP ANALOG INPUT MODULE AI 4XU/I 2-WIRE ST, model 6ES7134-6HD00-0BA1, adds four independent analog input channels to ET 200SP base units BU Type A0 or A1, designed for 2‑wire U/I sensors and delivering 16‑bit resolution with module diagnostics for on‑field I&M data. The module is powered from 24 V DC (19.2–28.8 V range) with reverse polarity protection and a maximum current consumption of about 37 mA without sensor supply, and it provides a dedicated 24 V encoder supply for connected devices. It fits to BU types A0/A1 and uses color code CC03 for identification, while offering I&M data (I&M0–I&M3) and straightforward integration with STEP 7, TIA Portal (as of V11 SP2 / V13), PCS 7, and supporting PROFIBUS (GSD Revision 5) and PROFINET (GSDML V2.3) networks. The AI 4XU/I 2-WIRE ST designation confirms four 2‑wire analog inputs configured to accept either voltage or current signals, enabling compact, scalable acquisition on a single ET 200SP module without external sensor power beyond the 24 V rail. This combination of four 16‑bit channels, diagnostics, and standard industrial communication support makes it a suitable choice for distributed analog sensing in automation architectures that require reliable, field‑level measurement with Siemens ET 200SP hardware.
