Siemens 6ES7134-4GB11-0AB0 Analog Input Module

Siemens 6ES7134-4GB11-0AB0 is a SIMATIC ET 200S analog input module that provides two current-input channels (2AI) for the ET 200S distributed I/O system. This card is the 15 mm‑wide, I‑4DMU variant configured as an analog electronic module (I 4WIRE ST), suitable for connecting 4‑wire transmitters and standard wiring schemes. Each of the two channels accepts current signals in the 4–20 mA range, with a 13‑bit signed resolution for standard inputs and 12‑bit resolution used for 4‑wire transmitters, enabling precise digital representation of sensor currents. The module delivers a conversion cycle time of approximately 65 ms per channel, which supports reliable data updating in many industrial control tasks, and it features an SF LED to indicate a group fault for quick diagnostics. As part of the ET 200S family, this card integrates with compatible ET 200S bases and power modules to form a decentralized I/O solution for PLC systems, typically used to monitor two independent current-loop sensors or transmitters in automation projects. The article number 6ES7134-4GB11-0AB0 identifies this specific 2‑channel analog input module within Siemens’ ET 200S lineup.
