Siemens 6ES7134-4GB01-0AB0 Programmable Logic Controller Module

Siemens 6ES7134-4GB01-0AB0 is an ET 200S distributed analog input module that provides two current-input channels (2AI I 2WIRE ST) in a compact 15 mm-wide 2DMU. It is designed for remote measurement of 4–20 mA process signals, featuring a 50 ohm burden per channel and a rated input range of 4–20 mA, with reverse-polarity protection and a destruction limit of 35 mA per channel. The module is powered from the ET 200S backplane at 3.3 V (max 10 mA from the backplane) and typically consumes about 0.6 W; load voltage L+ is 24 V DC from the power module. Each channel converts the current with 13-bit resolution for 2-wire transducers, and the pair shares a cycle time of up to 65 ms. Address space per module is 4 bytes, enabling straightforward DP addressing. Shielded cables can run up to 200 m, supporting distributed installations, and the module includes SF LED indicators for group fault signaling, making it suitable for Siemens DP networks and ET 200S configurations.
