Siemens 6ES7134-4GB00-0AB0, ET 200S 2AI 4-20 mA, 13-bit

The Siemens 6ES7134-4GB00-0AB0 is an ET 200S analog input module built for the pit — two channels, 4-20 mA on 50 ohms, integrating measurement with parameterizable digital filtering. It lives on the ET 200S power module bus, drawing 24 V DC from it. The 15 mm width keeps slice count dense when you're packing I/O into a cabinet that's already tight for space. 13-bit resolution over 4–20 mA range with 0.4 % current accuracy relative to input range. Conversion time per channel is 55 / 65 ms; integration time adjustable to 16,7 / 20 ms with four-stage digital filtering. Diagnostics cover wire break (only in 4-20 mA mode), overflow/underflow, and group error via the red SF LED. Wire break and group error can be enabled or disabled per channel. Shielded cable runs up to 200 m — fine for tying back to field transmitters in a mill. Isolation tested at 500 V DC between channels and backplane bus.
