Siemens 6ES7134-6GB00-0BA1 SIMATIC ET 200SP AI 2xI 2-/4-Wire ST Remote I/O Module

The Siemens 6ES7134-6GB00-0BA1 is a SIMATIC ET 200SP analog input module with 2 current inputs wireable as 2-wire or 4-wire transducers, resolving up to 16 bit including sign over 0-20 mA, 4-20 mA, or -20/+20 mA ranges, fitted to BU type A0 or A1 with color code CC05.

Selection Notes

The 2-/4-wire designation means this module accepts either passive 2-wire loop-powered transmitters, drawing their supply from the module's 50 mA encoder output, or active 4-wire transmitters with their own supply, drawing from the separate 200 mA encoder output. Both wiring types land on the same 2 channels, so the choice is made per channel at commissioning rather than at ordering. The Sigma-Delta converter trades conversion time for noise rejection: 500 µs per channel with the filter off for fast loops, up to 180 ms at the 16.6 Hz setting for line-frequency-noisy 4-20 mA runs in electrically noisy cabinets. At ±0.3% basic error and ±0.01% linearity error, the module holds enough accuracy for standard process-transmitter feedback (pressure, level, flow) without needing a higher-accuracy analog card.

Applications

Reads 4-20 mA and 0-20 mA process transmitters on ET 200SP stations - pressure, level, flow, and temperature transmitters - in both 2-wire loop-powered and 4-wire actively supplied configurations.
