Siemens 6ES7134-6GD01-0BA1 SIMATIC ET 200SP AI 4xI 2-/4-Wire ST 4AI 16-Bit Remote I/O Module

The Siemens 6ES7134-6GD01-0BA1 is a SIMATIC ET 200SP analog input module with 4 current-input channels, switchable between 2-wire and 4-wire transducer connection, resolving 16 bit including sign. It mounts on a Type A0 or A1 BaseUnit and holds basic accuracy within ±0.3% of the input range at 25 °C.

Technical Specifications

Selection Notes

Wire-break diagnostics only work in the 4-20 mA range, since a 0-20 mA loop can't distinguish a broken wire from a genuine zero reading - pick the 4-20 mA range on any channel where loop integrity matters. The module accepts both 2-wire (loop-powered) and 4-wire (self-powered) transmitters on the same channel set, so mixed transducer types can share one module instead of splitting across separate 2-wire and 4-wire input modules. At ±0.3% basic error and 16-bit resolution, it suits process measurements like 4-20 mA pressure or flow transmitters where a coarser module wouldn't resolve small setpoint changes.

Applications

Reads 4 analog current loops - pressure transmitters, flow meters, temperature transmitters with 4-20 mA output - into a SIMATIC ET 200SP station, with wire-break and short-circuit diagnostics reported to the PROFINET or PROFIBUS controller.
