Siemens 6ES7134-6JF00-0CA1 SIMATIC ET 200SP AI 8xRTD/TC 2-Wire HF 16-Bit Analog Input Module

The Siemens 6ES7134-6JF00-0CA1 is a SIMATIC ET 200SP analog input module (AI 8xRTD/TC 2-wire HF) with 8 channels for RTD and thermocouple sensors in 2-wire connection, 16-bit resolution, and +/-0.01% linearity error. It accepts Pt100/Pt1000/Ni100 resistance thermometers and thermocouple types B, C, E, J, K, L, N, R, S, T, and U.

Technical Specifications

Selection Notes

The 2-wire connection needs fewer terminal points than a 4-wire RTD module but does not compensate for lead resistance -- use it when cable runs are short relative to the sensor's own resistance, and step up to the 4-wire HF variant in the same family for long runs or high-accuracy Pt100 measurement. Four independently parameterizable reference-channel groups let one module mix thermocouple types across channels without rewiring the temperature-compensation source group by group. The 200 m shielded cable length drops to 50 m for thermocouples, a limit worth checking against actual sensor routing before specifying this module on a large distributed station.

Applications

Process temperature monitoring in furnaces, extruders, and tanks; RTD and thermocouple measurement on ET 200SP distributed I/O stations; thermal process validation and calibration checks where multiple sensor types share one rack position.
