Siemens 6ES7134-6TD00-0CA1 SIMATIC ET 200SP AI 4xI 2-Wire HART Analog Input Module

The Siemens 6ES7134-6TD00-0CA1 is a SIMATIC ET 200SP analog input module with 4 HART-capable channels for 2-wire 4-20 mA transmitters, delivering 15-bit-plus-sign resolution and channel-by-channel diagnostics. It mounts on BU type A0 or A1 base units, runs from a 24 V DC supply (19.2-28.8 V range), and supports reparameterization while the station is in RUN.

Selection Notes

The HART channel support is the reason to pick this module over a standard ET 200SP AI 4xI without HART: it reads the superimposed HART signal from 2-wire loop-powered transmitters for diagnostics and remote configuration while still delivering the process value through the normal 4-20 mA path. Reparameterization in RUN means channel ranges and smoothing can be adjusted without pulling the station out of service, which matters when a HART transmitter needs to be recalibrated on a live line. The BU type A0/A1 requirement fixes the base unit choice at station design time, so confirm the BaseUnit slot before ordering.

Applications

Fits ET 200SP distributed I/O stations that read HART pressure, flow, level, or temperature transmitters and need channel diagnostics (wire break, short-circuit) reported back to the controller without separate HART multiplexer hardware.
