Siemens 6ES7534-7QE00-0AB0 SIMATIC S7-1500 AI 4xU/I/RTD/TC AQ 2xU/I ST PLC I/O Module

The Siemens SIMATIC S7-1500 6ES7534-7QE00-0AB0 (AI 4xU/I/RTD/TC/AQ 2xU/I ST) is a universal analog module combining 4 analog inputs configurable for voltage, current, resistance/RTD, or thermocouple measurement with 2 analog outputs for voltage or current, at 16-bit resolution and 0.3% accuracy. It supports reparameterization and calibration in RUN (CiR) and mounts in a 35 mm S7-1500 backplane slot.

Technical Specifications

Selection Notes

ST in the designation marks the standard-accuracy variant of this universal module - it accepts voltage, current, RTD/resistance, and thermocouple inputs on the same 4 channels, configured per channel rather than simultaneously in all modes, so one module replaces separate dedicated AI modules when a machine mixes sensor types across a small number of measurement points. Reparameterization and calibration are possible in RUN (CiR), which matters for machines that cannot be stopped to add or recalibrate a sensor channel. The 2 integrated analog outputs mean small closed-loop control, such as a valve positioner, does not need a separate AQ module alongside this one.

Applications

Used for mixed-sensor process measurement - temperature via RTD/TC, pressure or level via 4-20 mA, and position feedback via 0-10 V - combined with 2 analog control outputs on process skids, utilities, and machine sections where sensor types vary point to point.
