Siemens SIMATIC S7-200 SMART EM AI04 Analog Input Module (6ES7288-3AE04-0AA0)

Description

The Siemens 6ES7288-3AE04-0AA0 EM AI04 expansion module expands the signal processing capability of SIMATIC S7-200 SMART CPU systems. It allows the PLC to interface directly with 4 analog field sensors, providing reliable data conversion for industrial monitoring and control loops.

Main Features

This expansion module provides 4 configurable analog input channels that support standard industrial voltage ($\pm2.5\text{ V}$, $\pm5\text{ V}$, $\pm10\text{ V}$) and current ($0\text{ to }20\text{ mA}$, $4\text{ to }20\text{ mA}$) signal ranges. Featuring a 12-bit plus sign resolution, it ensures accurate measurement of process variables. The module connects directly to the CPU side expansion bus interface.

Benefits

Integrated analog signal processing allows precise monitoring of physical parameters without requiring external signal signal converters. Its compact design saves cabinet space on standard DIN rails. Fast integration with STEP 7-Micro/WIN SMART programming software simplifies setup and parameterization.

Applications

The EM AI04 module is used across small-to-medium industrial automation systems requiring analog signal acquisition. Typical applications include pressure monitoring, temperature sensing, level control, flow measurement, and speed feedback in manufacturing and process plants.
