Siemens 6ES7 288‑3AE08‑0AA0 EM AE08 S7‑200 SMART Analog Input Module
Product Overview
The Siemens 6ES7 288‑3AE08‑0AA0 EM AE08 is an analog input expansion module designed for the S7‑200 SMART PLC series. It extends the analog signal acquisition capability of S7‑200 SMART CPU controllers. This module collects analog signals from field sensors and transducers, converts analog physical signals into digital data that the PLC can process, and transmits data to the main CPU via the internal expansion bus. It is widely used in industrial automation scenarios such as temperature measurement, pressure monitoring, flow detection, liquid‑level acquisition, and analog parameter collection for mechanical equipment. As a genuine original Siemens expansion module, it features compact structure, reliable industrial‑grade performance, and seamless hardware compatibility with S7‑200 SMART CPUs.
Main Functions
- Analog signal acquisition: Receive standard analog voltage and current signals from on‑site field instruments and sensors.
- Analog‑to‑digital conversion: Convert continuous analog input signals into discrete digital values for PLC logic calculation and program processing.
- Channel diagnosis: Support basic channel fault detection, including open‑circuit detection for sensor wiring faults.
- Bus data interaction: Communicate with S7‑200 SMART CPU through the internal expansion backplane bus, no additional communication wiring is required.
- Signal range configuration: Adapt to multiple common industrial analog signal types through software parameter configuration in programming software.
- Isolation protection: Provide electrical isolation between field analog circuits and PLC internal logic circuit to reduce interference from field noise.
