Siemens SIMATIC S7-200 SMART Analog Input Module About

The Siemens 6ES7288-3AE04-0AA0 is an active, compact SIMATIC S7-200 SMART analog input expansion module (EM AI04). It is engineered to capture high-precision process variables in small-to-medium industrial automation networks. This module expands your PLC configuration by adding four analog inputs with a high-resolution 11-bit performance (plus sign bit) for voltage or 12-bit for current measurements.Designed for versatile field instrumentation, each channel can be individually configured to read standard industrial signals, including voltage (10V, 5V, 2.5V) or current (020 mA, 420 mA). Housed in a dense, IP20-protected enclosure meant for standard DIN rail mounting, it operates reliably with a low typical power loss of just 1.5W. The module includes diagnostic monitoring for limit violations and features front-facing status LEDs for swift troubleshooting of sensor loops.
