Description
The 6ES7211-1AE40-0XB0 is a SIMATIC S7-1200 CPU 1211C compact controller with DC/DC/DC electronics, intended for compact machine and plant automation.

With six integrated 24 V DC digital inputs, four transistor 24 V DC digital outputs and two 0-10 V analog inputs, the 6ES7211-1AE40-0XB0 handles mixed control signals in one compact device. Its 20.4-28.8 V DC supply range and high-speed inputs and outputs support counting, pulse and positioning tasks.

The 6ES7211-1AE40-0XB0 provides 75 KB work memory, 1 MB integrated load memory and one 100 Mbit/s PROFINET interface with a single RJ45 port. Engineering requires STEP 7 V20 or higher, while PROFINET IO, S7 communication and open Industrial Ethernet functions support networked automation.

For installation, the 6ES7211-1AE40-0XB0 measures 90 x 100 x 75 mm, carries IP20 protection and is specified for horizontal operation from -20 to +60 °C. Siemens currently lists the article as a PM300 Active Product and has announced product phase-out from 1 November 2026, so confirm project version, I/O loading and expansion requirements when planning a new build or replacement.
