Siemens 6ES7211-1BE40-0XB0 is a SIMATIC S7-1200 CPU 1211C AC/DC/relay compact controller with integrated digital and analog I/O plus one PROFINET interface.
The controller provides six 24 V DC digital inputs, four relay outputs, two 0 to 10 V DC analog inputs, 75 KB work memory, and 1 MB integrated load memory. Engineering requires STEP 7 V20 or higher.
The CPU is intended for compact industrial automation tasks that require local I/O, relay switching, analog signal acquisition, and Ethernet-based communication.
Use 6ES7211-1BE40-0XB0 within a SIMATIC S7-1200 configuration engineered for its AC supply, 24 V DC input circuits, relay output loads, analog input ranges, and PROFINET network. Confirm supported signal boards, communication modules, and SIMATIC memory cards in the current Siemens hardware catalog.
Replacement or migration requires verification of the TIA Portal project, firmware compatibility, terminal assignments, relay load characteristics, enclosure conditions, grounding, and EMC design. Do not substitute another CPU 1211C order number solely on the basis of housing size.
Confirm current Siemens product availability and lifecycle status for article number 6ES7211-1BE40-0XB0 before procurement. Installed units should remain under the documented electrical, environmental, firmware, and maintenance conditions.
For replacement, compare the complete article number, CPU type, AC supply range, relay output ratings, onboard I/O, firmware, project compatibility, and PROFINET configuration. Back up the validated project and follow controlled Siemens migration and commissioning instructions.
