Siemens 6ES7212-1BE40-0XB0 Compact CPU AC/DC/Relay
A SIMATIC S7-1200 compact CPU with AC supply, eight digital inputs, six relay outputs and two analog inputs.
Product Profile
Siemens 6ES7212-1BE40-0XB0 is a CPU 1212C configured as AC/DC/relay for SIMATIC S7-1200 automation.
The official product description specifies eight 24 VDC digital inputs, six 2 A relay outputs and two 0–10 VDC analog inputs. The controller operates from 85–264 VAC at 47–63 Hz and provides 100 KB program/data memory.
Compared with the smaller 1211C, this model has a different onboard I/O count and memory capacity. Any substitution therefore requires project and wiring review rather than family-name matching.
Engineering Data
System Architecture
Expanded local I/O
Eight digital inputs and six relay outputs provide a larger onboard set than CPU 1211C.
AC panel integration
The CPU power stage accepts the manufacturer-published mains range.
Contact-based outputs
Relay points support documented loads after current, inrush and suppression review.
100 KB program/data space
The published memory capacity must be considered when evaluating a migration or replacement CPU.
Compatibility & Service
Map the ten inputs
Record the eight digital points and two analog ranges, including commoning and field supply.
Profile six relay loads
Capture current, inrush, switching duty, suppression and safe state for each output on 6ES7212-1BE40-0XB0.
Prove the full controller
Verify power, project startup, all onboard I/O, expansion hardware, network paths, time and retained values.
Applications
Standalone machine controller
Coordinating moderate local I/O in an AC-powered control panel.
Relay-based actuator control
Switching approved field loads where contact behavior and suppression are documented.
Capacity-aware replacement
Maintaining the exact 1212C hardware boundary when project size and I/O schedule matter.

FAQ
How does 6ES7212-1BE40-0XB0 differ from the CPU 1211C AC/DC/relay model?
It has eight digital inputs, six relay outputs and 100 KB program/data memory, so the I/O and project boundary is different.
What information prevents an incorrect 6ES7212-1BE40-0XB0 replacement?
Provide the complete MLFB, firmware, TIA Portal project, onboard I/O schedule, expansions, network settings and supply record.
Are all six relay outputs on 6ES7212-1BE40-0XB0 suitable for the same load?
Not automatically. Each load needs its own voltage, current, inrush, utilization and suppression review.
What should be checked before migrating to or from 6ES7212-1BE40-0XB0?
Compare memory use, onboard point addresses, output technology, expansion limits, firmware and physical panel wiring.
Which tests close a 6ES7212-1BE40-0XB0 service report?
Document normal startup, project checksum, ten input checks, six output tests, communications, diagnostics and every affected interlock.
