Siemens 6ES7211-1BE40-0XB0 Compact CPU AC/DC/Relay
An AC-powered S7-1200 compact CPU with six digital inputs, four relay outputs and two analog inputs.
Product Profile
Siemens 6ES7211-1BE40-0XB0 is the AC/DC/relay execution of the SIMATIC S7-1200 CPU 1211C.
Its integrated signal set comprises six 24 VDC digital inputs, four relay outputs rated 2 A and two 0–10 VDC analog inputs. Siemens specifies an 85–264 VAC, 47–63 Hz supply and 75 KB program/data memory.
This identity must not inherit wiring assumptions from the DC/DC/DC version. Mains isolation, relay load category, suppression, project backup and network settings require their own evidence.
Engineering Data
System Architecture
Mains-powered compact controller
The CPU accepts the published AC input range without a separate 24 VDC CPU supply.
Relay output flexibility
Four relay contacts serve documented AC or DC loads within the approved ratings and switching duty.
Integrated analog observation
Two 0–10 VDC inputs support compact measurement tasks defined by the project.
Controlled software baseline
Firmware, TIA Portal version and the downloaded project remain part of the service boundary.
Compatibility & Service
Separate mains and field evidence
Record the AC source, branch protection, PE arrangement and 24 VDC input supply before touching 6ES7211-1BE40-0XB0.
Characterize the relay loads
Capture load voltage, current, utilization, inrush, suppression and switching frequency for all four contacts.
Recommission deliberately
Restore the approved project, then prove input supply, relay behavior, analog channels, communications and safety interlocks.
Applications
Compact AC-fed panels
Controller replacement where the cabinet provides the published mains supply range.
Mixed-load relay switching
Operating documented contactor, solenoid or signaling loads within relay limits.
Legacy machine support
Maintaining a CPU 1211C project with exact I/O, network and firmware records.

FAQ
Can 6ES7211-1BE40-0XB0 use the same panel wiring as 6ES7211-1AE40-0XB0?
No. The AC supply and relay-output execution have different power and load interfaces from the DC/DC/DC CPU.
What should be recorded for each relay on 6ES7211-1BE40-0XB0?
Record load voltage, steady and inrush current, utilization category, suppression, switching rate and required safe state.
Which software evidence belongs with a 6ES7211-1BE40-0XB0 spare?
Provide the TIA Portal project, engineering version, CPU firmware, device name, IP settings and accessible diagnostic buffer.
Is a CPU 1212C AC/DC/relay a drop-in replacement for 6ES7211-1BE40-0XB0?
No. The larger CPU has different onboard I/O and memory and requires project, wiring and physical-fit review.
What acceptance tests suit 6ES7211-1BE40-0XB0?
Verify mains and 24 VDC circuits separately, then test six inputs, four relay outputs, both analog inputs, communications and machine interlocks.
