Siemens 6ES7215-1BG40-0XB0 SIMATIC S7-1200 CPU 1215C AC/DC/RLY 14DI/10DO/2AI/2AO Programmable Logic Controller

The Siemens SIMATIC S7-1200 CPU 1215C (6ES7215-1BG40-0XB0) is a compact AC/DC/relay CPU with 200 KB integrated program memory, 14 onboard 24 V DC digital inputs, and 10 relay outputs rated 2 A. Two isolated PROFINET ports with an integrated switch support IO-controller and IO-device operation, PROFINET line topologies, and OPC UA server access without an additional communication module.

Selection Notes

Within the S7-1200 CPU line, the 1215C's onboard 2 AI / 2 AO removes the need for a separate analog signal board on projects that need light analog I/O alongside 14 DI / 10 DO, leaving the signal-board slot free for later expansion. The relay outputs on this variant switch AC or DC loads directly at up to 2 A per point without an external interposing relay, which suits mixed-voltage panels; where PWM or a switching rate above the relays' mechanical limit is needed, a DC-input/transistor-output variant is the better fit. Two isolated PROFINET ports with an integrated switch let this CPU sit inline in a line topology without an external switch, and 16 connectable IO devices cover most single-CPU machine cells.

Applications

Compact machine-control cells that need mixed digital/analog I/O without add-on modules - packaging, material handling, and utility or HVAC skids wired for direct AC actuator switching. The six HSC-capable inputs (up to 100 kHz single-phase) support incremental-encoder or flow-meter pulse counting on the same CPU. PROFINET IO controller/device operation plus OPC UA server access covers both machine-level I/O expansion and higher-level SCADA/MES data exchange from one CPU.
