Siemens 6ES7215-1HG40-0XB0 S7-1200 CPU 1215C DC/DC/Relay 14DI/10DQ/2AI/2AO Programmable Logic Controller

The Siemens 6ES7215-1HG40-0XB0 is a SIMATIC S7-1200 CPU 1215C DC/DC/relay compact controller with 14 DI 24VDC, 10 relay DO rated 2A, 2 analog inputs, 2 analog outputs, and 2 integrated PROFINET ports. It runs on 20.4-28.8 V DC supply, holds 200 KB of program/data memory, and processes bit operations in 0.08 microseconds typical.

Selection Notes

Relay outputs (10x, 2A, 30W DC / 200W AC) handle mixed DC and AC loads directly without transistor-output current limits, at the cost of slower switching and finite mechanical life - 100,000 cycles at rated load, 10 million mechanically - so it isn't the choice for high-frequency PWM outputs. The onboard 2 AI/2 AO pair covers a basic process loop with one sensor and one actuator without adding a signal board; larger loop counts still need SM 1231/1232 expansion modules. Two integrated PROFINET ports with switch functionality let the CPU sit in a line topology without a separate switch, useful on machines wired point-to-point along the frame.

Applications

Standalone machine control or small-cell automation needing mixed DC/relay I/O and a basic analog loop on one CPU - conveyor sections, packaging cells, and utility skids where a compact S7-1200 replaces a full S7-1500 station.
