Product details

Part summary and fit notes

The Siemens 6ES7214-1HG31-0XB0 is a SIMATIC S7-1200 CPU 1214C DC/DC/DC controller that accepts a 24 V DC supply over a 20.4–28.8 V range, tolerating plant DC bus dips without a separate regulator. Rated ambient from -40 to 70 °C, it sits comfortably in outdoor cabinets or unheated enclosures. The onboard 4 Mbyte integrated memory holds the user program and retains data via 480 h typical backup time on the internal capacitor, enough for extended power outages. This unit carries cULus, CE, FM, UL, and CSA approvals — a full compliance package for North American and EU panels without extra certification effort.

Connectivity and programming

Built-in PROFIBUS, Modbus TCP, UDP, and AS-Interface cover most fieldbuses without add-on comm modules. The CPU also supports FBD, LAD, and SCL programming languages. I/O addressing is 1 024 bytes each for inputs and outputs. Forcing of I/O and variables is supported.

Frequently asked questions

What compliance documentation does this CPU carry?

The 6ES7214-1HG31-0XB0 is listed with cULus, CE, FM, UL, and CSA approvals. Declaration of conformity and CE marking documentation are available upon request — the approvals are factory-original, not regional re-certifications.
