What this CPU is
The Siemens 6AG1211-1AD30-4XB0 is a SIPLUS S7-1200 CPU 1211C DC/DC/DC controller built for extended temperature environments. It supports programming in FBD and LAD, takes a 20.4 to 28.8 V DC supply, and operates from -40 to 70 °C. Integrated Ethernet TCP/IP handles program download and communication as a server.
Extended temperature range
Rated for -40 to 70 °C, this CPU can be installed in unheated cabinets, cold storage areas, or outdoor enclosures without additional heating or cooling. The 20.4 V dropout threshold gives headroom for voltage sags on long DC runs.
Approvals
Carries CE mark, cULus, and UL approval, simplifying panel certification in North American and European markets.
