Product details

PROFINET CPU with 1 MB work memory

The Siemens 6AG1212-1BE31-4XB0 is an S7-1200 CPU with a PROFINET interface and 1 MB of integrated work memory. The 24 V DC supply accepts 20.4 V to 28.8 V, covering the typical industrial 24 V rail with brownout headroom.

Programming languages and I/O addressing

Programmable in FBD, LAD, and SCL — the three IEC 61131-3 languages cover sequential logic, function-block diagrams, and structured text. The CPU addresses 1,024 bytes each of inputs and outputs, enough for a medium-size machine cell with distributed I/O.

Environmental range and panel fit

The 90 mm wide, 100 mm high, 75 mm deep footprint clips onto a standard DIN rail — the same slot as any S7-1200 CPU, no extra panel space needed.
