Description

Siemens CPU 1212C AC/DC/relay combines power supply, processing, memory and I/O in a 70‑mm‑wide housing. It accepts 120/230 V AC supply within the 85–264 V range at 47–63 Hz and consumes around 70 mA at 120 V or 38 mA at 240 V; maximum currents are 330 mA and 200 mA respectively. Inrush current can reach 20 A and typical power loss is 4 W. Program memory is 150 kB and data memory 500 kB with 650 kB work memory; load memory of 8 MB can be expanded via memory card up to 32 GB. Processing times are extremely fast: 37 ns for bit operations, 30 ns for word operations and 74 ns for floating‑point instructions. The CPU supports up to 4 000 OB/FB/FC/DB/UDT blocks and provides 20 kB retentive data, 8 kB flag memory and 64 kB local data per priority class. Onboard I/O includes 8 digital inputs (24 V DC) with sink/source configuration and 6 relay outputs rated 2 A with 10 ms switching delay. Two RJ45 ports support PROFINET IO Controller/Device, IPv4, SIMATIC communication and open IE protocols at 100 Mbit/s. The module permits up to six expansion modules, features an integrated real‑time clock with 480‑h backup and ±2 s/day accuracy, and operates from −20 °C to +60 °C.
