Technical Highlights: The CPU 222 AC model excels in applications requiring moderate I/O counts with relay isolation. Its PROFIBUS DP expansion capability allows integration into larger Siemens networks, while the onboard high-speed counters and pulse outputs support simple motion control tasks. The relay outputs are rated for 2A at 250 V AC or 30 V DC, making them suitable for switching small motors, valves, and indicator lights directly without external interface relays. All inputs are optically isolated and support 24 V DC sensors with configurable filtering for noise immunity. The unit is fully compatible with STEP 7-Micro/WIN programming software, offering ladder logic, function block diagram, and statement list editors.
