Transistor Output CPU Module for S7-200 SMART:Model ST20, a 24 V DC transistor-output CPU in the SIMATIC S7-200 SMART series—ideal for applications requiring high-speed switching, fast response, or motion control, such as small packaging machines, feeders, dispensing systems, and automation cells.
Supports High-Speed Pulse Output (PTO/PWM):All 8 outputs support high-speed pulse generation up to 100 kHz.Supports PTO (Pulse Train Output) and PWM (Pulse Width Modulation)—can directly control stepper or servo drives for precise positioning and speed regulation.
Built-in Real-Time Clock (RTC):Features an integrated real-time clock—supports time-stamping, scheduled operations, and data logging without additional hardware.
Seamless Integration with STEP 7-Micro/WIN SMART:Programmed and monitored using STEP 7-Micro/WIN SMART software—supports LAD, FBD, and STL programming languages—user-friendly interface with high engineering efficiency.
