The Siemens S7-200 SMART ST60 is the highest I/O transistor-output CPU in the SMART series, designed for applications that demand fast digital control, extensive I/O capacity, and advanced communication capabilities. It features 36 digital inputs and 24 transistor outputs, all operating at 24 VDC. ST60 supports high-speed pulse output (up to 5 axes at 200 kHz) for precise motion and stepper motor control, making it ideal for positioning systems, multi-axis conveyors, and pick-and-place machines.

With built-in PROFINET Ethernet and RS-485 ports, it allows integration with industrial networks and HMI/SCADA systems. The CPU’s micro SD slot facilitates easy program backup and firmware management. Its real-time clock enables time-based operations and event logging. With a program memory of approximately 30 KB and fast processing speeds (0.15 μs per bit), the ST60 is a solid choice for demanding control tasks in smart factories and mid-range automation systems.
