Description

The Siemens SR60 is the top-tier relay-based CPU in the S7-200 SMART family. It includes 36 digital inputs and 24 relay outputs, supporting high-volume control logic across a wide range of applications. It features built-in PROFINET and RS-485 communication interfaces, enabling easy connectivity with field devices, HMIs, drives, and higher-level controllers. This model is equipped for high-speed pulse output (up to 5 axes, 200 kHz) and high-speed counters, supporting complex motion and positioning applications. Relay outputs ensure electrical isolation and are ideal for mixed AC/DC load switching. Program memory of approximately 30 KB supports extensive logic and function blocks. Signal boards allow analog input/output and serial expansion. SR60 is ideal for elevator control, batching, large-scale lighting, and OEM packaging systems. Its robust structure, high I/O count, and multiple network options make it a strong choice for industries requiring both power and precision.
