The Siemens SIMATIC S7-200 SMART CPU CR60 AC/DC/Relay PLC (Part Number: 6ES7288-1CR60-0AA0) is a compact programmable logic controller designed for industrial automation, machine control, and manufacturing applications. This controller integrates an AC power supply, 24 V DC digital inputs, and relay outputs in a single unit, providing a practical solution for industrial systems that require multiple digital signals and relay-based switching.

The CR60 features 36 digital inputs rated at 24 V DC and 24 relay outputs rated up to 2 A under specified load conditions. It operates from an AC supply ranging from 85 to 264 V AC at 47–63 Hz. The controller provides 20 KB of program and data memory and supports programming through Siemens STEP 7 Micro/WIN SMART software.

The digital inputs can monitor compatible industrial sensors, push buttons, selector switches, limit switches, and other field devices. The relay outputs can switch compatible electrical loads within the manufacturer's specified voltage, current, and load-type limits. This integrated configuration can help simplify control-panel design and reduce the need for separate digital I/O modules in suitable applications.

The Siemens S7-200 SMART CR60 supports Ethernet and RS-485 communication for integration with compatible HMIs, engineering systems, and industrial automation devices. Supported Ethernet communication functions include TCP/IP, while specific protocol capabilities depend on the product configuration and applicable documentation. The controller also supports functions such as high-speed counting and PID control when properly configured.

This PLC is suitable for packaging machinery, conveyor systems, assembly lines, manufacturing equipment, material-handling systems, and industrial control panels. Its compact design, onboard digital I/O, and relay-based outputs make it suitable for automation applications requiring dependable programmable control.
