Westinghouse PC-500 PLC Interface CPU Processor Controller

The Westinghouse PC-500 PLC Interface CPU Processor Controller is a 24VDC programmable logic controller module with 2KB of memory, designed to run machine-control logic in industrial automation systems. It functions as a PLC CPU that executes control routines, coordinates automated production processes, and monitors input/output devices. With a 24VDC supply and a compact 2KB memory footprint, this unit is intended for industrial environments where reliable low-voltage logic processing is required. The PC-500 is mounted in control panels or on rack-based installations and uses a PLC I/O and control interface to connect sensors, actuators, and other control devices, enabling precise sequencing and logic processing in assembly lines, material handling, and packaging equipment. It is compatible with Westinghouse PLC ecosystems and is commonly chosen for retrofit, replacement, or maintenance of existing automation architectures. Common replacements include Allen-Bradley SLC 500 PLC processors, Siemens SIMATIC S5 CPUs, and Schneider Electric Modicon processors, reflecting its role as a compatible, low-power PLC CPU option in industrial automation and process control applications.
