What are Controllers - Programmable (PLC, PAC) ?
Controllers - Programmable (PLC, PAC) are electronic devices designed to automate and control industrial processes through programmable logic. They are widely used in applications such as production electronics assembly, maintenance, and field replacement. Key specifications for selection include Communications, which ensures compatibility with existing systems; Memory Size, which affects the complexity of the programs that can be run; and Number of Inputs and Type, which determines the range of devices that can be controlled. Sourcing teams should validate lifecycle status and consider alternate-source options to mitigate procurement risks.
