The Productivity3000 programmable automation controller combines features and capabilities of a PC-based control system with that of a typical programmable logic controller (PLC). The controller is a modular, rack-based system of up to 116,000 I/O points with local, expansion, and remote I/O bases and a full lineup of discrete, analog and specialty I/O modules. The CPU features 50Mb memory, fast scan times, and seven communication ports. Two power supplies (AC- and DC-powered) are available; both provide isolated 24VDC, 5VDC, and 3.3VDC to the product’s bases.
