FOXBORO 762CNA Single-Station Microprocessor PID Controller

Product Description

FOXBORO 762CNA is a single-station MICRO® microprocessor PID controller of Foxboro 762C series, a panel-mounted process control instrument. It supports two independent PID control loops and adopts Foxboro patented EXACT auto-tuning algorithm. It can perform cascade control, auto-selector control, split-range output, ratio control, batch control, totalization and comprehensive calculation. Equipped with fluorescent backlit display and keypad operator interface, it can display bar graph, digital reading, loop tag and alarm information simultaneously. Bumpless auto/manual transfer is supported. It is widely deployed for single-loop or dual-loop regulation in chemical, power, oil & gas and other process industries. It can be panel flush mounted or mounted on Foxboro shelf rack.
