Product Description
DVC2000 is Fisher FIELDVUE digital valve controller (smart valve positioner) from Emerson. It adopts hall‑effect linkage‑less non‑contact position feedback to eliminate mechanical linkage wear failures, suitable for linear and rotary pneumatic actuators. It supports 4‑20 mA analog signal plus HART communication. Built‑in LCD local keypad interface for on‑site configuration, calibration and parameter setup. Combined with ValveLink software, it enables online valve diagnostics, travel deviation monitoring, cycle counting and performance test. Four function levels AC/HC/AD/PD are available. Optional integrated limit switches and valve position transmitter output. Multiple hazardous‑area approvals, IP66 / NEMA4X enclosure rating. Succeeded by DVC6200 series
