Fisher DVC6200 Digital Valve Controller with HART Communication and 4-20mA Control Signal in Aluminum Alloy Housing

Product Overview

The Fisher DVC6200 is a digital valve controller that communicates over HART. It takes a two-wire 4-20 mA control signal and produces a pneumatic output to move a valve actuator. The unit is engineered to replace analog positioners on most pneumatic actuators without adapter parts. Its magnetic, non-contacting position sensor removes linkage wear and extends cycle life. The encapsulated electronics module withstands high vibration, temperature swings, and contaminated plant air.

Technical Specifications

Application Industry

The DVC6200 is used in refining, chemical, nuclear, oil and gas, power generation, pulp and paper, food and beverage, water and wastewater, pharmaceutical, and metals and mining. It controls flow, pressure, temperature, and level loops.

Common Problems

• No communication: check power supply, terminal voltage (9–32 VDC), and wiring on the printed wiring board.

• Valve does not fully stroke: inspect pneumatic tubing and supply pressure; ensure function block is in the correct mode.

• I/P converter output out of specification: possible faulty module base seal, relay, or 67CFR regulator.

Replacement Models

The DVC6200 retrofits existing analog positioner installations and is a common upgrade from the DVC2000. For other brands, verify mounting, travel, and protocol compatibility before ordering.
