Fisher DVC6200 Digital Valve Positioner with HART 4-20mA Aluminum Alloy Explosion Proof for Pneumatic Actuators

Product Overview

The Fisher DVC6200 is a digital valve controller that communicates via HART protocol. It takes a two-wire 4-20 mA signal and converts it to a pneumatic pressure output to drive a valve actuator. The unit is designed as a drop-in replacement for analog positioners on most pneumatic actuators. A non-contact, linkage-free position feedback system removes all rubbing parts, which dramatically extends cycle life. The fully potted electronics stand up to vibration, temperature fluctuations, and aggressive plant air.

Technical Specifications

Application Industry

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

Common Problems

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

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

• I/P converter output out of specification: possible defective 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, confirm mounting, travel, and protocol compatibility before ordering.
