Fisher DVC6200 Digital Valve Controller with HART Communication Explosion Proof and Aluminum Alloy Housing

Product Overview

The Fisher DVC6200 is a digital valve controller that communicates via HART protocol. It accepts a two-wire 4-20 mA control signal and delivers a proportional pneumatic output to position a valve actuator. This unit is designed to replace analog positioners on most pneumatic actuators without requiring adapter hardware. A magnetic, non-contacting position sensor removes the need for a mechanical linkage, thereby eliminating wear and extending cycle life. The fully sealed electronics module is built to withstand high vibration, temperature fluctuations, and contaminated plant air.

Technical Specifications

Application Industry

The DVC6200 has demonstrated reliable performance in refining, chemical, nuclear, oil and gas, power, pulp and paper, food and beverage, water and wastewater, pharmaceutical, and metals and mining industries. It is used for controlling flow, pressure, temperature, and level loops.

Common Problems

• Instrument will not communicate: Check power supply, terminal voltage (should be 9–32 VDC), and wiring connectors on the printed wiring board.

• Valve does not stroke from 0 to 100%: Verify pneumatic connections and supply pressure; check that function block is in the correct mode.

• I/P converter output out of spec: May indicate a defective module base seal, defective relay, or a faulty 67CFR regulator.

Replacement Models

The DVC6200 is designed to retrofit existing analog positioner installations. It is a common upgrade from older DVC2000 units. For other brands, verify mounting, travel range, and communication protocol before ordering.
