Fisher 67CFR Filter Regulator Fisher FIELDVUE DVC6200 Intelligent Digital Valve Controller Valve Positioners

The Fisher FIELDVUE DVC6200 is a HART-communicating digital valve controller that converts a 4-20 mA control signal into pneumatic output for actuators. It is designed for easy retrofit on existing analog positioners for Fisher and non-Fisher pneumatic actuators, enhancing control precision and reliability. The device features linkage-less non-contact position feedback to maximize cycle life and is built for harsh environments with fully encapsulated electronics. Firmware 7 introduces diagnostic enhancements without hardware changes, ensuring seamless upgrades from firmware 6 or older. The quick start guide covers installation on various actuators, including sliding-stem and rotary types, with options for SIS and FOUNDATION Fieldbus configurations.

• Linkage-Less Feedback: Non-contact system eliminates wear, maximizing cycle life.
• Built-to-Survive Design: Encapsulated electronics resist vibration, temperature, and corrosion; weather-tight terminal box isolates wiring.
• Accurate Performance: Two-stage positioner for quick response to large changes and precise control for small setpoints; travel control with pressure fallback.
• Ramped Cutoff: Smooth transition from throttling to shutoff for improved valve operation (firmware 7 enhancement).
• Enhanced Safety and Commissioning: HART access reduces hazardous exposure; fast loop commissioning locally or remotely.
• Diagnostic Improvements (Firmware 7): Better partial stroke testing, alert history, and solenoid valve health monitoring without hardware changes.
• Ease of Installation: Integral mounting on Fisher actuators; options for long-stroke and 180° rotary travel with special kits.

The DVC6200 is ideal for process industries such as oil & gas, chemical, and power generation, where precise valve control is critical. It supports throttling and on-off applications on sliding-stem linear and quarter-turn rotary valves. Suitable for safety instrumented systems (SIS) with partial stroke testing, and can be used in remote or hazardous locations for reduced maintenance exposure. Firmware 7 upgrades enhance diagnostics for predictive maintenance in existing installations.

1. How do I install the DVC6200? Follow the quick start guide: Mount on actuator (e.g., Fisher 657/667), connect wiring (4-20 mA loop, ground), supply air (1.4-10 bar), and calibrate using HART tools or local interface.
2. What changes with firmware 7 upgrade? No hardware changes; enhanced diagnostics like ramped cutoff, better partial stroke tests, and solenoid health monitoring. Update user interfaces like ValveLink or AMS Device Manager.
3. Can it be used in SIS applications? Yes, SIL 3 capable; configure for trip on low current/high current or pressure fallback.
4. What if position feedback fails? Automatically reverts to pressure control mode to maintain operation.
5. How to commission remotely? Use HART communication with tools like 475 Field Communicator or ValveLink software.
