Emerson (Marshalltown, Iowa) announced its Fisher FIELDVUE DPC2K digital process controller (DPC2K).

The DPC2K can be retrofitted to Fisher Wizard pneumatic controllers and to pneumatic controllers from other manufacturers. The DPC2K also provides numerous connectivity options, enabling remote setpoints, remote access for configuration, monitoring and other features.

Features:

  • Able to be retrofitted as direct replacement for pneumatic controllers installed on most valves, regardless of manufacturer
  • Configurable loop types
  • Over 150 units of supported measure
  • 20 times-per-second (50 milliseconds) scan and update rates
  • Configurable dead band
  • Anti-reset windup
  • Dynamic reset limiting
  • Designed to maintain high level of performance for years with no required maintenance
  • Maintenance performed using modular replacement components
  • Ability to interact with DPC2K locally or remotely
  • Inputs, outputs and intelligence to perform local closed-loop digital control using proportional–integral–derivative (PID) controller
  • Able to accept 4-20mA input from two-wire or four-wire instrument
  • Optional pressure sensor to provide PV

Fisher LoopConnect software provides the most comprehensive remote access, including configuration and monitoring, networked or direct Ethernet connection, and alerts for troubleshooting. Options include integral, sealed gauge pressure sensor with 0-30, 0-100, 0-300, 0-600 or 0-1500 pounds-per-square-inch range and pneumatic output with low bleed of less than 3.0 standard cubic feet per hour.

Because the DPC2K is configurable, the same base model can be used in a variety of applications, including but not limited to pressure, flow, level, temperature, percentage, volume and rate control. The DPC2K is rated for use in Class 1 Division 1 or Zone 1 hazardous areas and it has an operating temperature range of -40-80 degrees Celsius. Inputs of 9-28 volts direct current are accommodated, with a typical power draw of only 1 watt.
