DPC2K digital process controller

Emerson Systems November 15, 2023

Emerson has announced the release of its new 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 result is greatly improved closed-loop control and reliability, significantly reduced maintenance, improved safety, and superior environmental compliance. The DPC2K also provides numerous connectivity options, enabling remote setpoints, remote access for configuration, monitoring, and other features.

The DPC2K is designed to maintain its high level of performance for years with no required maintenance, and when maintenance is required, it is easily performed using modular replacement components. Another important advantage from this upgrade is the ability to easily interact with the DPC2K locally or remotely. Local interactions are performed via its menu-driven LCD and six-button user interface, with four buttons used for navigation and two for operator input.

The DPC2K has inputs, outputs, and intelligence to perform local closed-loop digital control using the proportional–integral–derivative (PID) controller. It can accept a 4-20mA input from a two-wire or four-wire instrument, typically the process variable (PV). For pressure control applications, an optional pressure sensor can be used to provide the PV.

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 to 80 °C.
