DVC6200 and DVC6000 Digital Valve Controllers
1. Digital Valve Controller Setup
A. Electrical Power
Set the digital valve controller to PT-PT or MULTI-DROP.
For example, figure 1 shows the PT-PT/MULTI-DROP switch, which is located on the main electronics board, for the
DVC6200 HW2 digital valve controller.
Voltage ‐- ensure the switch is set in the “MULTI-DROP” position. The current will be fixed around 8.3 mA with a
24 V power source.
Milliamp current ‐- ensure the switch is set in the “PT-PT” position. Milliamp signal power to the instrument should
be set to a value between 6 and 20 mA.
Notes
Factory default is switch set to PT-PT.

For Multi-Drop and 24 V power a LC340 Line Conditioner may be required to ensure quality HART
For Point-to-Point and a milliamp powered system a HF340 HART filter may be required to ensure quality HART
