De-Energize to Trip (DETT) DVC6200 SIS,
no Solenoid Valve
In a typical deenergize to trip application without a solenoid valve, the logic solver trip signal deenergizes the digital
valve controller to 4 mA (or 0 VDC). This drives the digital valve controller to the no output pressure condition. As a
result, the safety valve moves to its noair, fail safe position.

1. If the DVC6200 SIS is powered with 420 mA, connect the logic solver output card +/ terminals to the
corresponding DVC6200 SIS LOOP +/terminals.
Note
For the digital valve controller to operate with a 420 mA control signal the DIP switch must be in the pointtopoint loop position,
as shown in table 2. The control mode must be set to analog. This is set at the factory when ordered properly.
