Double‐Acting Actuators
DVC6200f digital valve controllers on double‐acting actuators always use relay A. With no instrument Fieldbus power
(Zero Power Condition) OUTPUT A is at 0 pressure and OUTPUT B is at full supply pressure when the relay is properly
adjusted. To have the actuator stem extend from the cylinder with increasing input signal, connect OUTPUT A to the
upper actuator cylinder connection. Connect OUTPUT B to the lower cylinder connection. To have the actuator stem
retract into the cylinder with increasing input signal, connect OUTPUT A to the lower actuator cylinder connection.
Connect OUTPUT B to the upper cylinder connection.
Special Construction to Support Solenoid Valve Testing
Note
Solenoid valve testing is only available for instrument level PD.
In single‐acting actuator applications with a solenoid valve installed, the DVC6200f can be configured to monitor the
health of the solenoid valve test, which is initiated by the Logic Solver. This is accomplished by connecting the unused
output port B from the DVC6200f to the pneumatic monitoring line between the solenoid valve and the actuator, as
shown in figure 2‐23. When single‐acting, direct relay C is installed, the “unused” output port is port B. When
single‐acting, reverse relay B is used, the unused port is port A.

Note
This application is called “special application” in the Setup Wizard relay selection.
This configuration is not possible with a double‐acting actuator or when using relay A in single‐acting mode.
