Relay Type—There are three categories of relays that result in combinations from which to select.
Relay Type: The relay type is printed on the label affixed to the relay body.
A = double‐acting or single‐acting
B = single‐acting, reverse
C= single‐acting, direct
Special App: This is used in single‐acting applications where the “unused” output port is configured to read the
pressure downstream of a solenoid valve.
Lo Bleed: The label affixed to the relay body indicates whether it is a low bleed version.
Zero Power Condition—The position of the valve (open or closed) when the electrical power to the instrument is
removed. Zero Power Condition (ZPC) is determined by relay type, as shown in figure 3‐2.

Travel Sensor Motion
WARNING
If you answer YES to the prompt for permission to move the valve when determining travel sensor motion, the instrument
will move the valve through a significant portion of its travel range. To avoid personal injury and property damage caused
by the release of process fluid or pressure, isolate the valve from the process and equalize pressure on both sides of the
valve or bleed off the process fluid.
