FLOW FEEDBACK (DUAL VOLTAGE) ASSEMBLY
The new dual voltage Flow Feedback card receives the valve
potentiometer (V-Pot) signal representing the actual valve flow, and
provides a scaled output or flow feedback signal ranging between 0 10 Vdc that represents the signal received.
The flow feedback card has been a key component of the analog
product line for many years. The new feedback card can be powered
by either the original DC voltage used on the analog product, or it
can be powered by 24 Vac for use with the Celeris platform.
Originally developed for use with BEV/BSV valves, the flow
feedback signal is used to provide flow values for those valves that are
non-electronic. The flow value is then used in calculations for room
or zone balance.
The base-line functionality of the new flow feedback card is the same
as in the previous version. However, with a dual voltage option the
new card is ideal for use with both Celeris and analog systems.

FLOW FEEDBACK ASSEMBLY—1 OF 2
FEATURES
Phoenix Controls dual-voltage flow feedback boards can be used in parallel, or the board can be used as a replacement as
follows:
Phoenix Part Number
Notes
PRT-800-000-013LF
Replaces PRT-800-000-006 DC only and the combination of PRT-109-900-153LF AC to DC power converter and PRT-800-000-006.
APPLICATIONS
Phoenix Controls flow feedback cards are used for airflow control requiring two-position valves. The flow feedback cards
provide the functionality necessary for velocity control to maintain a constant velocity as the volume of air flow varies. A
change in the air flow causes the card to drive its valve to one of two pre-set positions.
INSTALLATION
The flow feedback assembly is factory installed in the PPC flame retardant black box part number 520-000-011LF. One PCB
required per flow feedback assembly.
