Wiring Analog and Digital Outputs
FBVI-2U4-4T
has 4 digital outputs and 2
UniPuts™
(normally configured as analog outputs) for
controlling a wide variety of possible elements of the VAV box. The
FBVI-2U4-4T
includes integrated
damper control. It is possible to control single speed and variable speed fans (both parallel and series),
electric heat, proportional heating valves, and tri-state heating valves depending on the application.
•
DO-09
can be configured for controlling first stage on-off electric heat or to open a tri-state
heating valve.
•
DO-10
can be configured for controlling the second stage on-off electric heat or to close a tri-state
heating valve.
•
DO-11
can be configured for controlling third stage on-off control.
•
DO-12
can be configured for constant volume series or parallel fan on-off control.
•
AO-14
can be configured for controlling any first stage modulating heating valves,
SCR
(
Silicon
Controlled Rectifier
), or E
MC
(
Electronic Modulating Control
) type controls depending on the heating
elements of the VAV box.
•
AO-15
can be configured for controlling any second stage modulating heating valves, SCR (
Silicon
Controlled Rectifier
), or
EMC
(
Electronic Modulating Control
) type controls depending on the heating
elements of the VAV box. This output can also be configured for variable speed fan control (series
or parallel).
Note:
AO-14
and
AO-15
are preconfigured as a 0
…
10 V DC direct-acting output. During configuration,
it is possible to configure either output or both outputs for reverse acting or 10
…
0 V DC. Either
or both of these outputs can also be configured for 2
…
10 V DC
or 10
…
2 V DC.
