INTRODUCTION
◆
◆
The
HPO-6704
converts a standard analog
voltage output to a
4–20 mA output
while
providing an adjustable potentiometer for
override settings while in the “Hand” position.
NOTE:
The
HPO-6704 board supplies the
power
and will not work with a 4–20
mA device that also supplies its own
power.
Each output board has a red
LED
indicator that
turns On when the board’s output is turned
On
either manually or automatically.
Output boards have an accessible three-position
slide switch
for selecting the
“Hand-Off-Auto”
functions:
◆
◆
While in the
H (“Hand” or manual On)
position,
the output is manually energized, and the
controller is provided with a feedback signal to
indicate the output has been overridden.
◆
◆
While in the
O (Off)
position, the output is
manually de-energized, and the controller is
provided with a feedback signal to indicate the
output has been overridden.
◆
◆
While in the
A (Auto)
position, the output is
under the command of the controller.
NOTE:
An HPO-670x
-1
is always in auto mode
and does not have the manual slide
switch.
NOTE:
HPO-6701
triac
and HPO-6703/6705
relay
circuits use the Switched
Common
SC
terminal—
not
the Ground
Common
GND
terminal.
NOTE:
HPO-6701
triac
outputs are for 24 V
AC
only.
NOTE:
Only the HPO-670
1
triac and HPO-
670
4
4–20 mA boards are approved
for
smoke control
applications. For
smoke control application information,

For enhanced controller output options (such
as manual control, using large relays, or for
devices that cannot be powered directly from a
standard output), install output override boards
(in compatible controllers). The following
types of
override boards
are available:
◆
◆
The
HPO-6702
enhances the analog
voltage
output
with a
“Hand-Off-Auto” control
while
providing an adjustable
potentiometer
for
override settings while in the “Hand” position.
◆
◆
The
HPO-6701/6703/6705
boards are
designed to convert a binary/digital output
to a
relay
contact or
triac
output and to
provide “Hand-Off-Auto” control and feedback
functions.
