HOA-5
and
HOA-9
are 4 and 8 channel Universal Output Override
Modules. They allow for up to 4 or 8 digital (relay) outputs and one
analog output(0-10VDC) to be controlled manually(on or off , by the
user) or automatically(by the Controller). The selection, made via a 3
position dual pole toggle switch, will allow the digital or analog output
to be set one of three states, " AUTO - OFF - ON(Hand)". Both
Modules have a voltage output feedback for The Controller to detect the
number of active HOA switches.
FEATURES:
•
Hand, Off, Auto Module allows for loads to be controlled either
manually or by the IZAC Controller.
•
The 0-10VDC Analog Channel's three position toggle switch can
be set to: Automatic(Controller operated), 0 volts (open), or any
desirable 0-10VDC adjustable voltage output. An on-board 0-
10VDC adjustable analog output source allows for manual
selection of a 0-10VDC signal, via a built-in adjust potentiometer,
on the analog override output.
•
Using Transient Absorbers (transorbs) located between each output
and ground terminal, each output is designed to protect Controller
from high voltage(40VAC) transients and voltage spikes that can
propagate through load connections. HOA Modules are designed to
protect Controllers from surges or back voltages propagating
through inductive load connections.
•
Each output is fuse protected from over-current via solid state reset-
able 3 Amps fuses.
•
Power to the module and each output channel has a high intensity
Light Emitting Diode(LED) status indicator. The output LEDs are
ON when the output is energized Automatically or if they are
manually overridden ON.
•
While HOA-4, HOA-8 Modules are designed to fit nicely together
with IZAC-4 and IZAC-8 Controllers, these modules are not
restricted to these controllers and can be used with other controllers
that require these override features.
•
The overridden channels generate unique voltage output that can be
read by the Analog Input of the Controller to detect the number of
active override channels.
•
Can control 4 or 8 channels of Digital ( Relay ) Outputs and one 0-
to-10 VDC Analog Output for a total of 5 or 9 channels of override
capability.
•
Removable terminal blocks and modular design allows for easy
installation and operation.
APPLICATIONS:
•
Manual control of loads for service operations.
•
Manual 0-10VDC output adjustment can be used to test or adjust 0-
10VDC devices.
•
Switch voltage feedback can allow for the Controller to detect
when the unit is in service or perform other program related
operations.
•
Internal electrical protection makes the device useful in suppressing
harmful voltages in electrically noisy environments.
