Analog Output (AO) modules receive
output signals from the Main Processor
module on each of three channels. Each
set of data is then voted and a healthy
channel is selected to drive the outputs.
Each module monitors its own current
outputs (as input voltages) and main
tains an internal voltage reference to
provide self-calibration and module
health information.
Each channel on a module has a current
loopback circuit which verifies the
accuracy and presence of analog
signals independently of load presence
or channel selection. The module’s
design prevents a non-selected channel
from driving an analog signal to the
field. In addition, ongoing diagnostics
are performed on each channel and
circuit of the module. Failure of any
diagnostic test deactivates the faulty
channel and activates the Fault indi
cator and the chassis alarm. The
module Fault indicator merely indicates
a channel fault, not a module failure.
The module continues to operate prop
erly with as many as two channels
failed. Open loop detection is provided
by a LOAD indicator which activates if
the module is unable to drive current to
one or more outputs.
The module provides for redundant
loop power sources with individual
power and fuse indicators called PWR1
and PWR2. External loop power
supplies for analog outputs must be
provided by the user. A LOAD indi
cator activates if an open loop is
detected on one or more output points.
PWR1 and PWR2 are on if loop power
is present.
AO modules support hot- spare capa
bility, which allows online replacement
of a faulty module.
AO modules require a separate external
termination panel (ETP) with a cable
interface to the Tricon backplane. Each
module is mechanically keyed to
prevent improper installation in a
configured chassis.
The Model 3805H module has been
modified to support increased inductive
