模拟输出（AO）模块接收
来自主处理器的输出信号
三个通道中的每个通道上的模块。每个对一组数据进行投票，并得到一个健康的选择通道来驱动输出。
每个模块监控自己的电流输出（作为输入电压）和main tain a internal voltage reference to
提供自校准和模块健康信息。
模块上的每个通道都有一个电流用于验证模拟的准确性和存在性
独立于负载存在的信号或频道选择。模块的设计可防止未选择的通道
从驱动模拟信号到领域此外，正在进行的诊断
GJR2395400R1210卡件在每个通道上执行，并且模块电路。任何故障诊断测试停用故障
引导并激活故障指示器和机箱警报。这个模块故障指示灯仅指示通道故障，而非模块故障。
模块继续使用多达两个通道运行失败。提供开环检测通过负载指示器，如果
模块无法将电流驱动到一个或多个输出。
该模块提供了冗余功能回路电源与单独

模拟输出电源必须由用户提供。如果开环
在一个或多个输出点上检测到。如果回路电源接通，PWR1和PWR2接通存在。
GJR2395400R1210卡件AO模块支持热备盘能力，允许在线更换出现故障的模块。
AO模块需要单独的外部带电缆的终端面板（ETP）
Tricon背板接口。每个模块通过机械键连接到防止在已配置机箱。
3805H型模块经过修改以支持增加的感应
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
