热电偶输入模块
包括三个独立的输入通道。每个输入通道接收来自每个点的可变电压信号，
执行热电偶线性化和冷端补偿，以及将结果转换为摄氏度或
华氏的然后，每个通道传输16位有符号整数，表示0.125度/计数到3
按需提供主处理器。在TMR中模式，然后使用中值选择算法确保为每次扫描更正数据。
每个热电偶输入模块可编程以支持一种热电偶类型，从J、K和T中选择
97590-8 BD-PCI4PORT卡件用于标准热电偶输入模块和来自J、K、T和E的通道激活故障指示灯，
从而激活机箱报警信号。模块故障指示器仅报告通道故障，而不是
模块故障。模块继续使用最多两个故障通道。
热电偶输入模块支持热备盘功能，允许在线更换故障模块。
热电偶输入模块需要单独的外部接线板
（ETP）与Tricon背板。每个模块通过机械键连接到
防止在已配置机箱。隔离热电偶输入模块。
97590-8 BD-PCI4PORT卡件隔离模块允许用户选择高标度或低标度燃尽
TriStation 1131检测。对于非隔离模块，高档或
范围燃尽检测取决在选定的字段终止上。
三重温度传感器位于现场终端面板上支持冷端补偿。
热电偶输入的每个通道模块执行自动校准
使用内部精密电压参考。在隔离模块上故障冷端传感器为
由前面板上的冷接点指示器发出警报。
每个模块完成每个通道上的持续诊断。
Thermocouple Input Modules
Thermocouple Input (TC) modules
include three independent input chan
nels. Each input channel receives vari
able voltage signals from each point,
performs thermocouple linearization
and cold-junction compensation, and
converts the result to degrees Celsius or
Fahrenheit. Each channel then trans
mits 16-bit signed integers representing
0.125 degrees per count to the three
Main Processors on demand. In TMR
mode, a value is then selected using a
mid-value selection algorithm to ensure
correct data for every scan.
Each Thermocouple Input Module is
programmable to support one thermo
couple type, selected from J, K and T
for standard Thermocouple Input
Modules and from J, K, T and E for
channel activates the Fault indicator,
which in turn activates the chassis
alarm signal. The module Fault indi
cator merely reports a channel fault, not
a module failure. The module continues
to operate properly with as many as two
faulty channels.
Thermocouple Input Modules support
hot-spare capability, which allows
online replacement of a faulty module.
Thermocouple Input 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.
isolated Thermocouple Input Modules.
The isolated module allows users to
select upscale or downscale burnout
detection with TriStation 1131. For
non-isolated modules, upscale or
downscale burnout detection depends
on the field termination selected.
Triplicated temperature transducers
residing on the field termination panel
support cold-junction compensation.
Each channel of a Thermocouple Input
Module performs auto-calibration
using internal precision voltage refer
ences. On the isolated module, a
faulting cold-junction transducer is
annunciated by a cold-junction indi
cator on the front panel.
Each module performs complete
ongoing diagnostics on each channel.
