3BSE081230R1处理器模块
架子每个机架组件包含一个子机架、工程卡、直流输入卡、钥匙套件以及必要时的互连电缆。根据配置，控制系统安装在四个标准尺寸的子架如下：a、 全19英寸宽乘3U高-零件号05701-a-0511，用于后部现场接线连接。b、 全19英寸宽乘6U高-零件号05701-A-0501，用于前部现场接线连接。c、 半个19英寸宽乘3U高-零件号05701-A-0512，用于后部现场接线连接。d、 半个19英寸宽乘6U高-零件号05701-A-0502，用于前部现场接线连接。所有四个版本都有两个单独的腔室。一个是密封的电磁干扰和包含控制卡，而其他腔室包含现场/继电器接口卡。背板两个腔室之间提供了一条信号路由路径单个卡和工程卡以及电源配电柜
两个壁挂式机柜用于容纳：
a、 全宽16通道前访问机架，（零件号05701-A-0451）
b、 或八通道半宽前访问机架。（零件号05701-A-0452）
每个机柜上的前门提供安全和防尘保护，门上的透明面板允许通道卡显示：门关闭时查看。每个机柜的底座包含一个预成型分型电缆压盖入口的选择。
5701单通道控制卡提供：a的控制、显示和报警设施连接气体检测器。前面板显示器指示气体读数和通道状态而LED用于报警。按钮用于重置报警和选择与工程卡一起使用的卡。
控制卡的操作是：微处理器控制，完全可定义适用于各种连接的气体探测器以及应用要求。软件配置设置存储在EEPROM中。
有两种类型的控制卡，具体取决于：安装在系统：
a、 单通道控制卡4-20mA。零件号05701-A-0301。
b、 单通道控制卡催化。零件号05701-A-0302。
上述每个控制卡由一单通道控制卡，配备相应的插入式传感器驱动模块。
可选的模拟输出模块也可以：
插入单通道控制卡提供通道卡的远程输出读数。
RACKS
Each rack assembly contains a sub-rack, Engineering Card, DC Input
Card, key kit and where necessary an interconnecting cable.
Dependent upon configuration, the control system is housed in one of
four standard size sub-racks as follows:
a. Full 19 inch wide by 3U high - Part Number 05701-A-0511,
for rear field wiring connections.
b. Full 19 inch wide by 6U high - Part Number 05701-A-0501,
for front field wiring connections.
c. Half 19 inch wide by 3U high - Part Number 05701-A-0512,
for rear field wiring connections.
d. Half 19 inch wide by 6U high - Part Number 05701-A-0502,
for front field wiring connections.
All four versions have two separate chambers. One is sealed against
electromagnetic interference and contains the control cards while the
other chamber contains the field/relay interface cards. A backplane
between the two chambers provides a path for signal routeing between
individual cards and the Engineering Card, and power supply
distribution.CABINETS
Two wall mounted cabinets are used to house:
a. the full width 16 channel front access rack,
(Part Number 05701-A-0451)
b. or the eight channel half width front access rack.
(Part Number 05701-A-0452)
A front door on each cabinet provides security and dust protection,
while a clear panel in the door allows the channel card displays to be
viewed when the door is closed. The base of each cabinet contains a
selection of preformed knockout cable gland entries.
The 5701 Single Channel Control Card provides
control, display and alarm facilities for a
connected gas detector. The front panel display
indicates the gas reading and channel status
while LEDs are used for alarms. A push-button
is provided for resetting the alarms and selecting
the card for use with the Engineering Card.
The operation of the control card is
microprocessor controlled and is fully definable
for a wide range of connected gas detectors
and application requirements. The software
configuration setup is stored in an EEPROM.
There are two types of control card depending
on the type of gas detector being fitted to the
system:
a. Single Channel Control Card 4 - 20mA.
Part Number 05701-A-0301.
b. Single Channel Control Card Catalytic.
Part Number 05701-A-0302.
Each of the above control cards consist of a
single channel control card fitted with the
respective plug-in sensor drive module.
An optional Analogue Output Module can also
be plugged into the single channel control card
to provide a remote output of the channel card
readings.
