每個(gè)機(jī)柜上的前門提供安全和防塵保護(hù)，門上的透明面板允許通道卡顯示：門關(guān)閉時(shí)查看。每個(gè)機(jī)柜的底座包含一個(gè)預(yù)成型分型電纜壓蓋入口的選擇。
5701單通道控制卡提供：a的控制、顯示和報(bào)警設(shè)施連接氣體檢測器。前面板顯示器指示氣體讀數(shù)和通道狀態(tài)而LED用于報(bào)警。按鈕用于重置報(bào)警和選擇與工程卡一起使用的卡。
控制卡的操作是：微處理器控制，完全可定義適用于各種連接的氣體探測器以及應(yīng)用要求。軟件配置設(shè)置存儲(chǔ)在EEPROM中。
有兩種類型的控制卡，具體取決于：安裝在系統(tǒng)：
a、 單通道控制卡4-20mA。零件號(hào)05701-A-0301。
b、 單通道控制卡催化。零件號(hào)05701-A-0302。
上述每個(gè)控制卡由一單通道控制卡，配備相應(yīng)的插入式傳感器驅(qū)動(dòng)模塊。
可選的模擬輸出模塊也可以：
插入單通道控制卡提供通道卡的遠(yuǎn)程輸出讀數(shù)。
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.
