PDP800處理器模塊,PDP800中文說明
PACSystems*8通道模擬電流/電壓輸出模塊，ALG392，提供多達八個單端輸出通道和電流回路輸出和/或電壓輸出。每個輸出通道都可以使用以下任何范圍的配置軟件：? 0至+10伏（單極）? -10至+10伏（雙極）? 0至20毫安? 4至20毫安每個通道能夠轉(zhuǎn)換15到16位（取決于范圍選擇）將二進制數(shù)據(jù)傳輸?shù)侥M輸出。所有八個通道都已更新每8毫秒。在當前模式下，模塊向CPU報告每個頻道當系統(tǒng)通電時，模塊可能會進入已知的最后狀態(tài)打斷。
PDP800處理器模塊只要向模塊施加外部電源，每個輸出將按配置保持其最后值或重置為零。該模塊可以安裝在RX3i或90-30系列系統(tǒng)的任何輸入/輸出插槽中。隔離+24 VDC電源模塊必須從外部電源接收其24 VDC電源，該電源必須直接連接到模塊的接線板。在存在嚴重射頻干擾的情況下，精度可能會降低到?電流的1%滿標度（FS）輸出和?電壓輸出為3%FS。有關(guān)產(chǎn)品標準和概述，請參閱PACSystems RX3i系統(tǒng)手冊GFK-2314規(guī)范。為了滿足PAC系統(tǒng)附錄A中規(guī)定的射頻敏感性水平
RX3i系統(tǒng)手冊，當存在此模塊時，系統(tǒng)必須安裝在金屬外殼中。
The PACSystems* 8-Channel Analog Current/Voltage Output module,
ALG392, provides up to eight single-ended output channels with current loop
outputs and/or voltage outputs. Each output channel can be set up using the
configuration software for any of these ranges:
? 0 to +10 volts (unipolar)
? -10 to +10 volts (bipolar)
? 0 to 20 milliamps
? 4 to 20 milliamps
Each channel is capable of converting 15 to 16 bits (depending on the range
selected) of binary data to an analog output. All eight channels are updated
every 8 milliseconds.
In current modes, the module reports an Open Wire fault to the CPU for each
channel. The module can go to a known last state when system power is
interrupted. As long as external power is applied to the module, each output
will maintain its last value or reset to zero, as configured.
This module can be installed in any I/O slot of an RX3i or Series 90-30 system.
Isolated +24 VDC Power
The module must receive its 24 VDC power from an external source, which
must be connected directly to the module’s terminal block.In the presence of severe RF interference, accuracy may be degraded to ?1% full scale (FS) for current
outputs and ?3% FS for voltage outputs.
Refer to the PACSystems RX3i Systems Manual, GFK-2314, for product standards and general
specifications. In order to meet the levels for RF Susceptibility specified in Appendix A of the PACSystems
