PDP800处理器模块,PDP800中文说明
PACSystems*8通道模拟电流/电压输出模块，ALG392，提供多达八个单端输出通道和电流回路输出和/或电压输出。每个输出通道都可以使用以下任何范围的配置软件：▪ 0至+10伏（单极）▪ -10至+10伏（双极）▪ 0至20毫安▪ 4至20毫安每个通道能够转换15到16位（取决于范围选择）将二进制数据传输到模拟输出。所有八个通道都已更新每8毫秒。在当前模式下，模块向CPU报告每个频道当系统通电时，模块可能会进入已知的最后状态打断。
PDP800处理器模块只要向模块施加外部电源，每个输出将按配置保持其最后值或重置为零。该模块可以安装在RX3i或90-30系列系统的任何输入/输出插槽中。隔离+24 VDC电源模块必须从外部电源接收其24 VDC电源，该电源必须直接连接到模块的接线板。在存在严重射频干扰的情况下，精度可能会降低到电流的1%满标度（FS）输出和电压输出为3%FS。有关产品标准和概述，请参阅PACSystems RX3i系统手册GFK-2314规范。为了满足PAC系统附录A中规定的射频敏感性水平
RX3i系统手册，当存在此模块时，系统必须安装在金属外壳中。
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
