PXAH401操作面板,PXAH401使用在哪里
这种灵活性允许这些块与多种模拟输入和输出设备。区块的内部电源驱动电流模式输出负载,每个负载高达300欧姆。对于负载高达2K欧姆的外部24或48 VDC电源可以习惯于可配置块功能包括:每个输入和输出的独立缩放。
可以为每个服务器启用或禁用向主机的故障报告输入和输出。
可选输入滤波器时间高达1024ms。
每个输入可以在正常模拟输入模式下运行,或报告只有其报警状态。
PXAH401操作面板在任一正常输入中,每个输入的低报警限值和高报警限值模式或报警输入模式。
为每个输出通电默认值。
在以下情况下,可以将每个输出配置为保持上次状态或默认状态:CPU通信丢失。
输入低报警和高报警检测。
电流模式输入的开路检测。
输入欠量程或超量程。
输出欠量程或超量程。电压/电流4输入/2输出模拟块有四个独立的输入电路和两个独立的输出电路。二块版本可用:115 VAC电压/电流模拟输入/输出块(IC66*BBA100)
24/48 VDC电压/电流模拟输入/输出块(IC66*BBA020)
除了电源外,这些模块是相同的
This flexibility allows these blocks to be used with a wide variety of
analog input and output devices. The block’s internal power supply
drives current mode output loads up to 300 Ohms each. For loads
up to 2K Ohms, an external 24 or 48 VDC power supply can be
used.
Configurable block features include:
Independent scaling for each input and output.
Fault reports to the host can be enabled or disabled for each
input and output.
Selectable Input Filter Time up to 1024ms.
Each input can operate in normal analog input mode, or report
only its alarm status.
Low and high alarm limits for each input, in either normal input
mode or alarm input mode.
Powerup default values for each output.
Each output can be configured to hold last state or default if
CPU communications are lost.
Input Low Alarm and High Alarm detection.
Open Wire detection on current mode inputs.
Input Underrange or Overrange.
Output Underrange or Overrange.Voltage/Current 4 Input/2 Output Analog Blocks have four
independent input circuits and two independent output circuits. Two
block versions are available:
115 VAC Voltage/Current Analog I/O Block (IC66*BBA100)
24/48 VDC Voltage/Current Analog I/O Block
(IC66*BBA020)
These blocks are identical except for the power supply
