PXAH401操作面板,PXAH401使用在哪里
這種靈活性允許這些塊與多種模擬輸入和輸出設(shè)備。區(qū)塊的內(nèi)部電源驅(qū)動電流模式輸出負(fù)載，每個(gè)負(fù)載高達(dá)300歐姆。對于負(fù)載高達(dá)2K歐姆的外部24或48 VDC電源可以習(xí)慣于可配置塊功能包括：每個(gè)輸入和輸出的獨(dú)立縮放。
可以為每個(gè)服務(wù)器啟用或禁用向主機(jī)的故障報(bào)告輸入和輸出。
可選輸入濾波器時(shí)間高達(dá)1024ms。
每個(gè)輸入可以在正常模擬輸入模式下運(yùn)行，或報(bào)告只有其報(bào)警狀態(tài)。
PXAH401操作面板在任一正常輸入中，每個(gè)輸入的低報(bào)警限值和高報(bào)警限值模式或報(bào)警輸入模式。
為每個(gè)輸出通電默認(rèn)值。
在以下情況下，可以將每個(gè)輸出配置為保持上次狀態(tài)或默認(rèn)狀態(tài)：CPU通信丟失。
輸入低報(bào)警和高報(bào)警檢測。
電流模式輸入的開路檢測。
輸入欠量程或超量程。
輸出欠量程或超量程。電壓/電流4輸入/2輸出模擬塊有四個(gè)獨(dú)立的輸入電路和兩個(gè)獨(dú)立的輸出電路。二塊版本可用：115 VAC電壓/電流模擬輸入/輸出塊（IC66*BBA100）
24/48 VDC電壓/電流模擬輸入/輸出塊（IC66*BBA020）
除了電源外，這些模塊是相同的
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
