SPASI23模塊卡件,SPASI23參數(shù)說明
模擬電流/電壓輸入/輸出模塊ALG442提供四個差分輸入通道和兩個單端輸出通道。每個通道可以使用機器版軟件配置為以下范圍：? 默認值為0至+10伏（單極）。? -10至+10伏（雙極）? 0至20 mA? 4至20 mA輸入通道也可以配置為4-20 mA增強模式。該模塊可以安裝在任何具有串行連接器的輸入/輸出插槽中RX3i或90-30系列系統(tǒng)。
SPASI23模塊卡件模塊功能輸出可以配置為保持最后狀態(tài)或重置為低如果系統(tǒng)電源中斷，則其范圍結(jié)束。輸出也可以是配置為在應(yīng)用程序發(fā)出命令時以斜坡模式運行程序在斜坡模式下，輸出通道轉(zhuǎn)換為一個新值一段時間，而不是立即獲取新值。可以為所有輸入通道和開路設(shè)置高報警限值和低報警限值每個輸出都可以向CPU報告故障（電流輸出模式頻道RX3i機架中的ALG442模塊支持現(xiàn)場固件升級。隔離+24 VDC電源該模塊需要150 mA外加來自用戶提供的+24的回路電流VDC電源LED模塊OK LED提供以下模塊狀態(tài)信息：開啟：狀態(tài)正常，模塊已配置；關(guān)閉：無背板電源或軟件未運行（看門狗計時器超時）；連續(xù)快速閃爍：未從CPU接收到配置數(shù)據(jù)；緩慢閃爍，然后關(guān)閉：通電診斷失敗或遇到代碼執(zhí)行錯誤。用戶電源LED指示外部24 VDC電源在規(guī)格范圍內(nèi)。
Analog Current/Voltage Input/Output module, ALG442, provides four
differential input channels and two single-ended output channels. Each
channel can be configured with the Machine Edition software for one of the
following ranges:
? 0 to +10 volts (unipolar), default.
? -10 to +10 volts (bipolar)
? 0 to 20 mA
? 4 to 20 mA
Input channels can also be configured for 4 - 20 mA Enhanced mode.
This module may be installed in any I/O slot that has a serial connector in an
RX3i or Series 90-30 system.
Module Features
Outputs can be configured to either Hold Last State or to reset to the low
end of their range if system power is interrupted. Outputs can also be
configured to operate in ramp mode on command from the application
program. In ramp mode, the output channel transitions to a new value over
a period of time, rather than taking the new value immediately.
High and low alarm limits can be set for all input channels and an open-wire
fault (current output modes) can be reported to the CPU for each output
channel.
ALG442 modules in RX3i racks support firmware upgrades in the field.
Isolated +24 VDC Power
This module requires 150 mA plus loop current(s) from a user-supplied +24
VDC supplyLEDs
The MODULE OK LED provides module status information as follows:
ON: status is OK, module configured;
OFF: no backplane power or software not running (watchdog timer timed out);
Continuous rapid blinking: configuration data not received from CPU;
Slow blinking, then OFF: failed power-up diagnostics or encountered code execution error.
