DS215KLDBG1AZZ03A燃機(jī)卡件,DS215KLDBG1AZZ03A說明書
模塊的主要電源是由PLC提供的隔離+24 VDC電源電源。模塊的端子連接器上有兩個(gè)端子供用戶提供+24伏。這允許您提供備用電源,以便輸出可以繼續(xù)如果內(nèi)部電源丟失并且選擇了保持最后狀態(tài),則保持其值。此外,您還可以提供模塊電壓,以減少PLC隔離+24 VDC電源上的負(fù)載供給當(dāng)施加的電壓高于0.7伏時(shí),必須使用用戶電源隔離的+24 VDC電源,電壓范圍為21.5伏至26.5伏。頂部的LED當(dāng)模塊的電源工作時(shí),模塊的面板打開。
DS215KLDBG1AZZ03A燃機(jī)卡件為了最大限度地減少電容性負(fù)載和噪聲,所有現(xiàn)場(chǎng)連接應(yīng)使用良好的絞合屏蔽儀表電纜等級(jí)。屏蔽應(yīng)連接至接地用戶端子連接器塊。接地連接提供對(duì)基板的訪問(機(jī)架接地)可更好地抑制任何屏蔽漏電流引起的噪聲。

The primary power source for the module is the isolated +24 VDC power supplied by the PLC
power supply. Two terminals are provided on the module’s terminal connector for user supplied
+24 volts. This allows you to provide a standby power supply, so that the outputs can continue
to hold their value if the internal supply is lost and Hold Last State is selected. Additionally,
you can also supply the module voltage to reduce the load on the PLC isolated +24 VDC power
supply. The user supply must be used when the applied voltage is 0.7 volts higher than the
isolated +24 VDC supply, which can range from 21.5 volts to 26.5 volts. An LED at the top of
the module’s faceplate is ON when the module’s power supply is operating.
To minimize capacitive loading and noise, all field connections should be wired using a good
grade of twisted, shielded instrumentation cable. The shields should be connected to GND on
the user terminal connector block. The GND connection provides access to the baseplate
(frame ground) resulting in superior rejection of noise caused by any shield drain currents.
The module provides electrical isolation of externally generated noise between field wiring and
the backplane through the use of optical isolation. This module can be installed in any I/O slot
of a 5 or 10-slot baseplate in a Series 90-30 PLC system. Refer to page 3-11 to determine the
number of Analog Voltage Output modules that can be installed in a system.Voltage Range –10 to +10 volts
Calibration Factory calibrated to 2.5 mV per count
Supply Voltage (nominal) +24 VDC, from isolated +24 VDC on backplane or user supplied voltage source, and +5 VDC from backplane
External Supply Voltage Range 18 to 30 VDC
External Supply Voltage Ripple 10%
Update Rate 5 msec (both channels) This update rate is approximate since it is
determined by I/O scan time, and is application dependent.
Resolution 2.5 mV (1 LSB = 2.5 mV)
