DS215KLDBG1AZZ03A燃机卡件,DS215KLDBG1AZZ03A说明书
模块的主要电源是由PLC提供的隔离+24 VDC电源电源。模块的端子连接器上有两个端子供用户提供+24伏。这允许您提供备用电源，以便输出可以继续如果内部电源丢失并且选择了保持最后状态，则保持其值。此外，您还可以提供模块电压，以减少PLC隔离+24 VDC电源上的负载供给当施加的电压高于0.7伏时，必须使用用户电源隔离的+24 VDC电源，电压范围为21.5伏至26.5伏。顶部的LED当模块的电源工作时，模块的面板打开。
DS215KLDBG1AZZ03A燃机卡件为了最大限度地减少电容性负载和噪声，所有现场连接应使用良好的绞合屏蔽仪表电缆等级。屏蔽应连接至接地用户端子连接器块。接地连接提供对基板的访问（机架接地）可更好地抑制任何屏蔽漏电流引起的噪声。
该模块在现场接线和背板通过使用光学隔离。该模块可以安装在任何输入/输出插槽中90-30系列PLC系统中的5或10槽基板。参考第3-11页确定可安装在系统中的模拟电压输出模块的数量。电压范围–10至+10伏校准工厂校准至每次计数2.5 mV电源电压（标称）+24 VDC，来自背板上的隔离+24 VDC或用户提供的电压源，以及来自背板的+5 VDC外部电源电压范围18至30 VDC外部电源电压纹波10%更新率5毫秒（两个通道）此更新率是近似值，因为它是由输入/输出扫描时间决定，并取决于应用程序。分辨率2.5 mV（1 LSB=2.5 mV）25°C（77°F）时的绝对精度±5 mV
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)
