D20 EME 10BASE-T处理器控制模块,D20 EME 10BASE-T实验数据
90-30系列可编程逻辑控制器的120伏交流输入模块提供16个输入点，带有一个公共电源输入端子。输入电路是无功的（电阻器/电容器）输入。流入输入点的电流导致逻辑1处于输入状态表（%I）。输入特性与用户提供的各种输入兼容装置，如按钮、限位开关和电子接近开关。电源至操作现场设备必须由用户提供。此模块需要交流电源电源，不能与直流电源一起使用。
D20 EME 10BASE-T处理器控制模块提供每个点的开/关状态的LED指示灯位于单元该LED块有两个水平行，每行有八个绿色LED；顶部标记为A1到8（点1到8）的行和标记为B1到8（点）的底行9至16）。铰链门的内外表面之间有一个插件。这个朝向模块内部的表面（铰链门关闭时）具有电路布线信息和电路识别信息可以记录在外表面上。这个插件左边缘外侧的颜色编码为红色，表示高压模块。这模块可以安装在90-30系列PLC中5或10插槽基板的任何输入/输出插槽中系统下图提供了连接用户提供的输入设备的接线信息和120伏交流输入模块的电源。输入特性：接通状态电压74至132伏AC关闭状态电压0至20伏交流通态电流最小6 mA关断状态电流最大2.2 mA响应时间最长30毫秒关闭响应时间最长45毫秒背板上5伏总线的耗电90 mA（所有输入接通）
The 120 volt AC Input module for the Series 90-30 Programmable Logic Controller provides
16 input points with one common power input terminal. The input circuits are reactive
(resistor/capacitor) inputs. Current into an input point results in a logic 1 in the input status
table (%I). Input characteristics are compatible with a wide range of user-supplied input
devices, such as pushbuttons, limit switches, and electronic proximity switches. Power to
operate the field devices must be supplied by the user. This module requires an AC power
source, it cannot be used with a DC power source.
LED indicators which provide the ON/OFF status of each point are located at the top of the
module. This LED block has two horizontal rows with eight green LEDs in each row; the top
row labeled A1 through 8 (points 1 through 8) and the bottom row labeled B1 through 8 (points
9 through 16). An insert goes between the inside and outside surface of the hinged door. The
surface towards the inside of the module (when the hinged door is closed) has circuit wiring
information, and circuit identification information can be recorded on the outside surface. The
outside left edge of the insert is color-coded red to indicate a high-voltage module. This
module can be installed in any I/O slot of a 5 or 10-slot baseplate in a Series 90-30 PLC
system.The following figure provides wiring information for connecting user supplied input devices
and power source to the 120 volt AC input module.Input Characteristics:
On-state Voltage 74 to 132 volts AC
Off-state Voltage 0 to 20 volts AC
On-state Current 6 mA minimum
Off-state Current 2.2 mA maximum
On response Time 30 ms maximum
Off response Time 45 ms maximum
