90-30系列可編程邏輯控制器的120伏交流輸入模塊提供16個輸入點，帶有一個公共電源輸入端子。輸入電路是無功的（電阻器/電容器）輸入。流入輸入點的電流導致邏輯1處于輸入狀態(tài)表（%I）。輸入特性與用戶提供的各種輸入兼容裝置，如按鈕、限位開關和電子接近開關。電源至操作現(xiàn)場設備必須由用戶提供。此模塊需要交流電源電源，不能與直流電源一起使用。
D20 EME 10BASE-T處理器控制模塊提供每個點的開/關狀態(tài)的LED指示燈位于單元該LED塊有兩個水平行，每行有八個綠色LED；頂部標記為A1到8（點1到8）的行和標記為B1到8（點）的底行9至16）。鉸鏈門的內(nèi)外表面之間有一個插件。這個朝向模塊內(nèi)部的表面（鉸鏈門關閉時）具有電路布線信息和電路識別信息可以記錄在外表面上。這個插件左邊緣外側的顏色編碼為紅色，表示高壓模塊。這模塊可以安裝在90-30系列PLC中5或10插槽基板的任何輸入/輸出插槽中系統(tǒng)下圖提供了連接用戶提供的輸入設備的接線信息和120伏交流輸入模塊的電源。輸入特性：接通狀態(tài)電壓74至132伏AC關閉狀態(tài)電壓0至20伏交流通態(tài)電流最小6 mA關斷狀態(tài)電流最大2.2 mA響應時間最長30毫秒關閉響應時間最長45毫秒背板上5伏總線的耗電90 mA（所有輸入接通）
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
