Flowserve F5-MEC模塊,F5-MEC數據庫
用于90-30系列可編程邏輯的24伏交流/直流正極/負極輸入模塊控制器在一組中提供16個輸入點，帶有公共電源輸入端子。這輸入模塊設計為在直流中具有正或負邏輯特性輸入模式。該輸入模塊設計用于交流或直流用戶輸入。輸入特性與廣泛的用戶提供的輸入設備兼容，例如按鈕、限位開關和電子接近開關。輸入點電流在輸入狀態表（%I）中產生邏輯1。操作現場設備的功率可以是由用戶提供，或電源上的隔離+24 VDC輸出（底部兩個電源電源端子）可用于為有限數量的直流輸入供電。
Flowserve F5-MEC模塊提供每個點的開/關狀態的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）。鉸鏈門的內外表面之間有一個插件。這個朝向模塊內部的表面（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用藍色編碼，表示低壓模塊。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/輸出插槽中系統下圖提供了連接用戶提供的輸入設備的接線信息和24伏交流/直流正極/負極邏輯輸入模塊的電源。

The 24 volt AC/DC Positive/Negative Input module for the Series 90-30 Programmable Logic
Controller provides 16 input points in one group with a common power input terminal. This
input module is designed to have either positive or negative logic characteristics in the DC
input mode. This input module is designed to function with AC or DC user inputs. Input
characteristics are compatible with a wide range of user-supplied input devices, such as
pushbuttons, limit switches, and electronic proximity switches. Current into an input point
results in a logic 1 in the input status table (%I). Power to operate the field devices can be
supplied by the user, or the Isolated +24 VDC output on the power supply (bottom two power
supply terminals) can be used to power a limited number of DC inputs.
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 blue to indicate a low-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 24 volt AC/DC positive/negative logic input module.
