當模塊的電源工作時，面板頂部的LED亮起。主要
模塊的電源為PLC電源提供的隔離+24 VDC電源。
該電壓通過逆變器/調節器傳輸，為模塊提供工作電壓。
該模塊還消耗來自PLC電源的+5 VDC輸出的電源，以驅動
隔離電路。該模塊可以安裝在5或10插槽基板的任何I/O插槽中

Input protection for the module is sufficient to guarantee operation with reduced performance
with up to 200V common-mode. The module provides electrical isolation of externally
generated noise between field wiring and the backplane through the use of optical isolation.
To minimize the capacitive loading and noise, all field connections to the module should be
wired using a good grade of twisted, shielded instrumentation cable. The shields can be
connected to either COM or GND. The COM connection provides access to the common of the
analog circuitry in the module. The GND connection provides access to the baseplate (frame
ground).
An LED at the top of the faceplate is ON when the module’s power supply is operating. The main
power source for the module is the isolated +24 VDC power supplied by the PLC power supply.
This voltage is routed through an inverter/regulator to provide the operating voltage for the module.
This module also consumes power from the +5 VDC output of the PLC power supply to drive the
isolation circuitry. This module can be installed in any I/O slot of a 5 or 10-slot baseplate in a
Series 90-30 PLC system. See page 3-11 to determine the number of Analog Current Input
modules that can be installed in a system.
