1. Introduction
The FX1N-4EX-BD Input Expansion Board (hereafter referred to as "FX1N-4EX-BD" or "Function
expansion board") is a function expansion board to be installed in the FX
1S
or FX1N series programmable
controller (hereafter referred to as "PLC"), to increase the input of four points.
1.1 Features of the FX1N-4EX-BD
1) Additional increase of four input points.
2) Internal mounting in the top of the PLC meaning no need for change to the installation area of the
PLC.
3) Additional inputs have special auxiliary relays allocated to each point, which are turned ON and OFF
depending on the input state of the FX
1N
-4EX-BD.
As special auxiliary relays are used in the PLC program for the input points, the additional inputs are
not included in the regular system I/O count.
