System Configuration; Applicable Plc - Mitsubishi FX1N-2AD-BD User Manual

1. Introduction
The FX -2AD-BD analog input expansion board (hereafter called "2AD" or "expansion board") is to be
1N
installed in an FX
1S
1.1 Features of 2AD
1) Analog input of two points can be increased using 2AD. If a 2AD is used, internal mounting in the top
of the PLC means that there is no need for a change to the installation area of the PLC.
2) Voltage input (0 ~10V) or current input (4 ~ 20mA) for analog to digital conversion can be set by
switching the auxiliary relays assigned to each channel.
Moreover, a digital value after conversion of each channel is stored in special data register allocated
to each channel, as shown in the table below.
However, the analog to digital conversion characteristic cannot be adjusted.
