FX3U-4AD module 4AI Mitsubishi
Description
FX3U-4AD Mitsubishi PLC Special Function Block Original Brand NEW
Introduction
The FX3U-4AD special function block for analog input converts four analog input values (voltage, current) to digital values and transfers those digital values to the PLC main unit.
Applicable PLC
Model name
Applicability
FX3U Series PLC
Ver. 2.20 or later (from first production)
Up to 8 blocks can be extended
FX3UC Series
PLC*1
Ver. 1.30 or later (from the production manufactured in August,
2004 with SER No. 48…………)
Up to 8 blocks can be extended*2
The version number can be checked by monitoring D8001 as the last three digits indicate it.
*1 An FX2NC-CNV-IF or FX3UC-1PS-5V is necessary to connect the FX3U-4AD with the FX3UC PLC.
*2 Up to 7 units can be connected to the FX3UC-32MT-LT(-2) PLC.

20mA
A/D conversion time
500µs × number of selected channels
(If channels use the digital filter(s): 5ms × number of selected
channels)
Insulation
method
The photo-coupler insulates the analog input area from the PLC.
The DC-DC converter insulates the analog input area from the power supply unit.
Channels are not insulated from each other.
*1 Change the offset and gain values to change the input characteristics. However, the resolution doesn’t change even when the offset and gain values change.
When the analog value direct indication is enabled in the input mode 2, 5, or 8, the offset value and the gain value don’t change.
*2 The offset and the gain should satisfy the following condition:1V <= (Gain - Offset)
*3 The offset and the gain should satisfy the following condition: 3 mA <=(Gain - Offset) <= 30 mA
*4 The input characteristics vary depending on the input mode to be used.
