1. Introduction
• The FX -3A analog special function block has two input channels and one output channel.
0N
The input channels receive analog signals and convert them into digital values.
The output channel takes a digital value and outputs an equivalent analog signal.
The FX -3A has a maximum resolution of 8 bits.
0N
• The selection of voltage or current based input/output is decided by user wiring.
• An FX -3A can connected to the FX
0N
(Hereafter referred to as a PLC).
• All data transfers and parameter setups are adjusted through software control for the FX
TO/FROM applied instructions in the PLC. Communications between the PLC and FX
protected by a photo-coupler.
• An FX -3A occupies 8 I/O points on the PLC's expansion bus. The 8 I/O points can be allocated from
0N
either inputs or outputs.

• When a current input is used, ensure that the terminals marked [VIN*1] and [IIN*1] are linked.
Do not connect the [VOUT] and [IOUT] terminals when the current output is used.
*1 terminal number 1 or 2 is identified here.
• If any voltage ripple is experienced on the voltage inputs/outputs or if there is excessive electrical
noise, connect a capacitor of 0.1 to 0.47μF,
