1. Introduction
The FX
2N
-5A analog special function block has four input channels and one output channel.
The input channels receive analog signals and converts them to the comparable digital values.
The output channel takes a digital value and outputs an equivalent analog signal.
1) Analog signal inputs can be selected from either voltage or current input. The applicable
analog signal input is set using the TO instruction supplied by the PLC main unit.
This PLC instruction is used to select different analog input signal types for each
corresponding channel.
2) The FX
2N
-5A can be connect to FX
2N
, FX
2NC
, FX
1N
or FX
0N
series of Programmable
Controllers (Hereafter referred to as a PLC).
3) Two FX
2N
-5A units can be connected to the one FX
0N
main unit, FX
0N
extension unit, FX
1N
Main unit.
Eight FX
2N
-5A units can be connected to one FX
2N
Series PLC. Four FX
2N
-5A Units can be
connected to one FX
2NC
Series PLC.
(For connection to the FX
2NC
Series PLC, an FX
2NC
-CNV-IF is required.)
Data transfer with the PLC is performed via buffer memories of the FX
2N
-5A using FROM/
TO Instructions.
