FX2N-5A Special function block 1. Introduction 1 Introduction The FX2N-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.
