FX2N-5A Special function block

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. This PLC instruction is used to select different analog input signal types for each corresponding channel.

5.1 Caution

1) Do not lay signal cabling near to high voltage power cabling or house them in the same

trunking duct. Effects of noise or surge induction may occur. Keep signal cables at safe distance of more than 100 mm (3.94") from these power cables.

Wiring 5

2) The terminal screws of the FX

-5A are M3 (0.12"), therefore crimp style terminals (see

drawing) suitable for use with these screws should be fitted to the cable for wiring.

4) Cut off all phases of power source before installation or performing wiring work in order to avoid electric shock or product damage.

5) Remount the provided terminal cover before supplying power and operating the unit after installation or wiring work in order to avoid electric shock.
