FX2N-2AD SPECIAL FUNCTIONBLOCK USER’S GUIDE JY992D74701D This manual contains text, diagrams and explanations which will guide the reader in the correct installation and operation of the FX2N-2AD special function block and should be read and understood before attempting to install or use the unit. Further information can be found in the FX SERIES PROGRAMMING MANUAL(ΙΙ), FX0N/FX1N/FX2N/ FX2NC SERIES HARDWARE MANUAL of each PLC. 1. Introduction The FX2N-2AD type analog input block (hereafter referred to as the FX2N-2AD) is used to convert the analog input of two points (voltage and current input) into a digital value of 12 bits, and to forward the values to the Programmable Controller (hereafter referred to as a PLC). FX2N-2AD can connected to the FX0N, FX1N, FX2N, and the FX2NC series Programmable Controllers. 1) The analog input is selected from the voltage or current input by the method of connecting wires. At this time, assume the setting to be two channels common analog input (voltage or current input). 2) The analog to digital conversion characteristics can be adjusted. 3) The block occupies 8 I/O points which can be allocated from either inputs or outputs. 4) The data transfer with the PLC uses the FROM/TO instructions. 2. External Dimensions and Parts Dimensions: mm (inches) 3. Wiring *1 The FX2N-2AD cannot have 1 channel as an analog voltage input and one channel as current input because both channels use the same offset and gain values. For current input please short circuit VIN and IIN as shown in the diagram. *2 Connect a 0.1 to 0.47 µF 25V DC capacitor with the position of *2 when there is voltage ripple in the voltage input or there will be a lot of noise. ����� �� � ��� ����� ���� � � � � � � � � � � � � � � � � � � � � � � ������ �� ���� �������� ��� �������� !��" � !��" #$% &'$�() *�� �+&'$��) �"������ ,�"- �.�"� ��� ,�/�" #+&�$01) ( ' & + $ � % ) (2&+$#+) 1&'$+%) #&'$�0) 1 ' & + $ % # ) +%��&�$+() � � � � � � � � � � � � � � � � � � � � � � � � ���� ������ �3 ������ 4����" �3 ���� 4����" Mass (Weight):0.2kg (0.44lbs) Accessories: Special Function block number label *2 VIN{ IIN{ COM{ *1 VIN{ IIN{ COM{ 37.3KΩ 250Ω 165KΩ 165KΩ 37.3KΩ 250Ω PLC Extension cable FX2N-2AD AG Voltage input 0~10V DC Current input 4~20mA Channel number enter { 4.
