Compliance with EC directive (CE Marking)
This note does not guarantee that an entire mechanical module produced in accordance with the contents
of this note will comply with the following standards.
Compliance to EMC directive and LVD directive for the entire mechanical module should be checked by
the user/manufacturer. For more information please consult with your nearest Mitsubishi product provider.
Regarding the standards that comply with the main unit, please refer to either the FX series product
catalog or consult with your nearest Mitsubishi product provider.
Requirement for Compliance with EMC directive
The following products have shown compliance through direct testing (of the identified standards below)
and design analysis (through the creation of a technical construction file) to the European Directive for
Electromagnetic Compatibility (2014/30/EU) when used as directed by the appropriate documentation.
Attention
This product is designed for use in industrial applications.

Caution for EC Directive
The FX
-2AD have been found to be compliant to the European standards in the aforesaid manual and
2N
directive. However, for the very best performance from what are in fact delicate measuring and controlled
output device Mitsubishi Electric would like to make the following points;
As analog devices are sensitive by nature, their use should be considered carefully.
For users of proprietary cables (integral with sensors or actuators), these users should follow those
manufacturers installation requirements.
Mitsubishi Electric recommend that shielded cables should be used. If NO other EMC protection is provided,
then users may experience temporary loss or accuracy between ±10% in very heavy industrial areas.
However, Mitsubishi Electric suggest that if adequate EMC precautions are followed for the users
complete control system, users should expect accuracy as specified in this manual.
Sensitive analog cable should not be laid in the same trunking or cable conduit as high voltage
cabling. Where possible users should run analog cables separately.
Good cable shielding should be used. When terminating the shield at Earth - ensure that no earth
loops are accidentally created.
When reading analog values, EMC accuracy can be improved out by averaging the readings. This
can be achieved either through functions on the through a users program in the main unit.

Summary of Contents for Mitsubishi Electric FX2N-2AD

  • Page 1 For users of proprietary cables (integral with sensors or actuators), these users should follow those manufacturers installation requirements. Mitsubishi Electric recommend that shielded cables should be used. If NO other EMC protection is provided, then users may experience temporary loss or accuracy between ±10% in very heavy industrial areas.
  • Page 2 1. Introduction The FX -2AD type analog input block (hereafter referred to as the FX -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).
