Conformance to EC Directives
• EMC Directive
 EMC Directive
The Digital Sensor Communications Unit is an electrical device that is built into other machines. To
enable more easily building it into other machines, it has been checked for conformity to EMC
standards.*
EMC-related performance of the Unit will vary depending on the configuration, wiring, and other
conditions of the equipment or control panel on which it is installed.
The customer must, therefore, perform the final check to confirm that devices and the overall
machine conform to EMC standards.
* Note: Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN 61326-1
EMI (Electromagnetic Interference): EN 61326-1
The Digital Sensor Communications Unit complies with EC Directives. To ensure that the machine in
which the Unit is used complies with EC Directives, the Unit must be installed as follows:
• The Unit must be installed within a control panel.
• You must use reinforced insulation or double insulation for the DC power supplies for
communications, internal power, and I/O. The DC power supplies must provide stable power even
when a momentary power interruption of 10 ms occurs in the input.
We recommend using an OMRON S8JX-series Power Supply.*
• Products complying with EC Directives also conform to the Emission Standards (EN 61326-1).
Radiated emission characteristics (10-m regulations) may vary depending on the configuration of the
control panel used, other devices connected to the control panel, wiring, and other conditions. You must
therefore confirm that the overall machine or equipment complies with EC Directives.
• Compliance was confirmed for I/O wiring of less than 30 m.
* Conformance with the EMC Directive was confirmed when using the recommended power supply.
