A
EMC Directive related standards
■ Emission requirements
Standard: EN61131-2:2007
*1 QP: Quasi-Peak value, Mean: Average value
*2 Programmable controller is an open-type device and must be placed in a conductive control panel or similar type of enclosure. The tests
were conducted with the programmable controller installed in a control panel, applying the maximum rated input voltage of the power
supply module.
■ Immunity requirements
Standard: EN61131-2:2007
*1 Programmable controller is an open-type device and must be placed in a conductive control panel or similar type of enclosure. The tests
were conducted with the programmable controller installed in a control panel.
*2 The accuracy of an analog-digital converter module may temporarily vary within 10%.
