Appendix 6 EMC and Low Voltage Directives
Requirements to compliance with the Low Voltage Directive
I/O modules with their rated input/output voltages being 100VAC and 200VAC systems have a dangerous voltage inside (a
peak voltage of 42.4V or higher). Therefore, for CE-marked I/O modules, reinforced insulation is applied between the primary
and secondary circuits.
I/O modules which operate at 24VDC or lower rated input/output voltage are not targeted for the Low Voltage Directive
compliance.
