I would like to get the consensus on the following concept. The low Voltage directive applies to products that use 50VAC or 75VDC and higher signal levels basically up to 1000VAC. Now, If a product's I/O and power signals do not exceed 24Vdc anywhere, does the low voltage directive apply. Here's the catch, the unit contains electrical isolation between input, output and power signals. The electrical isolation rating is specified as 250VAC continous.
Some argue, that since the unit is isolated and has an isolation rating the Low voltage directive applies because the isolation specification exceeds 50VAC. You can also argue that within the scope of the Low Voltage directive that the I/O and power signals are below the directives requirement and hence do not apply if you don't consider whether the product has electrical isolation or not. Does the fact that electrical isolation is included into a product, affect whether the Low Voltage Directive may or may not apply? Best Regards, Gary Labadie Marketing Acromag, Inc. 30765 Wixom Rd.
