Intentional emissions are exempt from the EMC requirements. But there IS a problem in this area, which is being studied intensively in CISPR and IEC TC77. > >2.

PLC systems have their OWN EMC standards. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero. ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
