Hi,

On a product with a PNP output (24V 200mA) what extra circuit components are required before interfacing the collector of the PNP transistor to the outside world in an industrial environment? I'm thinking in regards to EMC requirements (surge, burst, ESD), is there a 'tyipical' circuit? or a list of standard recommendations for robust design?

Thanks,
nodee
