What is the difference between an active and a passive barrier?
B
Barry Latiolais
An active barrier must have a power source to activate the electronic circuit within the unit.The signal is then transferred through an
isolation principle (Ie
ptical or transformer coupled.)A passive barrier will pass signals through as long as all paramaters are met.Be
cautious about your end devices as they cannot contain energy storing devices.Active barriers are your better choice in todays world.
