Optocouplers |

Optocouplers are composed of two circuits: an input circuit and an output circuit. A light emitting diode (LED) is the key input component, where the key output component is a photo-detector. Passing a current of approximately 10 ma through the two input terminals and through the light emitting diode, with the correct polarity, converts the electrical current into photons. The photons are then directed down a light tube or tunnel. At the end of the tunnel, the photons are incident on the photo detector that converts the photons back to an electric current. In this manner, the input information is transferred and amplified in the output detection circuit without any direct electrical conducting path. The longer the light tube the greater the distance between the metalized input terminals to the metalized output terminals. This insures a greater insulation resistance and high voltage isolation. Optocouplers handle hazardous environments and meet ATEX intrinsic safety requirements. Our line of optocouplers can safely handle input/output isolation as high as 20,000 VDC that have met and been certified for the stringent requirements of ATEX (Directive 94/9/EC and 1999/92/EC). This directive applies to equipment and protective systems that are used in factories where potentially explosive atmospheres exist such as in mining operations, flammable gas processing plants, some medical processing plants where ESD could be a real problem, and in any factory that requires high isolation and non-arcing environments.
