IntroductionIntroductionIntroductionIntroductionModularinstrumentationhasbeenaroundfor thepast30years,butcontinuestogrowinpopularity.Thesystemshavebecomemorefunctionalwiththeabilityto carry out multiple tasks in parallel. There are many types of modularplatforms: VXI, PXI, PACs, Labview, AXie, USB, GPIB, etc, etc. All theseplatforms have their own bus arrangements and standards. They all offerdifferentadvantagesforagivensetofapplicationsor functions. Theyallofferseveraldifferentplug-inboardsthatcarryoutsingularand/ormultiplefunctions.Several of the plug-in boards require relays to carry out various switchingfunctions. MEDERs relays offer a wide variety of reed relays to meet themultiple usage requirements required in these modular instrumentationsystems.
