(Formerly known as Union Switch & Signal)Cardfiles (MicroLok II Applications)Rev. 4-11MicroLok II General-Purpose CardfileGeneral-Purpose Cardfile (Single and Dual-Motherboard Models)DescriptionThe General-Purpose MicroLok II System cardfilecontains the system’s central controlling logic andcircuits that interface this logic to external circuits.Logic and interface circuits are contained on thefamiliar Eurocard format plug-in printed circuit boards(PCBs). Two versions of this cardfile are available,including a unit with a single motherboard governed byone CPU PCB, and a unit with dual (identical)motherboards that incorporate separate CPU boardsfor their respective sets of PCBs. The dualmotherboardversion allows two MicroLok IIsubsystems to be housed in one cardfile forapplications such as hot standby, and locations wheretwo single-motherboard cardfiles are not required oradequate space is not available.Both cardfiles contain 19 card slots. All external wiringis connected to the cardfile via 48-pin or 96-pinconnector/cable assemblies attached to connectorsalong the rear of the cardfile. In the typical equipmentrack installation, this wiring is routed to separateadjacent terminal strips.To prevent accidental insertion of a PCB in the wrongcardfile slot, each PCB is equipped with male keyingpins. Dual in-line package (DIP) switches within theconnector housings are used to set the cardfile busaddress for communications between the CPU andother PCBs.The MicroLok II General-Purpose cardfile can bemounted in a standard 19-inch equipment rack, or ona wall or shelf using the fiberglass mounting bracketssupplied with the unit.SpecificationsPCB Design/Mounting:Total PCB Slots:Slot Bus Addressing:Upper PCB Connectors:Mounting:Unit Dimensions:Standard Eurocard19 (both single and dualmotherboardmodels)Via 8-rocker DIP switchesin connector housings48 and 96-pin maleStandard 19” (48.25 cm)rack, wall or shelfSee above diagram.Cardfile Mechanical Loads: 1.0g RMS, 0.2”displacement, 5-1000 HzOperating Temperature:Humidity Limit:-40°C to +70°C (-40°F to+158°F)95%, non-condensing, p. 2

Cardfiles (MicroLok II Applications)(Formerly known as Union Switch & Signal)MicroLok II Intermediate Cardfile for LED Signal LocationsRev. 4-11LED 12 Intermediate System CardfileDescriptionThe MicroLok II LED 12 Intermediate System cardfile usesthe basic Eurocard design, which allows plug-in PCBs toform an complete front control/display panel.
