(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. Severalmodels of plug-in PCB cardfiles that accommodate Ethernetor serial communications to a remote wayside system ofoffice, as well as A<strong>STS</strong> USA or Alstom style VCOR relayoptions for vital power switching.This cardfile incorporates an extended backplanemotherboard with 12 front-accessible cage clampconnectors (Wago brand) that enable direct connection ofexternal I/O wiring to the cardfile. The arrangementeliminates the need for separate rack-mount terminal stripsand/or connector cable assemblies. To aid in field wiring,the connectors are assigned (as labeled) to specific types ofPCBs. Slot-address jumpers for the LED 12 and trackcircuit PCBs (MicroTrax and E-Code) are also located onthe motherboard. Additional jumpers allow for inputs to theLED 12 boards to be shorted together to support ConstantCurrent Regulator (CCR) sharing between LED signaloutputs, without the use of additional external wiring.Other motherboard-mounted devices include and EEPROMfor storing unit-specific configuration data, top-mounted RJ-45 jack for Ethernet communications wiring, and two 25-pin“D” connectors to interface vital or non-vital serialcommunications wiring (when required) to the CPU PCB’sserial ports. These ports also permit daisy-chaining ofseveral LED 12 systems. AREMA (AAR) terminal posts arealso provided for connection of power input wiring (includeswired-in transient voltage protection). These terminals,which incorporate post-to-post straps, are also used toroute VCOR-controlled power and CCR power when theLED 12 PCB is installed.The VCOR relay is housed in the left-hand bay of thecardfile and includes a built-in relay base. Thisarrangement eliminates the need for a separate VCOR rackinstallation outside the cardfile. Both A<strong>STS</strong> USA PN-150Band Alstom B1 relays are provided in the various cardfileoptions (see Ordering Information).Several models of the MicroLok II LED 12 System cardfileinclude an Ethernet Communications Module (ECM) that isstand off-mounted on the back side face of themotherboard. Ethernet communications are enabledthrough Port 4 on the CPU PCB and the Ethernet jack at thetop of the cardfile. Versions of the cardfile not equippedwith the Ethernet capability can be upgraded in the field at alater date by installing the ECM as an add-on component.SpecificationsPCB Design/Mounting:Total PCB Slots: 8Cardfile Connectors:Unit Dimensions:Cardfile Mounting:Cardfile Weight:Operating Temp.:Humidity Limit:Standard Eurocard12 cage clamp connectorsRJ-45 Ethernet Jack (8-pin)2 25-pin “D” connectors (seriallinks)5 AREMA (AAR) terminal postsSee above diagram.Rack or wall (see OrderingInformation)30 lbs.
