Catalog PCC-2/USABasic FeaturesLogicRelays on Stacking SubbasesIndexRELAYSThese components provide additionalcapability to the pneumatic logic system.Types available are: Time Delay, Memory,Amplifier, Sensor, Solenoid, and PressureSwitch (both pneumatic and electric).Depending on function, a 3 or 4-portsubbase is used.ALogic3-PORT SUBBASESThese stackable subbases are designedfor the mounting of:• logic devices• timers• bleed sensor relays• threshold NOT relays• E/P and P/E interfaces.They are stackable with the 4-portsubbases below and are available incommon input or cascade input styles.4-PORT SUBBASESThese stackable subbases are designedfor the mounting of:• memory relays• amplifier relays for use with proximitysensors.They are stackable with the 3-portsubbases above.STACK ASSEMBLYThe drawing to the right explains theprocedure for asembling subbasemounted logic components and relays.Note: The subbases are supplied with anintegral key that must be pulled upward(1) to release the blanking plug (2). Nowthe downstream subbase can bepositioned (3) then locked by returningthe integral key back to its original position(4). After this process is complete,the relay or logic element are mounted ontop.AirPressureSupplyIntegralLocking ofKeythe Key bytheComponent 14BlankingPlug23Pneumatic5Parker Hannifin CorporationPneumatic DivisionRichland, Michigan
