NB-GPCFHC是BACnet标准的实验室通风柜控制器，能够支持多种操控方式，包括面风速、移门位置、hot wire、vortex shedding等。配合AAM的FHC-SD全彩触屏控制面板，能够多层级管理及使用历史存档等功能。The NB-GPCFHC is a Native BACnet controller utilizing American Auto- Matrix GPC Technology. The NB-GPCFHC in combination with the FHC-SD color touch-screen local user interface offers unprecedented technology combined with flexibility of control found nowhere else in the industry today.Through utilizing the NBC-GPCFHC fume hoods can be configured to support a number of control methodologies including face velocity hot wire vortex shedding and sash position methods through a single controller. In addition flexibility is expanded through the use of theFHC-SD a color touch-screen display that offers multiple levels of configurability and accessibility; designed to give users security and safety on a highly visible live local user interface.FEATURESPatented closed loop control based on measured face velocity technology or control based on popular Venturi-type valves and single sash area calculationsMicroprocessor-based DDC control system utilizing tunable high speed PID (Proportional Integral Derivative) control algorithms or fuzzy logic algorithmsHigh speed PID algorithms calculate control outputs up to (or as fast as) every 50msCan be used in stand-alone or networked environmentsProgrammable occupancy set points and schedules allow target face velocity to be lowered when the hood is not in usePluggable wiring connectionsPre-programmed function blocks improve application reliabilityBACnet MSTP communication over twisted pair (EIA 485) wire; up to 115.2k Baud(current BACnet standard allows up to 76.8K)Plug and play flow totalization for flow offset control independent of BAS networkDigital output allows the incorporation of external alarmingSupports non-linear input and output curves for seamless thirdparty sensor/damper integrationTwo stage programmable low/high alarmsBattery backup for configuration data and real-time clockEmergency mode drives damper to configurable output positionSupplied with approved lockable enclosureSPECIFICATIonSGeneral SpecificationsTerminationspluggable blocks for inputs outputs power & network connectionWiring18-22 gauge wireInput Supply22-29 VAC 50/60 Hz @ 4.16A max PTC protectionTransformerinternal isolated switching power supplyIndicatorsLEDs for line power regulated DC voltagesInputs & Outputs5 Dedicated Inputs1 Face Velocity Input1 Exhaust Flow Input1 Fume Hood Air Valve Pressure Input1 Emergency Input (Dry Contact)1 Sash Position Input1 Dedicated Serial InputCascade Flow Input1 Dedicated Analog OutputExhaust Flow Damper Output (0-10 VDC 0-20 mA)1 Dedicated Digital OutputAlarm Device Output(10-29 VAC 1A Opto-isolated triac)1 Dedicated Serial OutputCascade Flow Output1 Expansion Digital InputHood Presence Input or Enable/Diable Input (optional SSB-UI1)1 Expansion Digital OutputHood Lighting Output (optional SSB-D01)Operating ConditionsOperating Temperature32˚ to 122˚ F (0˚ to 50˚ C)Relative Humidity0 to 90% relative humidity non-condensingDimensions/MountingApproximate Dimensions8.2 x 6.5 x 1.0 inches / 1 lb (not including shipping material)Mountingflat surface with screwsAgency ApprovalsComplies with CE directives and standardsFCC - Class B Computing Device; Part 15UL Listed 916 - Management Equipment Energy (PAZX)Patent InformationAmerican Auto-Matrix products and systems are manufactured and installed under one or more of the following US patents and/or others that may apply.5764579; 6272399; 5920488; 5946221; 5481919; 5402687; 5415583BTL ListedAAM HAS OVER 30BTL LISTEDCONTROLS##
