P.T.O.instabus®Technical ManualSolar protection actuatorJB520C235WG1520-4CB23April 2020 / Page 1Product and Applications DescriptionThe JB520C23 solar protection actuator is a KNX device withone relay output. The device is installed in a 4 x 4 inch junc-tion box. The bus is connected via a bus terminal block. Theactuator electronics are supplied via the bus voltage.The JB520C23 may be used to control blinds, shutters, awn-ings, windows, or doors.The device is designed to drive (per channel) one AC 120Vdrive (motor) with electromechanical limit switches or withintegrated electronics for disconnection at the limit positions.For drives with electromechanical limit switches the actuatorcan be configured to detect the status of the electromechan-ical limit switches such that the travel time between the endpositions can be measured via a synchronization run. Thetravel time of the blind / shutter is automatically measuredfrom the upper end position to the lower end position andvice versa. The measurement is only reliable for drives withelectromechanical limit switches. The travel time cannot beautomatically adjusted for drives with integrated electronicsfor disconnection at the limit positions. These drives have tobe controlled via a time limit. Their travel times have to bemanually measured as precisely as possible and configured inthe application program.Parallel operation of several drives on one channel requiresusing a special separation relay. If such a separation relay isconnected to the output to drive several drives in parallel,then the travel time has to be configured manually.If the device is configured for automatic detection of thetravel time, then parallel operation of several drives with elec-tromechanical limit switches or mixed operation with driveswith integrated electronics for disconnection at the limit po-sitions is not permitted.Application ProgramThe JB520C23 Solar protection actuator (JB module) needsthe application program"07 B0 A1 Shutter Actuator 982A01“.Example of OperationK1DownBus coupling un itinstabu s KN X Shutter / blind actuator JB520/23K2UpLoad circuitAC V120N PEL1UpDown124 NM1~Venetianblind motor3 LDetectionof endpositionChannel ATechnical SpecificationsPower supply• via the bus line• KNX bus voltage:DC 24V (DC 21...30V) via KNX/EIB bus line• KNX bus current: < 10 mAOutputs• Mains connection:carried out via the terminals for L and N of the actuator• 1 drive channel with 2 relay contact outputs,- rated voltage: AC 120 V, 50/60 Hz• rated current: 6A (resistive load)• switching current at DC 24 V:- 6 A resistive load,- 4 A inductive load (L/R = 7 ms)Maximum load6 A @ 120 Vac (General Purpose)Control elements1 learning button:for switching between normal operating mode andaddressing modeDisplay elements1 red LED:for monitoring bus voltage and for displaying normalmode/addressing modeConnections• Bus line : Bus connection pins for connection of thescrewless bus terminal block (red-black) 0.6…0.8 mmØ single core, strip insulation 5mm• Load circuit:see Location and Function of Interface ElementsPhysical specifications• housing: plastic• dimensions (L x W x D):length : 70 mm (2.76 inch)width : 90 mm (3.54 inch)depth: 44.6 mm (1.76 inch)• weight: approx 198 g• fire load: approx. 5 MJ• Installation: in a junction box (min. dimensions (L-W-D))Length: 4 inch (101.6 mm)Width: 4 inch (101.6 mm)Depth: 2 inch (50.8 mm)Electrical safety• Degree of pollution (according to IEC 60664-1): 2• Type of protection (according to EN 60529): IP 20• Overvoltage category (according to IEC 60664-1): III• Bus: safety extra low voltage SELV DC 24 V• Device complies with: EN 50428Electromagnetic compatibilitycomplies with EN 50428Environmental specifications• Ambient operating temperature:- 5 … + 45 °C (+ 23 ... + 113 F)• Storage temperature:- 25 … + 70 °C (- 13 ... + 158 F)• Relative humidity (not condensing): 5 % … 93 %Reliability• Failure rate: 632 fit at 40°CMarkingsEIB, KNX, ULListings and CertificationsCE markcomplies with the EMC regulations (residential and func-tional buildings) and low voltage regulationsUL listed (E464611)UL 916, Open Energy Management EquipmentUSA
