VMO SeriesDATA/SIGNAL LINES PROTECTIONIEC category / EN type: D1/C1/C2/C3 (IEC 61643-21)Design: Replaceable plug-in moduleMode of protection:Longitudinal, TransverseCoarse Protection: 2 x 2 terminal GDT,1 x 3 terminal GDTAvailable voltages: 5, 12, 15, 24, 30, 48, 60 V DC, 110VACFreq: 0.6 - 3 MHz (see specification sheet)Surge Discharge Ratings: I n: 20kA 8/20µs, I max: 30kA 8/20µsSeries load current:1AEnclosure:DIN 43880 1TE, DIN rail mountTerminals:Multi-strand to 6 mm 2The VMO series of low voltage protective devices has been developed to protect against the effects of inducedvoltages onto data, signal and communication circuits.It is intended for those applications where higher than normal surge discharge levels may be experienced.Coarse protection is provided by 2, two terminal gas discharge tubes. A second stage of protection is providedusing a three terminal gas discharge tube which assists in common mode protection.Fine protection is provided using a high speed silicon avalanche diodes or metal oxide varistor stage. Care is takento ensure coordination between these two stages without voltage or surge current blind spots occurring.Both common (longitudinal) mode and differential (transverse) mode protection is provided.Technical characteristicsTypeProtection constructionNumber of protected pairsNominal operating voltageMax. continuous operating voltageRated spark overvoltageUnUc(a/b-PG)(a-b)Rated operating current at 25oCI LNominal discharge current (8/20µs) I nMax. discharge current (8/20µs) ImaxLightning impulse current (10/350µs) IimpResidual voltage at 5 kA (8/20µs)Response time of overvoltage protection t AInsulation resistance of the protectionSerial resistance RTransverse capacitance CLimit frequency f GTerminal cross sectionOperating temperatureDegree of protectionHousing materialDimensions DIN 43880Mounting EN 60715Ordering code Base + Replaceable plug-in moduleReplaceable plug-in module5V5V DC7V DC6.5 - 9V6.5 - 9V1A20kA30kA5kA< 20V< 1ns≥ 6K Ωca 2Ω7nF0.6MHz702 505702 50412V12V DC15V DC16 - 20V16 - 20V1A20kA30kA5kA< 39V< 1ns≥ 15MΩca 2Ω4.5nF0.9MHz702 508702 507VMO15V 24V 30V 48VTwo parts: base + replaceable plug-in module1 (2 conductors)15V DC18V DC20 - 24V20 - 24V1A20kA30kA5kA< 45V< 1ns≥ 18M Ω702 511702 51024V DC28V DC30 - 36V30 - 36V1A20kA30kA5kA< 65V< 1ns≥ 28M Ω30V DC33V DC35 - 43V35 - 43V1A20kA30kA5kA< 77V< 1ns≥ 33MΩon a 35mm DIN rail702 514 702 517702 513 702 51648V DC52V DC55 - 68V55 - 68V1A20kA30kA5kA< 135V< 1ns≥ 52M Ωca 2Ω3.3nF1.1MHzca 2Ω2.9nF1.4MHzca 2Ω2.1nF1.8MHzca 2Ω1.2nF2.2MHzMulti-strand to 6 mm 2- 40oC ... + 80oCIP 20Thermoplastic; yellow, extinguishing degree V-O1TE702 520702 51960V60V DC64V DC67 - 85V67 - 85V1A20kA30kA5kA< 150V< 1ns≥ 64MΩca 2Ω1.0nF3.0MHz702 523702 522110 V110V DC170V DC184 - 264V184 - 264V1A20kA30kA5kA< 450V< 25ns≥ 170MΩca 2Ω150pF10Mhz702 502702 501www.iskrazascite.si27
