Catégory D1 /C1 /C2 /C3 surge protector D9420S

SIL 3 Surge Protective Device for Signal System Model D9420SD9420S provides two-stage surge protection for floating I/O three wires signals of measurement and control and safety systems. With a width of 6mm, it can be easily fitted into any marshalling cabinets or distribution cabinets. The SPD provides surge protection with 1.65Ω loop impedance, with disconnect knife on both signal paths for easy testing of the loop.SIL 3 according to IEC 61508:2010.Input from Zone 0 (Zone 20), installation in Zone 1 and 2.Disconnection of signal circuit by disconnect knife.Signaling without additional auxiliary power, thanks to the mechanical status indicator.High Density, 6.2 mm per channel.HART compatible.Technical DataSupplyNominal system voltage Un24 V DCMax continuous operating voltage Uc30 V DCRated current600 mA (40°C)ProtectionIEC test classificationC1 / C2 / C3 / D1Protection of signal types0/4-20 mA HART, Digital I/O, World FIP, F&GNominal discharge current (In)(8/20) μs: 5 kA (core-core) 5 kA (core-ground) 5 kA (core-earth)Impulse discharge current (Iimp)(10/350) μs: 0.5 kA (core-core) 0.5 kA (core-ground) 0.5 kA (core-earth)Total discharge current (Itotal)(8/20) μs: 10kAMax. total discharge current (Imax)(8/20) μs: 20kA (for one time)Series resistance1.65Ω ± 20%Voltage protection level (Up)≤ 150 V (C1 - 1 kV/500 A) core-core≤ 275 V (C2 - 10 kV/5 kA) core-core≤ 55 V (C3 - 100 A) core-core≤ 750 V (C1 - 1 kV/500 A) core-ground≤ 750 V (C2 - 10 kV/5 kA) core-ground≤ 1.2 KV (C3 - 100 A) core-ground≤ 80 V (C1 - 1 kV/500 A) core-earth≤ 125 V (C2 - 10 kV/5 kA) core-earth≤ 55 V (C3 - 100 A) core-earthResponse time tA≤ 1 ns (core-core) ≤ 1 ns (core-ground) ≤ 100 ns (core-earth)Environmental conditionsOperating temperaturetemperature limits –40 to + 85 °C, relative humidity 5% to 95%.MountingTypeEN/IEC60715 TH 35 DIN-Rail.Weightabout 60 g.Connectionscrew terminal blocks to accommodate terminations up to 2.5 mm2 flexible.Locationinstallation in Safe Area or Zone 2 or Zone 1, Group IIC T4...T6.Protection classIP20.DimensionsWidth 6.2 mm, Depth 83.5 mm, Height 105.8 mm.CertificationsATEX: DEKRA ATEX D9410, D9420, D9510, D9520 Series English Certificate (Europe) - BVS 18 ATEX E 018 X, DEKRA, 2022-07-12IECEx: DEKRA IECEx D9410, D9420, D9510, D9520 Series Certificate (International) - IECEx BVS 18.0012X, DEKRA, 2022-07-18SIL: EXIDA GM 17/11-006 R007 Analysis for SIL Application D9410S, D9420S (International) - GM 17/11-006 R007, EXIDA, 2018-03-28Declarations of ConformityEU Declaration of Conformity for D9410, D9420, D9510, D9520Characteristics / Technical SpecificationsModel: D9420SCategory: Surge protection for I/O signals and SignalingWidth: 6.2 mmNominal system voltage: 24 V DCMax continuous operating voltage: 30 V DCRated current: 600 mA (40°C)Series resistance: 1.65Ω ± 20%Protection class: IP20Mounting: EN/IEC60715 TH 35 DIN-RailWeight: about 60 gOperating temperature: –40 to +85 °CDimensions: 6.2 x 83.5 x 105.8 mm
