Catégory D1 /C1 /C2 /C3 surge protector D9510S

SIL 3 Surge Protective Device for Signal System Model D9510SD9510S provides two-stage surge protection for floating I/O two-wire 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. It consists of a protective plug and a base element. 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.Signal not interrupted during maintenance work, thanks to impedance neutral insertion and removal of protective plug.High Density, 6.2 mm per channel.HART compatible.Technical Specifications:Supply:Nominal system voltage Un: 24 V DCMax continuous operating voltage Uc: 30 V DCRated current: 600 mA (40°C)Protection:IEC test classification: C1 / C2 / C3 / D1Protection of signal types: 0/4-20 mA HART, Digital I/O, World FIP, F&GNominal discharge current (In): (8/20) μs: 5 kA (core-core) 5 kA (core-ground)Impulse discharge current (Iimp): (10/350) μs: 0.5 kA (core-core) 0.5 kA (core-ground)Total discharge current (Itotal): (8/20) μs: 10kAMax. total discharge current (Imax): (8/20) μs: 20kA (for one time)Series resistance: 1.65Ω ± 20%Voltage protection level (Up): ≤ 55 V (C1 - 1 kV/500 A) core-core; ≤ 65 V (C2 - 10 kV/5 kA) core-core; ≤ 55 V (C3 - 100 A) core-core; ≤ 900 V (C1 - 1 kV/500 A) core-ground; ≤ 1.05 KV (C2 - 10 kV/5 kA) core-ground; ≤ 1.4 KV (C3 - 100 A) core-groundResponse time tA: ≤ 1 ns (core-core), ≤ 100 ns (core-ground)Environmental conditions:Operating temperature: –40 to +85 °CRelative humidity: 5% to 95%Mounting:Type: EN/IEC60715 TH 35 DIN-RailWeight: about 42 gConnection: screw terminal blocks to accommodate terminations up to 2.5 mm2 flexibleLocation: installation in Safe Area or Zone 2 or Zone 1, Group IIC T4...T6Protection class: IP20Dimensions: Width 6.2 mm, Depth 100 mm, Height 105.8 mmCertifications:ATEX: DEKRA ATEX D9410, D9420, D9510, D9520 Series English Certificate (BVS 18 ATEX E 018 X, DEKRA, 2022-07-12)IECEx: DEKRA IECEx D9410, D9420, D9510, D9520 Series Certificate (IECEx BVS 18.0012X, DEKRA, 2022-07-18)SIL: EXIDA GM 17/11-006 R008 Analysis for SIL Application D9510S, D9520S (GM 17/11-006 R008, EXIDA, 2018-03-28)Declarations of Conformity:EU Declaration of Conformity for D9410, D9420, D9510, D9520
