Code: D1092D
Name: 2 Ch, Relay Output Module for NE and ND loads, SIL3
Type: Relay Output
Channels: 2
Description: The single and dual channel DIN Rail Relay Output, D1092S and D1092D are relay modules suitable for the switching of safety related circuits, up to SIL 3 level according to IEC61508, for high risk industries.
It provides isolation between input and output contacts. D1092D provides 2 SPST contact for normally energized loads and 2 SPST contact for normally de-energized loads.
When the relay is energized, the contacts are closed. When the relay is de-energized, the contacts are open.
Function: SIL 3 Safety Function NE load (de-energized in safe state) is available at Terminal Blocks 1-2 and Terminal Blocks 5-6; in this case, the safety function is met when the relays are de-energized (open contact). SIL 3 Safety Function for ND load (energized in safe state) is available at Terminal Blocks 3-4 and Terminal Blocks 7-8; in this case the safety function is met when the relays are energized (closed contact).
Features:
• SIL 3 according to IEC 61508 for Tproof = 10 / 20 years (10 / 20 % of total SIF) with NE Load.
• SIL 3 according to IEC 61508 for Tproof = 7 / 15 years (10 / 20 % of total SIF) with ND Load.
• PFDavg (1 year) 7.01 E-06, SFF 99.13 % with NE Load.
• PFDavg (1 year) 1.14 E-05, SFF 97.95 % with ND Load.
• Installation in Zone 2, Division 2.
• 2 fully independent channels.
• 1 SPST contact for NE load and 1 SPST contact for ND load for each channel.
• Input/Output isolation.
• EMC Compatibility to EN61000-6-2, EN61000-6-4.
• ATEX, FM & FM-C Certifications.
• TUV Certification for SIL.
• High Reliability, SMD components.
• High Density, two channels per unit.
• Simplified installation using standard DIN Rail and plug-in terminal blocks.
SIL Levels: D1092D, according IEC 61508 & IEC 61511, is suitable for applications up to safety integrity level SIL 3 . |
