D5091S

5 A SIL 3 Relay Output Module for ND Load with ND or NE Relay condition

شرکت GMI که سابقه ای طولانی در تولید بریر و رله های ایمنی دارد، اخیرا مدل های جدیدی را معرفی نموده است که دارای مشخصاتی فراتر از یک رله ایمنی معمولی هستند. این مدل ها دارای قابلیت های کم نظیر و کارامدی جهت استفاده در سیستم های با ضریب اطمینان بالا مانند ESD و F&G می باشند که از جمله می توان به موارد ذیل اشاره نمود:

  •    تشخیص انواع خطاها از بوبین رله تا سطح فیلد مطابق شکل زیر و اعلام نوع خطا از طریق مدباس و خروجی دیجیتال
    •    سازگار با پالس تست DCS/PLC
    •    قابلیت اندازه گیری مقاومت سلونوئید حتی با وجود دیودهای سری شده
    •    اندازه گیری ولتاژ موثر(قبل و بعد از وصل بار) و جریان بار
    •    تشخیص نشتی زمین
    •    قابلیت تعیین set point جهت ولتاژ تغذیه، مقاومت، جریان بار و نشتی زمین

Description

The single channel Relay Output, D5091S is a relay module suitable for the switching of safety related circuits, up to SIL 3 level according to IEC 61508:2010 Ed.2 for high risk industries. It provides isolation between input and output contacts.
Two mutually exclusive (by DIP-Switch programming) monitoring circuits are provided:
1) line input monitoring, to allow DCS/PLC line monitoring function: when enabled, the module permits a wide compatibility towards different DCS/PLC. Driving line pulse testing, executed by DCS/PLC, is permitted by a dedicated internal circuit, to prevent relay and LED flickering.
2) low voltage input monitoring: when enabled, the module reflects a high impedance state to the control unit when the driving voltage is below the specified threshold.

D5091S provides 1 SPDT contact for two different safety functions:
1) SIL 3 Safety Function for Normally De-Energized load (energized in fail safe state)is available at Terminal Blocks 7-8. The driving signal is normally low (0 Vdc),the relay is normally de-energized, contact is open and load is de-energized. The safety function is met when the driving signal is high (24 Vdc),the relay is energized, contact is closed and load is energized. At Terminal Blocks 9-10 is also available a service contact (for service load) with opposite (not SIL) function.
2) SIL 3 Safety Function for Normally De-Energized load (energized in fail safe state)is available at Terminal Blocks 9-10. The driving signal is normally high (24 Vdc), the relay is normally energized, contact is open and load is de-energized. The safety function is met when the driving signal is low (0 Vdc), the relay is de-energized, contact is closed and load is energized. At Terminal Blocks 7-8 is also available a service contact (for service load) with opposite (not SIL) function.

Mounting on standard DIN-Rail or on customized Termination Boards, in Safe Area / Non Hazardous Location or in Zone 2 / Class I, Division 2 or Class I, Zone 2.

Features

  • Systematic capability SIL 3
    • Installation in Zone 2 / Division 2.
    • 1 SPDT contact for 2 different Safety Functions:
    1) SIL 3 for ND load (energized in fail safe state) with ND relay condition (energized in fail safe state)
