SIL 3 Switch/Proximity Detector Repeater, Relay Output

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



The single channel Switch/Proximity Detector Repeater, D5030S module, is a unit suitable for applications requiring SIL 3 level (according to IEC 61508:2010 Ed. 2) in safety related systems for high risk industries.
The unit can be configured for switch or proximity detector (EN60947-5-6, NAMUR), NO or NC and for NE or ND SPST (D5030D) or SPDT (D5030S) relay output contact. Each channel enables a Safe Area load to be controlled by a switch, or a proximity detector, located in Hazardous Area.
Fault detection circuit (DIP switch configurable) is available for both proximity sensor and switch equipped with end of line resistors. In case of fault, when enabled it de-energizes the corresponding output relay and turns the fault LED on; when disabled the corresponding output relay repeats the input line open or closed status as configured.

Mounting on standard DIN-Rail, with or without Power Bus, in Safe Area / Non Hazardous Location or in Zone 2 / Class I, Division 2 or Class I, Zone 2.
