رله حفاظتی جی ام اینترنشنال D5090S GMI SIL3 - NE Loads

رله ایمنی مدل D5090S برای کاربردهای NE (Normally Energized)

General Description:(توضیحات کلی)
The single channel Relay Output,(رله خروجی تک کانله) D5090S is a relay module suitable for the switching(مناسب برای تعویض) of
safety related circuits(مدارهای مربوط), up to SIL 3 level according to IEC 61508:2010 Ed.2 for high risk
industries.(صنایع پرخطر)
It provides isolation between input and output contacts.(بین رابط ورودی و خروجی را مجزا میکند)
Three 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(ولتاژ پایین) input monitoring: when enabled, the module reflects a high impedance
state to the control unit when the driving voltage is below the specified threshold.
3) short circuit fault detection: when enabled, it allows DCS/PLC to detect short circuit
fault of module.
D5090S provides two NO contacts for normally energized load and a NC contact for
service purpose, in order to switch the NE load on both supply lines.
