The SIL 3 safety relay is for use in the emergency shutdown of plants and plant components in the process industry.
The device meets the requirements of EN61508 as well as the safety demands of Safety Integrity Level 3.
The relay guarantees safe electrical isolation of the safety PLC to the field and initiates protective measures or immediately cuts the energy supply.
In the output of the safety circuit - the SIL circuit - there is a redundant connection of three relays to guarantee reliable isolation within the output circuit.
The relay is fitted with gold-plated contacts and an additional switching current range of 6 mA up to 5 A of the monitoring circuit permanently guarantees reliable reaction of the emergency shutdown system. The time span between relay ON and response is 4.5 ms (230 V AC) and 5.7 ms (120 V AC).
