The D1000 & D5000 Series SIL 3 Relays are available in various contact configurations and rating to cover the majority of applications; they are available with standard DC as well as with AC coil. Typical applications are shutdown or relief valves control, Fire & Gas valve control, Turbine shut down, AC/DC motors control center, etc.
In high integrity applications, whether it is for a ESD, F&G, BMS or for any other critical application, a Safety (SIL 3) Relay must be used.
For each application the specific Safety Function must be determined to select the correct Safety Relay. The Safety Function controls the operating condition of the SIF, therefore of the Safety Relay.
