Datasheet SAFESERIES SIL RELAYS SCS Series NEW Safe control of back-up systems The monitoring circuit option takes inputs from 24 to 230 V AC/DC and the safety relay is intended for use in back-up systems or storage tank overfill prevention. Safe control of burner operation Fuel flow to the burner may be cut-off in a boiler alarm condition. SAFESERIES offers a SIL3 fuel cut-off relay which interfaces with the burner management controls. Safe use in corrosive environments The SIL3 relay is also available with a G3 coating, which makes it especially suitable for use in aggressive environmental conditions. Safe activation and deactivation This flexible safety relay can be used in either energize-to-safe or de-energizeto-safe mode. This makes it suitable for use both with actuators which should be powered-on under safe conditions or those which should be powered-off. Weidmuller’s single and dual channel DIN rail-mounted SCS Series are relay modules suitable for switching safety related circuits up to SIL3 level according to IEC 61508, for high risk installations. Typical applications include safety interlocks for burner management systems, over-fill controls for bulk liquid storage tanks and plant shut-down systems. The SCS Series is part of Weidmuller’s broad range of high reliability electronics and electrical connectivity products which services process industries and factory automation systems worldwide. • • • • • SIL relays for process Emergency Shut-Down systems Certified cULus and to IEC 61508 for SIL3 (TÜV) Energized or de-energized to safe modes Single and two-channel models Monitoring options with wide-range input voltage Weidmuller, Canada 10 Spy Court Markham, Ontario L3R 5H6 Telephone: (800) 268-4080 Facsimile: (877) 300-5635 Email: [email protected] Website: www.weidmuller.ca Weidmuller, Mexico Blvd. Hermanos Serdán 698, Col.
