The vital 202 relay features 2 NO contacts SIL4-guaranteed to open and 2 NC contacts (model 72\/110V).<\/p>\r\n

RS4 safety relays feature Normally Open (NO) contacts guaranteed on opening with the highest safety level, SIL4, and Normally Close (NC) contacts. These contacts are weld no transfer, compliant with EN 61810-3 Type A (forced guided contacts). They are available in several command voltages, mounting interfaces and NO and NC contacts configurations.<\/span><\/p>\r\n

Certified EN 50155, RS4 vital relays are suited for train on-board applications.<\/span><\/span><\/span><\/p>\r\n

For on board application the RS4.DIN.202.110V, certified EN 50155, features 2 NO contacts guaranty on opening with a SIL4-level and 2 NC contacts. Its command voltage input is 110VDC.<\/p>\r\n

This safety relay is also available in 3U-card format with two independent 202 relays (24V). This safety relay version provides 4 NO contacts guaranty on opening with a SIL4-level and 4 NC contacts.<\/em><\/p>\r\n

For trackside application, like signalling project, theRS4 safety relays (except the 110V version)\u00a0 feature two voltage inputs to accommodate the impedance of the connection between the command of the RS4 safety relay and the safety RS4 relay: 0 to 18\u03a9 and 18 to 45\u03a9.<\/span><\/p>\r\n

This double input allows to use the relays in post or in line with the same relay reference (except the 304 which has two references).<\/p>\r\n
