THE RANGE


CLEARSY vital RS4.DIN.202.24V safety relay featuring 2 NO contacts guaranty on opening with a SIL4-level is a success. This success led us to add new vital RS4 models to form a range for various railway applications. For on board application the new 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.

The RS4.DIN.202.24V can be used on board or track side for signaling projects. The relay features 2 inputs ( 0 to 18Ω and 18 to 45Ω) to take into account the wire impedance connected between the relay command and the relay. The relay provides 2 NO contacts guaranty on opening with a SIL4-level and 2 NC contacts. This relay is also available in 3U-card format with two independent 202 relays. This relay version provides 4 NO contacts guaranty on opening with a SIL4-level and 4 NC contacts.
