At Digital and Smart Grid Enterprises, we offer Hitachi Energy’s Supervision & Signalling relays for reliable substation monitoring and operational visibility. The RXSF signal flag relay is a general-purpose DC signalling relay with a red or yellow mechanical flag that indicates protection operation.
It supports trip-current indication, intertrip signalling, remote indication, and DC supply voltage supervision through its zero-voltage version. Moreover, its high AC surge immunity and twin contacts ensure reliable operation, even at low voltages. Available in DC voltage- and current-operated versions, it offers armature-following or manually reset flags, low power consumption, and strong resistance to shock and vibration.
