The REL15017 is a protection relay designed for medium voltage applications. It features a power supply range of 90-250V and includes three current transformers (3CT). The relay offers one input (1Io) with a sensitivity adjustable from 0.05 to 12 times the nominal current (IN), along with eight digital inputs (8DI) and six digital outputs (6DO). It supports communication via RS485 and USB interfaces, making it suitable for integration into automation and monitoring systems. This relay is typically used in feeder protection schemes to ensure reliable operation of electrical distribution networks.
