Based on the REYROLLE Multi-Function platform our new generation of integrated transformer protection relays are designated the 7SR24 series. The 7SR242 is dedicated to protect 2-winding transformers.

The relay is the latest development of transformer protection relays and utilizes years of numeric relay protection experience with the ‘DUOBIAS’ family of products. Housed in 4U high, size E8 or E10 cases, these relays provide protection, control, monitoring, instrumentation and metering with integrated input and output logic, data logging & fault reports.

Communication access to relay functionality is via a front USB port for local PC connection or rear electrical RS485 port for remote connection. Additional rear port options are available.
