Siemens launches Reyrolle 5 protection relay series

The new Reyrolle 5 protection device series. 

As digitalization increases, a protection device must ensure a secure electricity infrastructure. The Reyrolle 5 includes cyber security features such as digitally signed firmware and these will be further enhanced with future product releases along with security patches to address any specific threats. Reyrolle 5 offers an intuitive design with a large graphical display, tactile pushbuttons, programmable LEDs, and the user-friendly, next-generation Reydisp software. The protection relay already provides comprehensive functionalities like wide-range power supply, configurable digital input thresholds, current and voltage transformer connections, and serial and Ethernet communication. All communications protocols are also included as standard. 
Thanks to its withdrawable design, Reyrolle 5 can be easily replaced without disturbing the switchgear connections. This reduces downtimes to a minimum and enables reliable and efficient lifecycle management. 
Siemens already has more than 2.5 million numerical Intelligent Electrical Devices (IEDs) installed worldwide, thereof approximately half million of the Reyrolle protection relay series. The Reyrolle 5 protection solution builds on more than 100 years of history of developing protection relays with proven algorithms to ensure reliable performance.
