In addition to providing high-speed connectivity directly to your Universal Relay, the UR Switch Module provides an additional 4 fiber Ethernet ports, for connection to other relays in the system as well as upstream connectivity. It also provides 2 RJ45 copper Ethernet ports which can be used to connect local devices such as PCs, meters, or virtually anything else in the system.
The UR Switch Module provides a simple way to add fully-managed Ethernet networking to your relays and devices without the need for additional hardware or a dedicated communications cabinet.
The UR Switch Module includes all of the management and features that come with all MultiLink managed switches, and can be easily integrated into a network that has other Ethernet switches.
When used in a ring topology with other UR Switch Modules or MultiLink Switches, the UR Switch Module can be configured to use MultiLink’s Smart RSTP feature to provide industry-leading network recovery for ring topologies, at a speed of less than 5ms per switch. Learn More

CyberSentry enables UR devices to
deliver full cyber security features that help customers to comply with NERC CIP and NITIR 7628 cyber security requirements through supporting the following core features:
Supporting up to 20 alpha- numeric or special characters, UR passwords exceed NERC CIP requirements for password complexity. Individual passwords per role are available.
AAA Server Support (Radius)
Enables integration with centrally managed authentication and accounting of all user activities and uses modern industry best practices and standards that meet and exceed NERC CIP requirements for authentication and password management.
Role Based Access Control (RBAC)
Efficiently administrate users and roles within UR devices. The new and advanced access functions allow users to configure up to five roles for up to eight configurable users with independent passwords. The standard “Remote Authentication Dial In User Service” (Radius) is used for authentication.
Event Recorder (Syslog for SEM)
Capture all cyber security related events within a SOE element (login, logout, invalid password attempts, remote/local access, user in session, settings change, FW update, etc), and then serve and classify data by security level using standard Syslog data format. This enables UR devices integration with established SEM (Security Event Management) systems.
The EnerVista™ suite is an industry-leading set of software programs that simplifies every aspect of using the D60 relay. The EnerVista™ suite provides all the tools to monitor the status of the protected asset, maintain the relay, and integrate information measured by the D60 into DCS or SCADA monitoring systems.
