Advanced Communications

Easy integration into new or existing infrastructure

With several Ethernet and serial port options, and a variety of communication protocols, the 3 Series provides advanced and flexible communication selections for new and existing applications.

The 3 Series supports various industry standard protocols such as, IEC 61850, Modbus RTU, Modbus TCP/IP, DNP3.0, IEC 60870-5-103 and IEC 60870-5-104 providing simplified and easy integration into new and existing applications.

Drawout Construction 

The 3 Series offers a complete drawout feature eliminating the need for rewiring after testing has been concluded. With our advanced draw-out construction, the 3 series can be drawn-out without having to disconnect any communication cables. e.g. fiber, copper, RJ45, etc and helps retain communication status even after a relay has been withdrawn from its case.

Security - enabling NERC CIP compliance

Access Control 

Multilin devices and relays are designed with simple but powerful security to enable reliability and compliance for virtually any project or implementation. With support for multi-level permissions and multi-factor supervisory controls, Multilin devices can help you manage the integrity of your system during commissioning, testing, implementation, and beyond. The 3 Series family provides separate authentication for settings and commands to the system. In addition, as discrete authentications for local and remote access, it also provides a supervisory control factor that can lock or unlock a device for configuration changes and other modifications.

Intrusion Detection

Multilin’s family of protection and control products can also help enable your security perimeter and intrusion detection programs. By providing essential alarming and logging of critical events, Multilin devices can help you detect potential breaches within your system and allow you to respond quickly and effectively. Specifically, unsuccessful access attempts are logged, alarmed, and lead to potential attackers being locked out. This ensures the reliability of your system during questionable activity control factor that can lock or unlock a device for configuration changes and other modifications.

Monitoring & Diagnostics

The UR includes high accuracy metering and recording for all AC signals. Voltage, current, and power metering are built into the relay as a standard feature. Current and voltage parameters are available as total RMS magnitude, and as fundamental frequency magnitude and angle.

Advanced Automation

The UR incorporates advanced automation features including powerful FlexLogic™ programmable logic, communication, and SCADA capabilities that far surpass what is found in the average protection relay. Each UR can be seamlessly integrated with other UR relays for complete system protection and control.

Key Features

• Complete IEC 61850 Process Bus solution providing resource optimization and minimizing total P&C life cycle costs
• Three independent 100Mbps Ethernet ports enable purpose specific LAN support that reduces latency effect of heavy traffic protocols on mission critical communication services
• Embedded IEEE 1588 time synch protocol support eliminates dedicated IRIG-B wiring requirements for IEDs
• Direct I/O secures high-speed exchange of binary data between URs
• Increase network availability by reducing failover time to zero through IEC62439-3 “PRP” support

Advanced Communications

The UR provides advanced communications technologies for remote data and engineering access, making it easy and flexible to use and integrate into new and existing infrastructures. Direct support for fiber optic Ethernet provides high-bandwidth communications allowing for low-latency controls and high-speed file transfers of relay fault and event record information. The available three independent and redundant Ethernet options provide the means to create fault tolerant communication architectures in an easy, cost-effective manner. The UR supports the most popular industry standard protocols enabling easy, direct integration into DCS and SCADA systems.

Cyber Secutrity - CyberSentry™ UR (FW v7.4xx)

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:

Secure FW upgrade

UR FW files v7.9 and up now include a hash code that allows for authentication prior to being used for upgrading UR devices

Password Complexity

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.

EnerVista™ Software

The EnerVista™ suite is an industry-leading set of software programs that simplifies every aspect of using the UR. The EnerVista™ suite provides all the tools to monitor the status of the protected asset, maintain the relay, and integrate information measured by the UR into DCS or SCADA monitoring systems. Convenient COMTRADE and Sequence of Events viewers are an integral part of the UR setup software included with every UR relay, to carry out postmortem event analysis and ensure proper protection system operation.
