GE UR9TA High-Performance CPU Module

Product Overview

The GE UR9TA is an advanced Central Processing Unit (CPU) module engineered for the GE Multilin Universal Relay (UR) platform. Built around a high-speed 32-bit RISC processor running at 132 MHz, the UR9TA is the primary intelligence engine for executing sub-cycle protection algorithms and complex FlexLogic™ sequences.

Key Features and Engineering Advantages

• Rapid Processing & Decision Making: The 132 MHz architecture allows for instantaneous evaluation of fault conditions, ensuring high-speed tripping and reclosing for critical transmission and distribution assets.

• Hot-Swappable Design: To maximize system availability, the UR9TA can be replaced while the relay chassis remains powered. This allows for rapid hardware updates or maintenance without taking the entire protection scheme offline.

• Advanced Cybersecurity: The integrated CyberSentry™ suite provides a layered defense-in-depth approach, including secure passwords and audit trails to assist utilities in maintaining NERC CIP compliance.

• Precision Network Coordination: Support for IEEE 1588 (PTP) ensures that the relay is synchronized with the rest of the substation network to within microsecond accuracy, which is essential for accurate synchrophasor data and event logging.

• Exceptional Thermal Efficiency: Consuming less than 4 W of power, the UR9TA generates minimal heat, allowing it to operate reliably up to +80°C in unconditioned outdoor control cabinets.

• Comprehensive Protocol Suite: Facilitates easy integration into any SCADA or DCS system via Ethernet or Serial links using universal protocols like DNP3 or Modbus.
