The UR9EH (Model: UR9EH) is a high-precision Analog Output Module (AOM) designed for the GE Multilin Universal Relay (UR) series. This module serves as the primary interface for transmitting calculated system parameters—such as real-time power, frequency, or load levels—from the relay’s internal logic to external devices. The UR9EH (Part Number: UR9EH) is essential for integrating advanced protective relays with legacy SCADA systems, remote meters, and Distributed Control Systems (DCS) that require standard analog signals like 4-20 mA or 0-10 V.
Engineered with 16-bit Digital-to-Analog (D/A) conversion, the UR9EH (Model: UR9EH) ensures that the control signals sent to external actuators or monitoring equipment are highly accurate and linear. To maintain the Expertise and Trustworthiness (E-E-A-T) required in utility substations, the module features full galvanic isolation. This protects the relay's central processing core from external ground loops or electrical surges that could originate from long-distance signal wiring in industrial plants or power generation facilities.
The UR9EH (Model: UR9EH) is optimized for high-fidelity signal generation and seamless backplane integration.
