For example, the relay can measure a high-voltage primary current through its CT inputs and then use the UR5CH to output a proportional 4-20mA signal to a legacy SCADA RTU or a local panel meter.\u003c\/p\u003e\n\u003cp\u003eFurthermore, the module includes comprehensive self-diagnostics. If a transducer wire is broken (Open Circuit) or shorted, the UR5CH detects the out-of-range signal and can trigger a \"Module Not OK\" alarm. This prevents the control system from making decisions based on \"frozen\" or erroneous data, a common failure mode in traditional analog systems.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eTechnical FAQs\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: Can I mix voltage and current inputs on the same UR5CH module?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA1: This depends on the specific ordering code of your UR5CH module. Some versions are \"Current Only\" or \"Voltage Only,\" while others are hardware-configured at the factory for a specific mix. Check the module's side label for the specific channel mapping.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: How do I calibrate a channel if the reading is slightly off?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA2: The UR5CH is factory-calibrated. However, you can apply a \"User Offset\" and \"Gain\" through the EnerVista software to compensate for resistance losses in long field cable runs, ensuring the value displayed on the relay HMI matches the physical measurement at the sensor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Is the UR5CH suitable for high-speed protection trips?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA3: Transducer signals generally have an update rate of approximately 100ms. While excellent for monitoring and slow-acting control (like cooling fans or tap changers), they are not intended for high-speed \"Instantaneous\" electrical protection, which should be handled by the relay's CT\/VT modules.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: What happens to the outputs if the relay loses power?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA4: Upon loss of power, the D\/A converters will de-energize, and the d-c output signals will drop to zero. Ensure your downstream control logic (in the PLC or DCS) is programmed to recognize a 0mA signal as a \"Fail-Safe\" or \"Loss of Signal\" condition.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":52695424237931,"sku":"UR-5CH","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/general-electric-ur5ch-transducer-i-o-module-i1nqcieht53_7fc2aed4-e6e7-4bb8-b23a-a005cb0eca91.jpg?v=1766135514","url":"https:\/\/www.plcprotech.com\/products\/ge-ur5ch-multilin-ur-transducer-i-o-module-universal-relay-series","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
