Eight digital inputs, two current-sensing inputs, and nine outputs provide a versatile I/O backbone for the unit. This dense I/O reduces external wiring, shortens installation time, and accelerates fault detection, improving protection reliability for transformers in substations or OEM equipment. Wide power supply range of 19-300 Vdc and 40-250 Vac at 50/60 Hz supports mixed voltage environments, reducing inventory and wiring complexity while enabling seamless integration with existing plant power. Removable terminals and semi-flush mounting simplify field servicing and retrofits, cutting downtime during maintenance or upgrades. Profibus-DP over fiber optic ST delivers robust, noise-immune communication for PLCs and SCADA systems in harsh environments, enabling reliable control and monitoring across the network. IO options such as Trip Coil Monitor, IRIG‑B, and URTD Interface extend diagnostics and time synchronization, supporting precise protection coordination in complex plants. Sensing inputs include Voltage Protection and Metering, Differential Protection, Current Protection and Metering, and Power Protection and Metering, delivering broad protection coverage with accurate metering for asset management. Zone Selective Interlocking supports two zones to improve selectivity and minimize outage impact in feeder protection schemes. Conformal coating on circuit boards enhances reliability in harsh environments, making the unit suitable for outdoor enclosures and rugged installations. The combination of these features reduces risk, improves reliability, and supports compliant protection strategies in modern transformer protection architectures.

FAQs

Begin by mounting the unit in a semi-flush position with the removable terminals accessible. Connect the 8 digital inputs, 2 current-sensing inputs, and 9 outputs according to your protection scheme, then power the device from 19-300 Vdc or 40-250 Vac. Verify Profibus-DP over fiber optic ST link to your PLC, and calibrate protection thresholds using the manufacturer's spec sheet.
The fiber optic channel provides noise-immune, secure communication for high‑speed data exchange with PLCs and SCADA systems, reducing communication errors in industrial environments. This enables reliable monitoring, remote trip commands, and coordinative protection strategies across transformer assets.
Yes. The relay supports a wide power supply range of 19-300 Vdc and 40-250 Vac at 50/60 Hz, allowing it to operate within mixed electrical environments without requiring multiple power supplies or extra adapters. This simplifies installation and reduces spare parts requirements.
The unit offers Voltage Protection and Metering, Differential Protection, Current Protection and Metering, and Power Protection and Metering. Combined with zone selective interlocking and time-synchronization options, it delivers comprehensive transformer protection and precise fault localization across complex power networks.
Consider the removable terminals for easier field servicing, conformal coating for rugged environments, and the extensive I/O and networking options that reduce external hardware. These features lower maintenance time and improve uptime, contributing to a favorable total cost of ownership through reduced diagnostics, faster fault isolation, and longer asset life.
