FAQs

Plan for semi-flush mounting and removable terminals to simplify wiring. Ensure the 8-input, 9-output I/O fits your protection scheme, and verify the unit is powered from 19-300 VDC or 40-250 VAC with 50/60 Hz. Allocate space for RS-485 and Ethernet network connections, and consider the URTD, Trip Coil Monitor, and IRIG-B options when wiring for trip logic and timing.
Key specs include 8 digital inputs, 9 digital outputs, 2 current sensing inputs, and protection functions such as Current Protection, Metering, and Differential Protection. Power supply range covers 19-300 VDC and 40-250 VAC, with 50/60 Hz frequency. Communication is via RS-485 Modbus RTU and Ethernet RJ-45, enabling remote monitoring and integration with SCADA.
Yes. The unit is designed as a transformer protection relay with multi-functional protection and monitoring capabilities, including zone interlocking and differential protection. Its 8/9 IO, remote communication options, and time-sync features support OEM and industrial installations that require reliable protection coordination and diagnostics across distributed transformer assets.
Compliances field indicates to contact the manufacturer for definitive certifications. In practice, transformer protection relays commonly address CE considerations for European markets, SIL safety reliability practices, and enclosure IP ratings that suit the installation environment.
