Eight digital inputs and nine digital outputs, plus two current sensing inputs, provide rich local I/O for protection and monitoring without external IO modules. This reduces panel footprint, simplifies wiring, and shortens commissioning time, delivering measurable savings in field labor. In transformer protection applications, the built-in I/O handles status indication, interlock signals, and alarm relays directly at the device. Modbus RTU or DNP3 RTU over RS-485 enables straightforward integration with SCADA, PI System, or energy management software. Business impact: centralized monitoring and data logging without bespoke interfaces, which lowers integration risk and accelerates downtime analysis. Application: OEM and industrial plants requiring reliable remote diagnostics across distributed protection relays. Wide power supply range of 19-300 Vdc and 40-250 Vac with 50/60 Hz support simplifies field wiring and reduces the need for multiple power rails. Impact: fewer transformers and power supplies, lower installation costs, and easier compliance with diverse plant power architectures. Application: system transformers and substations in manufacturing environments where supply conditions vary. Conformal coated circuit boards and removable terminals improve field reliability in harsh environments and simplify maintenance. Impact: improved PCB protection against moisture, dust, and humidity, plus faster terminal rework in the event of upgrades. Application: outdoor or dirty environments and retrofit projects where uptime matters. I/O options such as Sensitive Ground Input, IRIG-B time reference, URTD interface, and Trip Coil Monitor support advanced protection schemes and time synchronization. Impact: higher protection accuracy and easier integration with control systems. Application: zone selective interlocking and protection coordination in critical transformer installations. Warranty and support: One-year warranty from installation or 18 months from shipment; ensures a supplier-backed maintenance window.
