16 digital inputs and 9 digital outputs enable flexible signaling and direct interlocks for generator protection. The business impact is simplified wiring, faster fault isolation, and reduced panel complexity. Application-wise, these I/O capabilities support start/stop logic, alarm signaling, and safety interlocks in industrial genset rooms and remote sites. Two current sensing inputs provide accurate protection curves and metering. The business impact is improved protection reliability and clearer load visibility, minimizing nuisance trips and unplanned downtime. In practice, users apply differential protection, motor protection-style logic, and metering functions to guard generators in data centers and manufacturing lines. Modbus RTU or DNP3 RTU communications over RS-485 enable seamless SCADA integration. The business impact is centralized monitoring, remote diagnostics, and reduced field wiring, which accelerate maintenance planning. Applications include plant-wide generator control rooms, remote windings, and UPS extensions, where fast fault signaling matters. A wide power supply range of 19-300 Vdc and 40-250 Vac makes this relay compatible with diverse genset configurations. The business impact is deployment flexibility, easier OEM integration, and fewer rework cycles when generator sets are upgraded or replaced. This is particularly valuable for multi-vendor campuses and modular power installations. Conformal coated circuit boards, removable terminals, and IRIG-B timing support enhance reliability in harsh environments. The business impact is improved weather resistance, straightforward field servicing, and precise time synchronization for event logging. Applications span outdoor generator enclosures, industrial facilities, and mission-critical plants requiring accurate timing. Zone selective interlocking and comprehensive sensing options—differential, voltage, current, and power protection with metering—provide coordinated protection. The business impact is selective tripping, reduced arc-flash exposure, and faster fault localization. In practice, this delivers a robust protection architecture for generators synchronized with switchgear and MCCs in manufacturing and data-center infrastructures.

FAQs
Begin by confirming RS-485 compatibility with Modbus RTU or DNP3 RTU on your control network. Mount the unit on a semi-flush panel, connect the 16 digital inputs and 9 digital outputs to your start/stop, alarm, and interlock circuits, and wire the two current-sensing inputs for protection logic. Use the removable base for field servicing and ensure power supply connections cover the 19-300 Vdc / 40-250 Vac range. Validate timing with IRIG-B if synchronization is required.
Key specs include power supply range of 19-300 Vdc and 40-250 Vac, 50/60 Hz operation, 16 digital inputs, 9 digital outputs, and 2 current-sensing inputs. Protection coverage includes differential protection, voltage protection and metering, current protection and metering, and power protection and metering. Communications support Modbus RTU or DNP3 RTU over RS-485 for remote monitoring and control.
Yes, it is suitable for data center standby gensets where reliable protection, clear metering, and SCADA integration are required. Its RS-485 communications enable centralized monitoring, while the 16 DI / 9 DO I/O set supports essential interlocks, alarms, and start/stop control. Ensure timing and protocol compatibility with your data center management system for optimal results.
