FAQs
Install the device using standard mounting and removable terminals for quick field retrofit. Connect 8 digital inputs and 6 digital outputs as required for your feeder protection scheme, and supply power within the 19-300 VDC / 40-250 VAC range. Follow the manufacturer’s installation guide for wiring color codes, RS485 termination, and proper torque on terminal screws to ensure reliable operation in harsh industrial environments.
Yes. The relay supports Modbus RTU and DNP3.0 RTU over RS485, enabling straightforward integration with SCADA and automation systems. This dual-protocol capability simplifies data collection, status monitoring, and coordinated protection across multiple feeders and distributed assets.
The unit accepts 19-300 VDC or 40-250 VAC and operates across a wide temperature range from -20°C to 60°C. This makes it suitable for factory floors, outdoor enclosures, and spaces with temperature variation, while maintaining reliable protection and signaling.
Ideal for feeder protection in electrical distribution panels, substations, data centers, and large manufacturing facilities. It consolidates protection and control I/O, supports remote monitoring via RS485 communications, and provides reliable fault isolation to minimize downtime in critical energy and process systems.
By integrating protection and control in a single device with RS485 communications, it reduces external I/O modules and wiring complexity, shortening commissioning and maintenance cycles. The 5 A contact rating, 10 W / 17 VA burden, and wide power range contribute to lower operational costs, while remote monitoring capabilities support predictive maintenance and faster fault diagnosis.
