Eaton distribution relay EDR-3000-2C1EA0 - Profibus-DP

Wide power-supply range and flexible I/O scope enable universal deployment across machines and panels, reducing the need for multiple adapters and cutting spare-part inventory. The business impact is lower capital expenditure and faster project timelines, with straightforward integration into feeder protection schemes for manufacturing lines. In practice, engineers apply the 19-300 Vdc / 40-250 Vac range to support both local DC bus and AC supplies in diverse machines, improving reliability and uptime in control cabinets. The Profibus-DP over D-Sub / RS485 interface delivers reliable fieldbus communication, enabling PLCs and SCADA systems to monitor protection states and switchgear health in real time. This reduces commissioning time and improves fault visibility, translating to safer, more efficient plant operation. For data-driven maintenance, current protection and metering capabilities feed accurate energy metrics into asset management platforms, supporting predictive maintenance and energy optimization. Zone selective interlocking (ZSI) further confines fault zones, shortening interruption durations and reducing wear on upstream devices. The module’s I/O options, including IRIG-B and Sensitive Ground Input, support precise timing and grounding strategies in complex automation architectures. Removable terminals and semi-flush mounting simplify wiring and cabinet integration, while the 4 inputs / 4 outputs layout offers clear, scalable control topology. In short, this relay blends robust protection with practical installation advantages, helping engineers meet stringent uptime targets.
