The Honeywell A47-2MEG is a compact, programmable digital overcurrent relay designed to provide precision protection for medium-voltage electrical systems. It features advanced technologies like adaptive pickup, high speed communications for setpoint signals, communication latency filtering, and built-in IEC 61850-3 process bus capability. The A47-2MEG offers optimally tuned protection curves, adjustable trip and reset points, and selectable tripping times for improved system performance. With its high speed communication port, it supports multiple protocol communications with peer relays and substation automation systems, and supports UPnP, Modbus, and OPC protocols for third party integration. The device also has built-in IEC 61850 compliance for communications. The A47-2MEG can be digitally controlled, configured, and monitored over multiple communication protocols. It is ideal for medium-voltage applications, including circuit breakers, transformers, motors, and generators.
