Product Overview
The Schneider Electric ACE949-2 is a high-performance 2-wire RS485 interface card specifically engineered to bridge SEPAM protection relays with supervisory control and data acquisition (SCADA) systems. This module acts as a critical communication gateway, allowing for the remote monitoring and management of electrical protection parameters within a power distribution network. Designed for high dielectric strength and signal stability, the ACE949-2 ensures that protection data is transmitted accurately even in environments characterized by extreme electromagnetic interference. Its specialized 2-wire architecture simplifies field wiring while providing the robust connectivity required for modern substation automation and industrial power management.
