Description
The Schneider Electric ACE949-2 2-Wire RS485 Network Interface is designed to enable seamless communication between Sepam Series 20 protection relays and supervisory control systems. This network interface facilitates Modbus RTU communication over an RS485 2-wire protocol, offering reliable data exchange for standard distribution system applications. With a compact and rugged design, the ACE949-2 is ideal for use in industrial environments, ensuring stable and secure communication for protection, monitoring, and control of electrical distribution systems.

The Sepam Series 20 protection relay provides 7 types of digital current or voltage protection specifically tailored to meet the requirements of standard distribution systems. Each protection function is dedicated to a specific application, ensuring optimal protection for transformers, circuit breakers, and other critical equipment. The relay is equipped with a communication interface supporting 2-wire RS485 Modbus protocol, making it easy to integrate with SCADA or other control systems for remote monitoring and management.

This protection relay operates with a 12 VDC or 24 VDC power supply and has a low current consumption of 16 mA in receiving mode and 40 mA in sending mode, making it energy-efficient for continuous operation. Its compact dimensions (88 mm height, 72 mm width, 30 mm depth) allow for easy mounting on a DIN rail, simplifying installation and maintenance in electrical panels.With its robust design and high reliability, the ACE949-2 and Sepam Series 20 combination ensures comprehensive protection, monitoring, and communication capabilities for electrical distribution systems in industrial and commercial applications.
