Multilin GE 469-P5-HI-A20-E Motor Management Relay

Description

The Multilin GE 469-P5-HI-A20-E Motor Management Relay is a high-reliability, multi-functional device designed for industrial motor control and protection applications. As part of the SR 469 relay series, it integrates comprehensive monitoring, protection, and communication capabilities to safeguard and manage motors effectively. Key protective functions include real-time monitoring of motor current, voltage, and temperature parameters, with automatic power cutoff during faults such as overload, short circuit, phase loss, and overheating. It supports multiple RTD inputs for precise motor temperature tracking to prevent overheating risks.

Technical specifications include a control power range of 90-300 VDC or 70-265 VAC, operating frequency of 48-62 Hz, and rated current options of 1A or 5A CT secondary. It offers selectable protection ratings of IP20 or IP54, with an optional harsh-environment conformal coating for enhanced chemical resistance. The relay features four 4-20 mA analog outputs for seamless integration with PLC or DCS systems, plus rich communication interfaces including RS232, RS485, Ethernet, and support for DeviceNet, Modbus RTU, and Modbus TCP/IP protocols. Its user-friendly front panel includes a large LCD display, programmable RS232 port (9600 baud, upgradable to 19200 baud), and sealed drawer handle to prevent unauthorized access. Dimensions measure 200 mm x 168 mm, with a weight of approximately 2.2 kg.
