PRODUCT INFORMATION
Product Overview
The General Electric 469-P5-HI-A20-T-H is a Multilin Motor Management Relay for medium and large industrial motors. It provides integrated management and comprehensive protective elements. The relay accepts 5 A phase CT secondaries for precise current sensing. Its high control power supply operates across wide alternating and direct voltage ranges. The internal circuit assemblies feature conformal coating for harsh chemical protection.
The unit includes four 4 to 20 mA assignable analog outputs. Dedicated communication facilities feature a front RS-232 port, two rear RS-485 ports, and a 10Base-T Ethernet port. The Ethernet connection communicates using Modbus RTU over TCP/IP protocol. Users configure protective trips and monitoring parameters through EnerVista 469 Setup software. The physical drawout design allows straightforward maintenance and case extraction.
