About the 469-P1-HI-A1-E-H
Able to function as a standalone unit or integrated into an existing system, General Electric Multilin’s 469-P1-HI-A1-E-H is intended for the management and protection of medium to large motors. The 469 is a Motor Management Relay with a number of adaptive capabilities that assist it in preserving motor life and reducing troubleshooting times, such as torque protection and dual overload curves.
In regard to communication functions, the 469-P1-HI-A1-E-H has an RS232 port at the front of the relay and two RS485 ports at the back of the relay. Both ports can wire direct connections to a computer running the EnerVista 469 software program. The EnerVista program allows easier setpoint editing, data viewing, and data trending. The EnerVista software can also export this data for analysis.
This version of the part comes with a conformal coating, a thin, polymeric protective film that deters corrosion, dust, humidity, and extreme temperatures. The conformal coating increases the durability of the relay and makes it safer for harsh operating environments. Conformal coating can be added to other relays in the series as well, as AX Control can apply it in house.
The 469 is encased in a standard SR 469 series chassis, consisting of a drawout unit and a dust-deterring door. The relay is fixed into the case through a number of pins, and installation is relatively simple when following the advice provided by the manufacturer in the 1601-0122-AG instruction manual.
