489-P5-LO-A1-E

About the 489-P5-LO-A1-E

The 489-P5-LO-A1-E Generator Management Relay featured here was of course first manufactured by Multilin, an offshoot of General Electric, for insertion in the fitting 489 Generator Management Series assembly. This 489-P5-LO-A1-E is powered through the help of a series of critical voltage and diagnostic ranges, which include but aren't limited to its:

• 20-60VDC/20-48VAC Control Power Ratings
• 5A-rated CT Inputs
• 0-1 mA Analog Outputs

The normative activity of the 489-P5-LO-A1-E Generator Management Relay, as well as its hardware components' adherence to these described ratings is indicated through a total of 22 light-emitting diagnostic diodes on its front interface.

Critical 489-P5-LO-A1-E Hardware

The selection of over twenty LED indicators in this 489-P5-LO-A1-E Generator Management Relay's assembly are of course not its only hardware components of note. For starters, the internal mechanisms of the 489-P5-LO-A1-E Relay are all stored inside a heavy-duty metallic chassis with a number of holes factory-punctured in its to still allow for standard natural air circulation. Some other great 489-P5-LO-A1-E Generator Management Relay hardware elements are its: 

• 6 total Output Relays
• 10 Analog Inputs
• RS232 Serial Port

In addition to this 489-P5-LO-A1-E Generator Management Relay's sole RS232 serial port, it also seems to make use of two rear-mounted RS485 female ports available on the back of the unit for further connectivity.
