The MGC447 and MGC547 generator panels provide inexpensive engine and generator monitoring and control with digital accuracy. These
These panels accept a variety of sensor inputs such as from Murphy electric gage type resis- tive sending units and digital inputs such as from SWICHGAGE® instruments.
The MGC447 and MGC547 feature open col- lector transistor type and relay type outputs. These compact panels measure only
The user is able to start or stop the engine, view operating parameters and reset or acknowledge abnormal conditions from a computer.
