Insulation Resistance Monitoring Device K7GE-MG Reliable, Safe and Accurate Automatic Insulation Resistance Measurements Measures insulation resistance automatically when a trigger signal is input Identifies the trend in insulation deterioration from the measurement data collected via communications Conducts measurements safely with a Megger voltage of 50 VDC Able to measure up to eight points simultaneously Constantly monitors the voltage applied to the device targeted for measurement, and automatically stops measurement if the target device power is turned ON after measurement has started Refer to your OMRON website for the most recent information on applicable safety standards. Overview The K7GE-MG is a device that automatically measures the insulation resistance of a load and supports trend monitoring. Periodic inspections by manpower may cause a unexpected machine stoppage due to a decrease in insulation resistance of equipment before the next inspection. The K7GE-MG provides automatic monitoring of the insulation resistance of each load and allows planned maintenance. The K7GE-MG measures the insulation resistance by the same detection principle (Megger method) as a Megohmmeter. To measure the insulation resistance using the K7GE-MG, it is necessary to combine one Main Unit with at least one Probe Unit. Main Unit Probe Unit (K7GE-MGM) (K7GE-MG1) The functions of the Main Unit and Probe Unit are shown in the figure on the right. The Main Unit correspond to a Megohmmeter, and the Probe Unit correspond to a measurement probe with internal contacts. The Main Unit turns ON these contacts in sequence and measure multiple loads individually. Up to eight Probe Units can be connected to one Main Unit.
