Eagle Eye - Model VGM-100 - Battery Ground Fault & Voltage Dual Monitor

When the VGM-100 is installed & power is applied to the battery ground fault monitor, the firmware reads the stored settings and begins monitoring. Changing the stored settings, including the over and under voltage parameters & the ground fault conditions are easily done on the monitor's color touchscreen. If over or under voltage is detected, the voltage status will appear and the VGM-100 can activate a Form C contact. If a ground fault is detected, a positive or negative ground fault monitoring message will appear on the color touchscreen, and the VGM-100 will also activate another alarm contact. Modbus protocol output is also available on all units.

The unit is equipped with a total of four (4) Form C Output Contacts for alarm conditions - (1) for Under Voltage, (1) for Over Voltage, (1) for Positive Ground Fault Conditions, and (1) for Negative Ground Fault Conditions. The VGM-100 is extremely durable and easily installed as a wall, panel, or DIN rail unit.

Battery voltage monitoring will provide critical battery cell protection and ensure the longevity of the battery system. Over voltage can lead to overcharging and overheating of the batteries, which can cause irreversible cell destruction. Under voltage will also cause irreversible battery damage if left uncorrected. Measuring battery voltage with the VGM-100 will allow the user to determine how charged their batteries are, and allow for immediate corrective action if needed. Battery ground faults can be difficult to locate and may create catastrophic and costly damage if they remain undetected. The entire battery system will be compromised and subject itself to overheating, thermal runaway, and reduced battery capacity. Continuous ground fault and battery voltage monitoring will eliminate those risks, and allow for immediate corrective action to happen if a ground fault is located.
