VR9034B - Loss of excitation and consequently loss of synchronism or the appropriate polar angle may jeopardize the integrity of the system and the machine. This relay monitors the machine's field voltage by detecting an abnormal decrease in it, signaling a fault if the abnormal detection persists for the selected time.

• Protection against loss of excitation by voltage monitoring method.
• Condition and fault indication by front LEDs.
• “Enable” and “Reset” signal inputs by dry contacts (10 mA/12 VDC optically coupled).
• “Test” and “Reset” buttons on the front.
• 110 VAC or 220 VAC power supply
• All selections on front digital switches (DIP Switches).
