PR-2709 Relay for Dover Elevator Controllers, DPDT 120V AC Coil

This heavy-duty control relay is commonly found in Dover elevator controllers where dependable switching performance is required. It is frequently identified in the field by the legacy part numbers 71922, PR2709 (PR-2709), and PR2709-6 (PR-2709-6), making it a practical replacement option for maintenance, modernization, and inventory stocking applications.

Designed as an open-style power relay with a double-pole double-throw (DPDT) contact arrangement, this relay is suitable for elevator control circuits requiring high-current switching capability and reliable mechanical operation. Because multiple controller revisions and field modifications may exist, buyers should carefully verify coil voltage, contact configuration, terminal arrangement, and electrical ratings before ordering to ensure compatibility with their specific equipment. The legacy part numbers listed above are provided as identification references only and may have been used across different applications.
