These Honeywell M7284 Q 1009/U servos are a modern and reliable solution designed to replace multiple engine models and ensure stable operation in various operating conditions. The devices have a built-in return spring for safety and a built-in junction box for environmental protection.

They operate from a voltage of 24 VAC and have quick-release terminals for easy installation, and adapter brackets are also provided to adapt to old engines.

Location

When choosing a location, leave enough space for installing accessories and servicing the engine. When installing outdoors, use moisture-proof connectors and a junction box that provides protection from external conditions of NEMA 3 class. When installed outdoors in any position other than vertical, use the 4074ERU environmental protection kit and NEMA 3 waterproof connectors.
