These Honeywell M7284Q1098/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.


When choosing a location for installing the Honeywell M7284Q 1098/B servomotors, it is recommended to provide sufficient space to accommodate the necessary accessories and ensure the convenience of engine maintenance. In the case of outdoor installation, it is necessary to use moisture-proof connectors and a junction box with protection from external conditions conforming to the NEMA 3 standard.

For outdoor installation in any position, except vertical, it is recommended to use the 4074ERU environmental protection kit together with moisture-proof connectors corresponding to the NEMA 3 protection class. This will provide reliable protection against external influences, such as moisture and dust, and improve the overall performance and durability of installed servomotors.
