Honeywell M6194B1011 Modutrol IV Non-Spring Return Motor Actuator 24V 300 lb-in

The Honeywell M6194B1011 is a Series 61 Modutrol IV non-spring return floating control motor designed for precise operation of dampers and valves in commercial HVAC applications. This foot-mounted actuator delivers 300 lb-in torque with reliable 24 VAC operation, making it ideal for controlling normally open or normally closed dampers and valves in systems requiring floating control.

Key Features:

• 24 VAC operation at 50/60 Hz with 17 VA power consumption
• 300 lb-in torque rating for reliable operation of large dampers and valves
• Field-adjustable stroke from 90 to 160 degrees for flexible installation
• 60-120 second nominal timing for smooth, controlled positioning
• One internal auxiliary switch for system status monitoring
• Dual shafts (slotted and tapped on both ends) for versatile mounting options
• Integral junction box provides NEMA 3 weather protection when mounted upright
• Quick-connect terminals standard for easy wiring
• Fixed torque throughout entire voltage range for consistent performance
• Non-spring return design maintains position during power interruption

This motor actuator works with controllers providing switched SPDT or floating output signals. The M6194B1011 replaces older M644E1012 motors and features integral auxiliary switch cams for precise position feedback. Built for durability and engineered for commercial building automation systems, this Modutrol IV motor delivers the precision control needed in demanding HVAC environments.
