Resideo Braukmann ml6161b2024/u Damper Valve Actuator Floating Point on Off Non-spring Return 35 In-lb 24V Ac Nema 1

Product Description

The Resideo Braukmann ML6161B2024/U is a non-spring return actuator designed for use with dampers and valves in commercial and light industrial HVAC systems. This actuator delivers 35 in-lb of torque and operates on 24V AC power, making it compatible with a wide range of building automation and HVAC control systems. It supports both floating point and on/off control signals, giving HVAC technicians and controls installers the flexibility to integrate it into multiple system types without additional adapters or signal converters. Because it uses a non-spring return design, it has no fail-safe mechanism to move the damper or valve during a power outage. This trade-off results in a more compact form factor and simpler long-term maintenance compared to spring return actuators. It is best suited for non-critical damper and valve applications where fail-safe positioning is not required by code or system design. The actuator rotates 90 degrees in both clockwise and counterclockwise directions and completes a full stroke in 90 seconds. It mounts directly to the damper or valve shaft using a two-set-screw aluminum hub, providing a firm and stable connection during continuous cycling. Two built-in auxiliary switches with an SPDT contact form allow the actuator to send position feedback signals back to a building automation system or controller. Screw terminal electrical connections make field wiring straightforward and reliable. The unit carries a NEMA 1 rating, which means it is intended for use in indoor, dry locations. It measures 5.5 inches tall, 3.5 inches wide, and 2.5 inches deep, keeping its footprint minimal in tight mechanical rooms or air handling units. The power consumption is only 1.8 VA, reducing the load on 24V AC transformers. Operating temperature range spans from 20 degrees Fahrenheit to 125 degrees Fahrenheit, covering standard indoor HVAC environments. The 4074ENY bag assembly is included. Manufactured in Mexico.

• Supports floating point and on/off control signals for flexible integration into HVAC and building automation systems
