Honeywell ML6161A2025 , Inc. 35 lb-in Non-Spring Return Direct Coupled Damper Actuator

"DCA

Honeywell "DCA" actuators are designed for control of air flow in combustion systems where precise, reliable motor position feedback is required. The actuator employs a chip absolute position encoder which is used to obtain feedback on motor position by converting the chip codes into count or digital signals. The drive circuitry will compare these signals with nominal setpoint values to determine if actuation or hold conditions have been met and will energize the motor drive accordingly. This device has a logic controlled, non-spring return direct coupled damper actuator with a potentiometer as its feedback mechanism.

Spend less time worrying about your damper and more time enjoying the fireplace.  Our powerful DCA is the perfect solution for direct-coupled fireplace dampers, providing full force and ease of operation at the touch of a finger. The system's non-spring return feature makes it convenient to use with any style of fireplace - especially gas-fired fireplaces where a spring return can cause problems."

A DCA Premium Non-Spring Return Direct Coupled Damper Actuator is most commonly used for damper applications that need to obtain accurate flow control and precise position control. Using a non-spring return design, which eliminates overshoot, this actuator is used for large volume air handling, where the total amount of damping force required may exceed 25 lb-in for a given application.

LONGBRANCH, CT November 25, 2014 – Honeywell Process Solutions has launched the DCA3160 Direct Coupled Actuator for HVAC and Indoor Air Quality (IAQ) markets. DCA3160 is a non-spring return direct coupled actuator that is controlled by Honeywell's proven variable frequency drive technology. It features auto-tuning of the position of the control knob positions to enable easy installation and zero errors during commissioning of Damper Control Applications (DCA).

The Honeywell ML6161A2025 DCA has a core size of 1-3/8 in. (32 mm) and a plate thickness of 0.47 in. (12.1 mm). It is suitable for use as either a secondary or primary damper actuator, and is available with built-in end switches so that it will reset when the damper is returned to the start position."

Exceptional for use between forced air furnaces and hydronic heating systems, our non-spring return, direct coupled DCA is designed to allow the damper to open in response to temperature rise. When used with our line of DSD actuators, it allows a flow path to be opened or closed under thermostatic control. Our DCA also has a built-in thermistor that senses when the damper port temperature reaches a certain level, which can be used as an automatic control input on some heating controls.

The Honeywell ML6161A2025 DCA is a non-spring return DC actuator and damper to implement heating and cooling solutions in residential or light commercial applications.
