TAC DuraDrive Direct Coupled Actuators are
designed to be used in both damper and valve control
applications. The following general instructions are for
damper applications. Refer to the Applicable Literature
table for valve literature.
The MS4X-7XX3 series spring return actuators provide
proportional modulation control of dampers and valves
in HVAC systems.
Features- Proportional models controlled by 6-9 Vdc, 2-10
Vdc, or 4-20 mA with the addition of a 500 ohm
resistor
- Rugged die-case housings rated for NEMA 2 / IP54
- Optional built-in auxiliary switch to provide for
interfacing or signaling
- Provides 95° of rotation
- Visual position indicator provided
- Provides true mechanical clockwise or
counterclockwise spring return operation for reliable
fail safe application and positive close-off in air tight
damper applications
- MS40-7043-MPX models controlled by 6-9 Vdc with
auxiliary 20 Vdc power supply provides power to
controllers, replacing MP-5XXX/MPR-5XXX
electrohydraulic actuators
- Direct mount to round or square damper shafts
- Switch provided for selection of direct or reverse
acting control mode
- Rotation limiting available
- MS4X-7153 series actuators can be doublemounted
(gang mounting) to accommodate high
torque application requirements
- Five year warranty
