Specifications
Control
Signal
Refer to the tables for actuator models and control types.
Power Inputs
See table.
Connections
3 ft (91 cm) appliance (see * in table below)
or 10 ft. (3 m) plenum cables, enclosure
accepts 1/2” (13 mm) conduit connector.
Electrical
Outputs
Position Feedback Voltage (proportional or floating only): For
voltage ranges, the feedback signal is the same range as
the input signal. The 4…20 mA current range and floating
actuators have a 2…10 Vdc feedback signal. The feedback
signal can supply up to 0.5 mA to operate up to four additional
slave actuators.
Mechanical
Outputs
Travel: 93° nominal.
Manual Override: Allows positioning of damper or valve using
manual crank.
RA/DA Jumper: Permits reverse acting/direct acting control
(MS4D models only).
Features
• Two position models controlled by SPST controller
• Floating models controlled by SPDT floating controllers
• Jumper selectable control function direct/reverse action
• Spring return models provide 30 in-lb (3.4 N-m) of torque
• Polymer housing rated for NEMA 2/IP54
• Overload protection throughout stroke
• Floating and proportional models automatically adjust input span to match the
damper/valve travel
• Compact size allows installation in limited space
• Manual override allows positioning of dampers and valves
• Directly mounts to 1/2…3” Schneider Electric ball valves
• Polymer housing rated for plenum use
