Input Power
120 V ac, single-phase
50 or 60 Hz
Control Types
Modulating with Digital Control Module (DCM)
Modulating direct AC motor control with CPS or Film Potentiometer
2 position (open/close) control
Input and Feedback Signals
4-20 mA (1-5 Vdc input is possible with Option 9 actuators)
Available Communication Protocols
Option 9 actuators may be equipped with HART or Fieldbus Foundation technology
Minimum Step Size (Modulating Control)
DCM — 0.10% (0.15% typical)(configurable)
Direct AC — 0.1° (function of control system capabilities)
Isolation
Demand Input and Position Feedback signals are isolated from the ground and the ac power line.
Operating Conditions
-20° to 85° C. (-4° to 185° F.) – Standard
-20° to 120° C. (-4° to 248° F.) – Optional (High Temperature)
-50° to 85° C. (-58° to 185° F.) – Optional (Low Temperature)
Mounting Orientation
Any orientation – no limitations
Action on Loss of Power
Stays in place.
Action on Loss of Input Signal
(Power On)
Stays in place or, on some drives, is field configurable to move to any preset position.
Overtravel Limit Switches (Dedicated)
Two form C switches provide overtravel protection (option 9) or end-of-travel limits (Option 6, 5, 3).
Auxiliary Switches (non-dedicated)
Up to four 3 A, 120 V ac switches available. Switches are cam-operated and field-adjustable.
Handswitch
Permits local electrical operation, independent of controller signal. Standard on all units. An optional auxiliary contact can be used to indicate that the Handswitch is in “AUTO” mode or to sound an alarm if it is taken out of “AUTO”.
Handwheel
Provides manual operation without electrical power.
Mechanical Stops
Prevent overtravel during automatic or manual operation.
Stall Protection
On DCM equipped units, protects actuator and driven elements under stall conditions. Time to stall is configurable from 30 to 300 seconds.
Enclosure
Precision-machined, aluminum alloy castings painted with corrosion-resistant polyurethane paint provide a rugged, dust-tight weatherproof enclosure. Designed to meet Type 4X and IP68 (3 meters/48 hours).
