Additional Specifications

Power Options 120 Vac, single-phase, 50 or 60 Hz, 1.5A
240 Vac, single-phase, 50 or 60 Hz, 0.75A
Operating Conditions –40° to 85° C. (–40° to 185° F.) 0 to 99% relative humidity
Communications Interface HART© protocol and local pushbutton/LED panel and RS-232 serial commands
Demand Input Signal
4–20 mA, 1–5 V dc
Minimum Step 0.1° of span
Hysteresis 0.25% of span at any point
Demand Input Signal
Linear: Drive output shaft moves
proportionally to the input signal.
Square: Drive output shaft moves
proportionally to the square of the input
Custom: 20 segment configurable curve fit
Position Feedback Signal 4–20 mA
Isolation Demand input and position Feedback signals are isolated from ground and the ac power line. Signal buffering provides 24 V dc isolation between the Demand and Feedback signals.
Action on Loss of Power Output shaft stays in last position
Action on Loss of Input Signal (Power on) Stay in place or runs to any preset position (configurable)
Over-thrust Protection If the output thrust of the drive exceeds 150% of the drive rating, the motor will shut off (feature can be enabled / disabled).
Stall Protection If the motor tries to run in one direction for more than 300 seconds (configurable from 30 to 300 seconds), the motor will shut off.
Over-travel Protection Switches Two Form C (Retract and Extend) provide over-travel protection
Auxiliary Switches
(Field Adjustable)
Two Form C, rated for 1 A, 250 V ac
Handswitch Permits local electrical operation, independent of Demand input signal.
Handwheel Provides manual operation without electrical power.
Motor 120 Vac, single-phase, no burnout, noncoasting. Capable of 60 starts per minute
Enclosure Precision-machined aluminum alloy castings, painted with corrosion-resistant polyurethane paint, to provide a rugged, dust-tight, weatherproof enclosure designed to meet NEMA 4X standards.
Mounting Orientation Can be mounted in any orientation
