| 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
Range |
4–20 mA, 1–5 V dc |
| Minimum Step |
0.1° of span |
| Hysteresis |
0.25% of span at any point |
Demand Input Signal
Characterization |
Linear: Drive output shaft moves
proportionally to the input signal.
Square: Drive output shaft moves
proportionally to the square of the input
signal.
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 |
