Electronic actuator drive is used to provide proportional
control of an electric gear train actuator from a variable
milliamp DC signal from a controller.
Features
Range: Factory set at 4 to 20 mAdc. Field adjustable to
accept ranges such as 2 thru 7, 2 thru 12, 7 thru 12, 4 thru
12, 12 thru 20 mAdc.
Span: Factory set at 16 mAdc. Field adjustable 4 to 16
mAdc.
Start Point: Factory set at 4 mAdc. Field adjustable from
2 to 16 mAdc.
Impedance: 250 ohms for constant current output
controllers. Other impedances can be obtained by adding
series or parallel resistors for controllers without a
constant current output.
Grounding: Either or both input wires grounded will not
cause damage.
Maximum: 40 mAdc.
Isolation: Optically.
Series Operation: A common controller connected in
series with two actuator drives will control each drive
independently of the other.
Hysteresis: Factory set for 3 to 5% of 16 mA span.
Hysteresis is the difference between the input signal which
will rotate the actuator shaft one way and the level which will
drive it the other way.
Linerity: 0.15% of actuator rotation.
Power Requirements: 120 or 240 Vac, +10%, with fixed
input signal offset of +1% maximum. 24 Vac units not
available.
Power Consumption: 3.5 VA at 120 or 240 Vac, 50 or 60
Hz.
Ambient Temperature Limits: -13 to 140° F(-25 to 60°C).
Connections: Color coded pigtail leads.
Case: Aluminum.
Mounting: Directly to actuator. Upright position preferred,
but other positions are acceptable.
Dimensions: 4-5/8" high x 4-1/16" wide x 2-1/2" deep (117
mm x 103 mm x 63 mm).
