A bi-color LED indicatesthe Open/Close relay contact status.When the valve position, as indicated by the feedback poten-tiometer, becomes equal to the position as represented by thecontrol input, the relay will go to the neutral position and themotor will halt. A multi-turn deadband control allows precisetuning of the motor response to eliminate hunting or oscillation.Heavy-duty relay contacts allow the module to directly controlhigh capacity loads as long as the switching current with withinthe limits shown at left.Auto/Manual SwitchAn Auto/Manual switch allows either closed-loop automaticvalve position control or manual positioning via the Open/Close buttons.The manual mode is useful for troubleshooting, calibration,system testing or as a manual bypass.LoopTrackerA green LoopTracker LED varies in intensity with changes inthe control input signal. Monitoring this LED can provide aquick visual picture of your process at all times and save timeduring initial startup and/or troubleshooting.Models are field rangeable. Switches can pre-set to yourspecifications. See range table on other side.Any full range feedback potentiometer or slidewire from0-100 Ω to 0-100 kΩ can be used, no need to specify range.Order APD 3280 D for operation on low voltage power.Please SpecifyModelControl input range (if factory is to pre-set switches)Options as requiredHow to OrderRemovable PlugsDimensions0.89" W x 4.62" H x 4.81" D22.5 mm W x 117 mm H x 122 mm DHeight includes connectorsControl InputMinimum Span Maximum SpanVoltage: 0-50 mVDC 0-10 VDCCurrent: 0-1 mADC 0-20 mADC1 VDC maximum burden @ 20 mAControl Input ImpedanceVoltage: 250 kΩ min.Current: 50 Ω typicalCommon Mode Rejection100 dB minimumInput CalibrationMulti-turn zero and span potentiometers±10% of span adjustment range typicalLoop Power Supply15 VDC ±10%, 25 mA max. to power external loads such asloop powered transmitters, sensors, etc.Feedback Potentiometer RangeAny full range potentiometer 0-100 Ω to 0-100 kΩPotentiometer excitation: 1.0 VDC nominal, 10 mA maximumManual ControlsAutomatic/manual switchManual open and close buttonsLoopTrackerVariable brightness LEDs for input level and statusRelay OutputSPDT relay with neutral contact position8 A max @ 240 VAC resistive loadAn RC snubber is recommended for inductive loadsDeadband12 turn potentiometer adjustable from 1 to 25% of spanResponse Time100 milliseconds nominalIsolationPower to input isolationHousing and ConnectorsIP 40, requires installation in panel or enclosureFor use in Pollution Degree 2 EnvironmentMount vertically to a 35 mm DIN railFour 4-terminal removable connectors, 14 AWG max wire sizeAmbient Temperature Range and Stability–10°C to +60°C operating ambientBetter than ±0.02% of span per °C stabilityPower85-265 VAC, 50/60 Hz or 60-300 VDC, 2 W maximumD versions: 9-30 VDC or 10-32 VAC 50/60 Hz, 2 W maximumQ Valve Position ControllerQ Linear Actuator ControllerQ Damper ControllerModel Description PowerAPD 3280 Field configurable valvepositioner for potentiometeror slidewire feedback.8 A max.
