Description
The APD 3280 controls the position of a valve or linear actuator
by comparing a DC input (control signal) to that of a position
feedback potentiometer or slidewire.
load
An SPDT relay provides bi-directional (open-close) signals to
drive a motor to open or close a valve. A bi-color LED indicates
the Open/Close relay contact status.
When the valve position, as indicated by the feedback poten-
tiometer, becomes equal to the position as represented by the
control input, the relay will go to the neutral position and the
motor will halt. A multi-turn deadband control allows precise
tuning of the motor response to eliminate hunting or oscillation.
Heavy-duty relay contacts allow the module to directly control
high capacity loads as long as the switching current with within
the limits shown at left.
How to Order
Models are field rangeable. Switches can pre-set to your
specifications. See range table on other side.
Any full range feedback potentiometer or slidewire from
0-100 Ω to 0-100 kΩ can be used, no need to specify range.
Order APD 3280 D for operation on low voltage power.

Auto/Manual Switch
An Auto/Manual switch allows either closed-loop automatic
valve 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.
LoopTracker
A green LoopTracker LED varies in intensity with changes in
the control input signal. Monitoring this LED can provide a
quick visual picture of your process at all times and save time
during initial startup and/or troubleshooting.
