Applications
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.
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.
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.
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
