The OMDC-MD Plus Series DC motor
controller is a field-programmable closed
loop DC drive system employing an
advanced velocity-form PID algorithm
for accurate and responsive control. The
OMDC-MD Plus control system also features
a unique, isolated 4 to 20 mA input and
output for easy integration with existing
process control systems. The OMDC-MD
Plus Series DC motor control is ideally
suited for metering pump applications by
efficiently combining all of the application

Ordering Examples: OMDC-MD40P-420, digital closed loop speed control for max 1 HP motor with max 5 Arm Amp, and OMDC-PU-40E,
shaft mounted pick-up sensor with 40 pulses per revolution, $715 + 114 = $829.
OMDC-MD50P-420, digital closed loop speed control for max 2 HP motor with max 10 Arm Amp, and OMDC-PU-40E, shaft mounted pick-up
sensor with 40 pulses per revolution, $835 + 114 = $949.

requirements into a single compact
package. The OMDC-MD Plus Series DC
motor control system not only accepts a
4 to 20 mA signal to control the pump
speed, but it also provides a 4 to 20 mA
output signal back to the process control
that is proportional to the actual running
speed. Both the input and output signals are
isolated from each other and from the
control itself. The OMDC-MD Plus control
also has two field-programmable form C
relay contacts that can be set to indicate a
wide variety of conditions such as the pump
is running, a “fault” condition exists, and
many other events.
