Introduction

Minarik’s DLC500 control is used with variable speed drives to
produce closed-loop digital systems capable of controlling motor
speed precisely and with excellent reproducibility. The DLC500
includes these benefits:

Excellent speed regulation: 0.05% speed regulation of set speed
for tight control.

Pushbutton programming: Quick and easy programming using
three front panel pushbuttons.

4-digit LED display: 0.5 inch (13 mm) wide digits are easily
readable.

Programmable decimal point: Great for specific application
readouts.

Selectable feedback devices: Controls accept magnetic pickup,
hall effect, inductive proximity sensor or encoder input.

+5 VDC or +12 VDC (10 mA) power supply for feedback
devices: Additional power supply is unnecessary.

Removable screw-terminal block: Easy terminal block
connections.
