Catalog excerpts

• Weather tight control package • Pulse Width Modulated output • Waterproof altitude pressure and vapor release vent allows enclosure to "breathe". • Protected against reverse polarity, short circuit, and over voltage conditions. • Current controlled output, maintains output current regardless of supply voltage and coil resistance variations. • On board proportional indicators for input signal and output signal. Also includes an on/off power and potentiometer status indicator. • Two Enable lines are provided, one with adjustable soft stop, both with adjustable soft • Independent ramp adjustments up and down, 0.1 -12 seconds. • Minimum and Maximum current adjustment for fine tuning the outputs span. • Wide voltage supply range 12-30 VDC, one control for 12 or 24VDC systems. Proportionally control the speed of hydraulic motors and cylinders. Easy to use and versatile the EC20200 simplifies valve control and system design. It is built with high quality long life components that are designed for use in harsh environments. The EC20200 is a perfect compliment to the Brand EFC and LEFC flow controls. Other flow controls meeting the appropriate specifications may be used as well.
