Certificate #02.002.1
Sealed Interface Control: EC20300
FEATURES:
• 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
start.
• 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.
APPLICATION:
The EC20300 conveniently interfaces a PLC or transducer with a proportional solenoid.
DESCRIPTION:
The EC20300 has been designed to meet the various requirements of mobile and industrial
hydraulic control applications. EC20300 controls are versatile, cost effective and easily
integrated into new or pre-existing designs. Much of this is a result of the unique ability
each card has to accept 4 different signals. The EC20300 can accept any of the following
input types: Potentiometer, 0-10V, 0-5V, or 4-20mA. The control takes these signals and
converts them into a PWM output suitable for a Brand EFC-Series valve or other
proportional valves that meet the proper specifications.
