The EC20300 Sealed Interface Control 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.
