APPLICATION:
The EC0004A conveniently interfaces a PLC or transducer with a proportional solenoid.
DESCRIPTION:
The EC0004A has been designed to meet the various requirements of mobile and industrial
hydraulic control applications. EC0004A cards 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 EC0004A can accept any of the following
input types: Potentiometer, 0-1OV, 0-5V, or 4-20mA. The card 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.
