ACCEPTS 4-20 mA OR 0-10 VDC input signals from PLC’s, Transducers, etc. (Input
signal must be specified when ordering (4-20 mA is standard at this time))
LIGHTWEIGHT IN DESIGN to minimize panel fatigue.
SMALL IN SIZE to minimize space requirements.
PULSE WIDTH MODULATION OUTPUT to reduce the effects of hysteresis.
SHORT CIRCUIT PROTECTION to guard against over current conditions. (Onboard Fuse)
INPUT PROTECTION from voltage transients, load dumps and reverse polarity from supply
voltage.
PLUGGABLE TERMINAL BLOCKS for easy wiring.
CAN BE MOUNTED to a 35mm DIN rail, Series rail or surface mounted.
CAN BE PACKAGED for mobile applications.
LED’S TO INDICATE that power is present and to indicate that an input signal is present.
COATED CIRCUIT BOARD has a special conformal coating to guard against moisture,
dust and other contaminates.

Electronic Interface Control
EC-GENERAL INFORMATION:
The Brand, electronic interface control is designed to proportionally adjust the Brand EFC-Series
valves and other proportional valves that meet the appropriate solenoid specifications. The control
can be mounted on a standard DIN rail or Series rail. Brand can also package these controls for
harsh environment use on mobile equipment.
This control will take the industry standard 4-20 mA or 0-10 VDC signal and convert it to a linear
Pulse Width Modulated (PWM) output. This signal may be found in many devices, for example,
Programmable Logic Controllers (PLC’s), pressure sensors, flow sensors, ultrasonic sensors,
position sensors and AC current sensors, just to name a few.
Each controller produced is burned-in for 24 hours after assembly to assure the controller is
operating properly and meets all specifications. There are also many other quality assurance
procedures that our controllers go through before they are shipped. All tests are performed with
up to date, state of the art test equipment that is calibrated to NIST standards by an independent
laboratory on a yearly basis.
