5950 – Micro Proportional Driver


5950 - micro proportional driver

A Micro Proportional Driver provides accurate control of hydraulic and pneumatic proportional solenoid valves used in mobile construction equipment and industrial processes. The MPD can control the flow of air or liquid linearly at a setting from 0.10-20 seconds. One example of use would be in a paint system. The MPD allows a solenoid to oscillate, significantly reducing system shock and wear commonly found in non-oscillation digital valve systems. The micro proportional driver is a compact electronic circuit built into an environment-resistant miniaturized enclosure. the circuit features control of proportional solenoids and operators. Functions include minimum and maximum current limiting, control signals from 0-10V or 0-20 mA (with a step function at 0.2V or 0.4 mA included for minimum current), a 0.1-20 sec. linear ramp up/ramp down adjustment and output current proportional to input command signal. This unit incorporates the DIN 43650 Form “A” / ISO 4400, EN175301-803:2000 connector male and female interface. The unit is mounted by use of a single mounting screw, DIN connector and two gaskets. Built to meet NEMA 4 environment standards, the MPD is made from engineered polymers for resistance to harsh chemicals and ingress of water or foreign substances. adjustments are made on the top surface of the unit. the unit can control any proportional solenoid valve operation within the values specified below using variable pulse width modulation.
