EVDR4 Five-Valve Driver, Universal Input (EVDR4)
The EVDR4 valve driver provides precise, repeatable control of four proportional solenoid valve coils and one on/off solenoid valve coil. PWM input signals can be from a joystick, a PLC or Engine Control Module. Analog inputs and multiple switched inputs are optional to suit a range of applications. An onboard RS-232 port is used for user-configuration and diagnostics via PC.This versatile, multi-function controller is suitable for a wide range of heavy duty industrial, marine, and mobile off-highway equipment applications, such as transmission controls, vehicle traction controls, and drive-by-wire control systems.
