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-confi guration 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.
• Microprocessor based control (standard software or OEM software on request).• Standard hardware and software adapts to many applications including interface to a joystick PWM command or proportional signals.• Independent outputs for four proportional valves (0…2A) and 1on/off valve (< 2 A).• Interfaces to up to 2 PWM signal inputs (interface to a 2 axis joystick).• Up to four voltage or current analog inputs: 0-5V, 0-10V, 4-20 mA or 0-20 mA.• Digital inputs for interface to switches, etc., (up to 6).• Robust 8…36VDC power supply interface with reverse polarity protection.• One, +5V reference voltage to power input devices.• Thermal overload and overvoltage protection provided.• Rugged IP67-rated packaging with IP69K-rated plug-in connections.• Operational from -40 to 85°C (-40 to 185°F).• RS232 interface to PC or laptop for user confi guration and diagnostics.
