PVD3D2E

Product catalog summary

Overview: The PVD3D2E is a proportional valve driver with two PWM solenoid outputs, designed by PWM Controls Inc. It features a versatile digital design with easy-to-use adjustments and a three-digit LED display. The device is energy-efficient, requiring no heat sink, and is protected against wrong connections and short circuits.

Specifications: The driver operates on a voltage range of 9-35VDC with a maximum output current of 3A. It supports ramp times from 0.0 to 99.5 seconds and maintains a linearity of 0.5%. The PWM/dither frequency ranges from 50-500Hz, and it operates in temperatures from -40° to +75° Celsius. It complies with EMC Directive 2004/108/EC standards.

Input and Output: The device accepts user-selectable input signals of 0-5V, 0-10V, 0-20mA, or 4-20mA. It can control either one dual solenoid valve or two independent single valves, with settings for high and low output currents, ramp up/down times, and deadband percentages.

Setup Procedure: Users can modify settings by rotating controls to adjust values, which take effect immediately except for input range selections that require saving. The setup mode allows sequential adjustment of various parameters, and settings can be saved or discarded by powering down without saving.

Wiring Diagrams: The document includes wiring diagrams for dual mode (one dual solenoid valve) and single mode (two independent solenoids) configurations, with signals from analogue cards/PLCs or potentiometers/joysticks.

Functional Diagrams: Functional diagrams illustrate the dual mode for one dual solenoid valve and single mode for two independent solenoids.
