New Valve Driver ExDR-0201A

The ExDR-0201A is a dual output valve driver featuring SAE J1939 CAN communications. Flashing the firmware, changing operating parameters, and input/output monitoring are possible through CAN. The driver can operate independently or as a slave, responding to messages on the CAN network.

This unit drives two-coil proportional directional valves. It features separate metering profiles for A and B coils and independent input/output ramps with unique rates for rising and falling signals. Using the EFDR firmware personality you can also drive a proportional fan control with reversing valve.

Design Specifications

HydraForce continues to expand its line of electronic controls with two new economical, compact, digital valve drivers. Digital control of your valves means you can set the parameters for your application in the software and every driver will perform identically. There is no tuning or adjustment required to dial-in the driver as with older analog controls.
