CAN Valve Driver

✓ Off the Shelf System

The CAN Valve Driver is a small potted module that's commonly used to drive proportional valves from an electronic joystick or potentiometers, or J1939 sources. It has two analog inputs to read signals from a joystick, potentiometers, or other control devices, and has two current-regulated proportional outputs to drive most proportional valves. It has configurable input to output mapping, adjustable min/max/ramp/frequency for each output, and min/max/center for the inputs. Programming can be done from an on-board set of trimpots and jumpers, or more easily using our WiFi programming interface. Another common use is as a "soft-start" card - it will take a switch input and can just simply ramp up a proportional output to prevent mechanical shock. In this configuration, the analog inputs are configured for 0–5v, normally to be interfaced with a pressure transducer, inclinometer, or similar.

With the addition of J1939, the CAN valve driver is a massively flexible hydraulic valve controller, or can be used to bring inputs into your CANbus network. Inputs can be fed back to J1939, and all all parameters of the inputs and outputs are under your control.
