Servo Valve Driver

✓ Off the Shelf System

The Servo Valve Driver is a small potted module that is commonly used to drive low current servo valves from an electronic joystick or potentiometers sources. It has two analog inputs to read signals from a joystick, potentiometers, or other control devices, and has two current-regulated proportional outputs supplying up to 1000 milliamps each for driving most servo 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.
