Sure Grip SDB-P1 Single Axis Driver Boards Details

These Sure Grip Driver Boards proportionally drive 2 solenoids. Suitable for Joysticks, Slider Modules or Variable Voltage Modules.  

Accepting a single input 0.5 - 2.5 - 4.5VDC from Electronic Joysticks, the output of a Slider Module or controlled by separate inputs of 0.8 - 4.2VDC, such as 2 Variable Voltage Modules.

Sure Grip SDB-P1 Single Axis Driver Boards are available with multiple attachment options.


The Sure Grip Single Axis Driver Board is designed to proportionally drive two solenoids using proportional control devices such as Joysticks, Slider Modules, or Variable Voltage Modules.

With the Sure Grip SDB-P1 driver board it can be configured to accept a single proportional input in the range of 0.5 - 2.5 - 4.5VDC, such as one axis output from a Joystick or the output of a proportional Slider Module. And can be controlled by two separate proportional inputs in the range of 0.8 - 4.2VDC, such as two Variable Voltage Modules.

These Sure Grip Driver Boards have two proportional high current PWM outputs and one switched "auxiliary" output that turns on when either of the PWM outputs are activated. This "auxiliary" function is often used to divert hydraulic oil to an auxiliary valve for a machine attachment. Current compensation is provided on both PWM outputs to accomodate for changes in solenoid coil resistance due to temperature variations.

All the outputs feature protection against inductive kick back and are short circuit protected. If any of the outputs are shorted to ground, the board will automatically shut down to help protect itself against any damage until the problem is corrected.

Optional Features

The Sure Grip Single Axis Driver Board can be supplied with an external switch (shown below) that is used to select between three different sets of adjustable operating parameters that can be used to control up to three different machine attachments. When an attachment is changed, the operator can simply move the switch to the position corresponding to the new attachment and restart the machine to activate the new flow settings.

This feature allows the control of up to three attachments using the same valve. The operating parameters for each of the three attachment profiles are set up using the on-board calibration interface, in addition to load calibration and PWM output frequency adjustments. Without the external switch option, the calibration interface allows the user to configure a single set of operating parameters.
