Single axis driver board - 0-5V analog/digital input to 2 x PWM outputs in 3 modes. Data sheet The Single Axis Driver Board is designed to proportionally drive two solenoids using proportional control devices such as Joysticks, Slider Modules. The SDB-P1 driver board 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. It can also be configured to be controlled by two separate proportional inputs in the range of 0.8 - 4.2VDC.
