Some industrial applications like speed control need an input in the range 0-10V and 2 binaries input for the direction of the motion.
The usual solution is to connect together the 2 terminals of the potentiometer to the +10V, then the center tap to the 0V.
The direction detection is made by 2 switches. All joysticks do not have this possibility, particularly those without center tap or the ones with Hall effect sensors.
Otherwise all joysticks do not have direction switches.
Developed and manufactured by ANDIG, MJA-448 offers to any joystick an +10V_0_+10V output and two NPN outputs (open collector) per axis.
The wide range power supply covers most of the requirements.
It can also convert the output of an analog sensor to a special function curve (ie a special speedup function)
