The SPINx1 is a one channel isolated digital potentiometer intended for spindle control. The SPINx1 takes three TTL level signals, PWM, DIR and ENA and has four isolated outputs: CW, CCW, ENA and VOUT. VOUT is a Analog voltage proportional to the PWM input signal and the Analog reference voltage (5 to 18VDC). The SPINX1 outputs 0 to 100 percent of the supplied voltage, its a potentiometer replacement. Input voltage must be from 5 to 15V.
