The Si24DiBdMC1-50V-20A-AP1 is a 50V 20A, microprocessor based, high-power, Digital, Bidirectional, Motor Controller that uses a single power supply to control the speed of a DC motor in forward or reverse direction at a voltage-range of 9V to 50V and with a current-range of 0 to 20A. An onboard microprocessor generates a 5kHz or 20kHz PWM carrier signal, controls the load-power (or motor speed), controls the load-current rate (or motor acceleration and deceleration), updates the Liquid Crystal Display (LCD) and monitors the user inputs. The PWM carrier frequency is user selectable by the jumper CN7, 20kHz when CN7 is open and 5kHz when short. The user can choose between slow or fast motor acceleration/deceleration modes by short-circuiting or open-circuiting the pins labeled J1. As the name digital (Di) implies, the required motor speed (or PWM pulse-duration) is adjusted in 0.83% steps with Up/Down RPM push-buttons (connected to port CN6) while the motor direction is selected using two active low digital (0 to 5V) control signals or switches. A bicolor LED is used to monitor the motor (or load) voltage (Red = Forward, Green = Reverse). An LCD port (with HITACHI HD44780 Interface Standard and with back-light) is provided for optional display of motor RPM data in a 2 line by 20 character format. A small(3.3”x4.0”x0.065”) AP1 Aluminum plate is required to operate at 20A current levels.
