All kinds with RS485 port device parameter settings , data communication
Short distance , such as parameter settings of the computer peripheral equipment , the use of common data lines can be .
A and A port of the device when the wiring is connected , B and device B connected . Some devices D + A and D, – B .
The Device is a mnolithic integrated high voltage,high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors.
To simplify use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are includ
L9110, The ASIC device control and drive motor design two-channel push-pull power amplifier discrete circuits integrated into a monolithic IC, peripheral devices and reduce the cost, improve the reliability of the whole.
This is essentially a ramped up version of our Ardumoto motor driver shield. For this monster shield we’ve replaced the L298 H-bridge with a pair of VNH2SP30 full-bridge motor drivers. We’ve also beefed up the support circuitry so this board The VIN and motor out are pitched for our 5mm screw terminals (not included), making it easy to connect larger gauge wires.
This is mini pwm control speed and light dimmer controller .This is suitable for DC light dimmers motor speed control. Adjust the potentiometer knob to change the governor output duty cycle, the motor speed changes.
