Description
The differential Pulse Train Output (PTO) module TI Design illustrates the design of a differential high speed digital output module using RS-485 driver powered from the PLC backplane using isolated Fly-Buck power converter. The reference design is mainly used in positioning and motion control systems to allow simple distant high speed motor control in noisy environments.
Features
- 4 high speed differential digital output channels
- 1 MHz pulse frequency
- 25 mA maximum load current per channel for 100Ω load
- 750 mW total power consumption from backplane isolated power stage (150 mA)
- Parallel control for simple MCU interface
- Beaglebone Black cape form factor for easy evaluation using TIDEP0027
