TIDA-00766 Reference Design

Texas Instruments

Differential Pulse Train Output (PTO) Programmable Logic Controller (PLC) Module Reference Design


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.
