Design files

Overview

This high-speed digital output reference design for programmable logic controllers (PLCs) illustrates low-cost, simple high-speed single-ended digital output module using standard low-side driver and backplane powered using isolated power stage. High-speed digital output modules are required for motor control and positioning applications.

Features
  • Four high-speed digital outputs
  • External load power
  • Single-ended outputs working up to 500-kHz with 5-V field power and 100-kHz with 24-V filed power
  • 210-mW power consumption from backplane isolated power stage
  • Less than 100-ns transition time with 15-m cable
  • 300-mW power consumption per load for 5-V supply, and 44-Ω load

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
