Texas Instruments

Analog Input: Output and Relay Drive Output Module for Smart Grid IEDs Reference Design

Description

This reference design showcases a flexible Analog IO solution for Smart Grid devices like Protection Relays and RTUs that also need to communicate with other devices on the grid that use the analog IO such as voltage (5V to 10V DC) or current (4-20mA). This solution enables both types of IO as well as a power digital relay drive. SPI and I2C communication interfaces are available on this module for communication to the processor.

Features
  • Analog I/O handled includes:Current Input 0-20mA / 0-24mA / 4-20mA DCVoltage Input 0-5V DC / 0-10V DCExcellent accuracy High Sampling rate (up to 500kSPS) Simplifies connectivity to MCU with SPI interfaceAnalog Output handling includes:Flexible solution – configurableCurrent/Voltage outputsDAC Daisy Chaining minimizes connectivity to MCUDigital Output handling includes:4x better power efficiency with respect to ULN series
