Terminal Unit (RTU, DTU, FTU, TTU)

Distribution Automation - Terminal Unit

Description

A terminal unit is a device used for intelligent remote monitoring and control of various devices and systems by interfacing the physical assets at substations to distributed control systems or SCADA (supervisory control and data acquisition) systems. Transformer Terminal unit (TTU) monitors the state of the transformer in a distribution automation system. Similarly Distribution Terminal unit (DTU) and Feeder Terminal unit (TTU) monitors the status of the feeders typically connected in a ring topology at the secondary distribution level. TI reference designs and ICs help:

  • Showcase Analog to digital converters (ADC), digital to analog converters (DAC) and operational amplifiers ideal for accurate measurement of voltage, current and temperature
  • Cover various methods for transmitting telemetry data to a master system through interfaces such as RS232, RS485 , 10/100-bast T Ethernet
  • Support multiple industrial protocols on the same hardware, adding redundancy (HSR/PRP) through PRU-ICSS sub system for communicating real-time between a Master Terminal Unit (MTU) other Terminal Units for sending data, supervisory and control signals
