Description

The TIDA-00486 TI Design uses Texas Instruments SimpleLink Wi-Fi CC3200 Internet-on-a-chip Wireless MCU module to create a data bridge between an RS-485 network and a Wi-Fi network. An ISO15 transceiver provides an isolated RS-485 interface with up to 2500 VRMS of isolation. The LM5160 Fly-Buck™ power supply provides both isolated and non-isolated 3.3 V outputs for the two portions of the circuit. The design can be powered with AC or DC power up to 30 VRMS or 48 V peak

A version of this design with a non-isolated RS-485 interface is presented in TIDA-00485.

Features
  • Wide Input Voltage Range of 18 V to 30 V AC,  12 V to 48 V DC
  • Fly-Buck™ Power Supply delivers 3.3 V at 550 mA, Isolated 3.6 V at 50 mA
  • Add Wi-Fi® connectivity to an RS-485 network quickly and simply
  • Galvanically isolated RS-485 interface to improve system safety and reliability
  • CC3200 Application Processor Provides Adaptability to Customer Communication Protocols
