Isolated RS-485 to Wi-Fi Bridge with 24 VAC Power Reference Design
Description
TIDA-00486 uses our 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. The 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 avaialble in TIDA-00485.
Features
- Wide-input voltage range of 18-V to 30-V AC and 12-V to 48-V DCFly-Buck power supply delivers 3.3 V at 550 mA and isolated 3.6 V at 50 mAAdd Wi-Fi connectivity to an RS-485 network quickly and simplyGalvanically isolated RS-485 interface to improve system safety and reliabilityCC3200 application processor provides adaptability to customer communication protocols
