FLINT WDG85
Compact wireless IoT gateway — RS485 Modbus RTU, 4G LTE, GPS sync, and 5-year onboard storage in a DIN-rail package.
Everything you need to bridge the industrial edge.
Six built-in capabilities — no extra hardware, no middleware, no compromises.
Easy Integration
Connect PLCs, SCADA, sensors and energy meters through standard RS485 and RS232 interfaces — no additional middleware required.
Multiple Interfaces
RS232 and RS485 Modbus RTU ensure plug-and-play compatibility with virtually any external industrial device or sensor in the field.
4G LTE Communication
Quad-Band GSM/LTE modem pushes data to any web server or cloud platform from wherever there is cellular coverage — no local network needed.
Dual Analog Inputs
2 analog inputs (0–10 V / 4–20 mA), 1 digital output, and serial ports give comprehensive signal coverage in a single compact unit.
5-Year SD Storage
8 GB micro SD card logs over five years of data in .csv format. Expandable to 32 GB — data survives every network outage.
GPS Time Sync
Synchronises on every network connection via GPS and server time, ensuring precise timestamps across all logged parameters.

Built for the field. Ready for any industry.
From factory automation to remote water systems — FLINT WDG85 connects it all over 4G LTE.
Process Automation
Connect your factory floor to the cloud. Bridge RS485 PLCs, SCADA, and control systems to live dashboards — without replacing existing infrastructure or running new cabling.
Industrial IoT
Turn legacy equipment into smart assets. 4G LTE eliminates the need for factory Wi-Fi or Ethernet runs. Any machine with an RS485 port becomes instantly cloud-connected.
Remote Utilities
Monitor remote sites, anywhere. Send readings from remote installations over cellular, and store years of data locally for compliance reporting.
Cold Chain
Zero tolerance for temperature excursions. Continuous temperature and humidity logging with SMS alerts. SD card backup ensures no data loss during connectivity outages.
Built-in connectivity, right out of the box.
