Industrial RS485 Converters
Modbus RTU to TCP gateways for the factory floor. Wired, wireless, and cellular — backed by a 2-year warranty and free technical support.

RS485 to Ethernet Converter
Industrial Modbus RTU → TCP gateway over 10 Mbps Ethernet.
- Modbus RTU ⇄ Modbus TCP bridging
- Wide operating temperature (-40 to 75 °C)
- 10 Mbps Ethernet (RJ45)
- Dual power input (6–24 VDC)
- Surge & ESD protection

RS485 to WiFi Converter
Wireless gateway with native MQTT for cloud platforms.
- WiFi (802.11 a/b/g/n) + Ethernet
- Native MQTT — AWS, Azure, ThingConnect
- Modbus RTU ⇄ TCP bridging
- Wide operating temperature (-40 to 75 °C)
- Multi-client TCP — multiple SCADAs
Side by side
Wired or wireless?
Both share the same industrial enclosure, RS485 protection, and warranty. The wireless variant adds WiFi and MQTT for cloud-bound deployments.
