Product Description
Industrial-grade protocol converter that bridges up to 4 independent RS-485 serial buses to Ethernet (TCP/IP). Powered via PoE (IEEE 802.3af), eliminating the need for a separate power supply.
Supports Modbus RTU to Modbus TCP transparent conversion, making it ideal for connecting legacy serial instruments, PLCs, sensors, and actuators to modern IP networks.
Key features:
• 4 independent RS-485 channels with individual baud rate settings
• PoE powered — single cable for data and power
• DIN-rail mountable for panel installations
• Web-based configuration interface
• Supports up to 32 Modbus devices per channel
• Baud rates from 300 to 921600 bps
