2-Ch RS485 to POE Ethernet Converter Industrial Isolated Serial Server, 2-Ch RS485 Independent Operation, Dual POE Eth Ports, Modbus Gateway MQTT Gateway JSON Support, Rail-mount Metal Case

• Support Ethernet Port Cascade, onboard 2-ch Ethernet Ports for communication and cascade, either one can be used for dual serial server network communication, while the other one can be used for cascading or communication with other devices
• Support screw terminal and DC power port for power supply or PoE port, DC 6~45V, wide voltage range input
• Modbus gateway support, suitable for Modbus networking upgrade, can be used with specific configuration software. Supports TCP server / TCP client / UDP multicast / UDP mode. MQTT/JSON to Modbus, more flexible conversion between different protocols
• Multi hosts roll-polling support. User-defined heartbeat/registration packet. NTP protocol support. Multi configuration methods
• Multiple protection, safe and stable, onboard power supply and signal isolation, built-in TVS and resettable fuse and protection diode etc. Rail-mount support, industrial-grade rail design, compact size, easy installation, cost-effective
