Industrial Isolated 4 Ports RS485 to Ethernet Server, 4 Channels RS485 independent operation, Rail-mount Metal Case, Dual Ethernet Ports
Price range: $69.99 through $79.99
💡 Dual LAN Cascading & Power Options
4CH-RS485-ETH-V has 2 10/100M Ethernet ports with built-in switch function, so that multiple devices can be cascaded without external switch. Note: Model (V) is for DC 9~24V, Model (VI) is for DC 18~36V.
Product Overview
The Valtoris 4CH-RS485-ETH-V is enterprise level 4 channel RS485 to Ethernet serial server. The device is designed for centralized facility automation and provides bi-directional transparent data transmission over four independent serial channels. It offers native Modbus gateway support and advanced multi-host polling, providing a solid networking upgrade for legacy control panels.
Quick Specs & Capabilities
- Hardware Interfaces: Four independent RS485 ports and dual 10/100M RJ45 Ethernet ports with built-in network switching (cascading support).
- Multi-Mode Operation: Each channel can be configured separately for TCP Server, TCP Client, UDP, or UDP Multicast modes.
- Edge IoT Protocols: Seamless Modbus RTU to Modbus TCP conversion for immediate SCADA network upgrades. Includes automated MQTT and JSON data routing logic.
- Multi-Host Stability: Advanced bus arbitration ensures stable concurrent polling from multiple host systems.
- Installation Flexibility: Compact enclosure supporting both DIN-Rail and Wall-Mount installations.
