Industrial Serial Device Server | 4 Ports RS232/485/422 to Ethernet Converter, TCP/IP to serial, Dual Ethernet Ports
$98.99
💡 3-in-1 Interfaces & Dual LAN Cascading
The 4CH-RS232/485/422-ETH offers four ultra flexible serial ports, each can be independently wired as RS232, RS485 or RS422. Built-in dual 10/100M Ethernet ports can also be used as a network switch, allowing you to daisy-chain multiple devices without the need for an external switch.
Product Overview
The Valtoris 4CH-RS232/485/422-ETH is a high density, versatile industrial IoT gateway. It is designed to significantly reduce cabinet footprint and will easily upgrade up to four legacy serial instruments to a modern TCP/IP network. It is the ultimate data acquisition node for distributed control systems, with an autonomous Modbus RTU to TCP bridge, multi-host polling arbitration and native MQTT integration.
Quick Specs & Capabilities
- Hardware Interfaces: Four independent serial ports (RS232/485/422 selectable) and two RJ45 Ethernet ports with built-in cascading capabilities.
- Edge IoT Protocols: Intelligent Modbus RTU to Modbus TCP protocol conversion and automated MQTT/JSON payload parsing for direct cloud dashboarding.
- Multi-Host Concurrent Polling: Advanced bus arbitration prevents RS485 data collisions, allowing multiple SCADA servers or HMIs to access the same serial device simultaneously.
- Network Modes: Each of the 4 serial ports can be independently configured for TCP Server, TCP Client, UDP, or UDP Multicast.
- Power Input: DC 9~24V wide voltage operation, supporting both industrial screw terminals and a DC 5.5mm jack.
