1U Rack-Mount 16-Port Serial Device Server, Industrial RS232/485/422 to RJ45 Ethernet Converter with 4 LAN Ports, Optional POE
Price range: $329.00 through $349.00
💡 1U Rack-Mount, AC 220V & RJ45 Serial Ports
The 16CH-RS232/485/422-ETH is designed for standard 19-inch server racks (1U height) and operates directly on AC 220V power. Note that in high density wiring all 16 serial interfaces use RJ45 physical connectors (configurable for RS232, RS485 or RS422).
Product Overview
The Valtoris 16CH-RS232/485/422-ETH is an enterprise-class, high-capacity 16-Port Serial Device Server. Built for large-scale data aggregation in central control rooms, it seamlessly bridges massive arrays of field instruments to your backbone network. The powerful ARM9 processor, integrated 4-port network switch, autonomous Modbus RTU/TCP conversion and multi-host polling provide the highest throughput and stability for complex SCADA telemetry.
Quick Specs & Capabilities
- High-Density Interfaces: 16 independent serial ports (RS232/485/422 selectable) and an integrated 4-port 10/100M Ethernet switch for easy cascading.
- Edge IoT & Modbus: Fully supports Modbus RTU to Modbus TCP gateway functions and automated MQTT/JSON edge computing logic.
- Full-Duplex Performance: Ensures all 16 channels can operate simultaneously at continuous high baud rates (up to 921.6Kbps) without packet loss.
- Multi-Host Arbitration: Advanced data buffering allows multiple master stations to poll the same serial device network concurrently without bus conflicts.
- Form Factor & Power: Standard 19-inch 1U rack-mount chassis (480mm × 180mm × 44mm) equipped with a direct AC 220V power input.
Please confirm the model number you need before purchasing:
If need RS232/RS485, please choose option 1
If need RS232/RS485/RS422, please choose option 2
Note: If an RS422 interface version is required, then the RS232 flow control bit will not be available.
