Why Choose a 1-Port RS485 to Ethernet Converter?

• Network-enable single RS485 nodes quickly without rewiring.
• Ideal for Modbus RTU/ASCII integration with SCADA, BMS, and bespoke automation.
• Works as a transparent bridge or with configuration for tunneling, TCP server/client, or UDP modes.
• Compact, DIN-rail or panel mountable options for industrial environments.

Features to Compare

For most South African deployments, look for models rated for wide voltage input (e.g., 9-36V DC), robust surge protection, and easy configuration via browser, Windows utility, or serial console. Always check compatibility with your PLC/SCADA software, and confirm stock at Samrand or regional branches for urgent jobs.

How to Select the Right Converter

• Serial Interface: Verify RS485 pinout (2-wire or 4-wire), and if dual-standard (RS232/RS422) support is needed.
• Network Environment: Ensure 10/100 Ethernet and compatible protocols (TCP server/client, UDP, Modbus Gateway).
• Installation: Choose DIN-rail, wall, or PCB-mount style to fit panel or field box.
• Input Power: Confirm voltage input range (12V or 24V DC common in SA industrial control).
• IP Addressing: Plan for static IP or DHCP setup; check web UI and documentation support.
• Device Management: Some converters support serial tunneling, virtual COM port drivers, or REST API for remote management.
