Industrial RS485 to Ethernet Converters & IoT Gateways

The DeviceLab DL-RS485 is an industrial-grade RS485-to-Ethernet serial device server engineered specifically for harsh, high-electromagnetic-interference (EMI) environments. It features 3.0kV galvanic optical isolation, 600W TVS surge protection, dual hardware/software watchdog timers for 24/7 anti-freeze reliability, and full support for Modbus Gateway (Modbus RTU to Modbus TCP), TCP Server/Client, UDP, and Virtual COM modes.

• ✓ 3.0kVAC Galvanic Isolation eliminates ground loops, paired with 600W TVS surge suppression
• ✓ Dual Watchdog mechanism (Hardware + Software) provides automatic 24/7 fault recovery without manual intervention
• ✓ Versatile communication modes: Modbus RTU ↔ Modbus TCP Gateway, TCP Server/Client, UDP & Virtual COM

The DeviceLab DL-IOT-GW is an industrial edge IoT gateway engineered to autonomously poll Modbus RS485 field instruments and publish telemetry directly to Cloud/On-Premise platforms via MQTT, HTTP REST API, or Modbus TCP. It features high-speed Multi-Master Caching (< 2ms) to eliminate bus contention, intuitive web-based RS485 bus diagnostics, 100,000-record Store & Forward offline buffering, and optional PoE power.

• ✓ Modbus Multi-Master Caching (< 2ms) eliminates serial bus contention when SCADA, Cloud, and HMI poll simultaneously
• ✓ Automatic Modbus register-to-JSON serialization pushed directly to MQTT Brokers (TLS 1.2/1.3 encrypted)
• ✓ Built-in Web RS485 Bus Diagnostics: scans online Slave IDs, measures CRC error rates, detects polarity reversals

The DeviceLab DL-IOT-GW-4 is an enterprise-grade industrial multi-port edge computing gateway featuring 4 fully galvanically isolated RS485 ports and dual Gigabit Ethernet ports. Designed for main switchboards (MSB), large-scale building management systems (BMS), and automated smart factories, it aggregates up to 128 field Modbus devices across 4 independent serial branches on a unified Linux edge hardware platform.

• ✓ 4 Fully independent galvanically isolated RS485 channels (3.0kV per port), aggregating up to 128 devices
• ✓ Dual independent Gigabit RJ45 ports (Dual Subnet) securely separating factory OT networks from corporate IT/Cloud
• ✓ Powerful Edge Computing architecture: Quad-Core 1.5 GHz, 1GB RAM, 8GB eMMC running Industrial Linux, Node-RED, Python
