Gateway Basics: What to Look For

A basic intelligent gateway serves as a bridge between field devices (like sensors, PLCs, or controllers) and higher-level networks or cloud infrastructure. Main features typically include:

• Protocol conversion (e.g. Modbus TCP <-> RTU, MQTT, HTTP, OPC-UA)
• Data aggregation and local processing (some with edge compute capability)
• Secure connectivity options (wired and/or wireless)

Key Selection Criteria for Basic Intelligent Gateways

• Physical Interfaces: Confirm the required port type (RS232, RS485, Ethernet, USB, etc.) for your application.
• Protocols Supported: Ensure compatibility with your upstream/downstream systems (Modbus, MQTT, BACnet, etc.).
• Enclosure & Mounting: Choose between DIN-rail, panel-mount, or enclosure-ready units - especially for SA panel-building standards.
• Power Supply: Verify DC or AC input, voltage range (commonly 9-36VDC), and include an appropriate adapter if needed.
• Temperature Range: For field deployments, check that the gateway matches your site's expected environmental conditions.

Getting the Right Bundle - Compatible Accessories

• Matched power supply (with correct connector and voltage)
• Mounting hardware (DIN-rail clips, enclosure boxes)
• Patch cables, serial adapters, and sensor breakout boards
• Surge protection and cable glands for rugged installs
