Product Overview

The IntelliGway HMG-2 bridges legacy HART instruments with modern industrial communication networks.

It converts HART communication into Modbus RTU and Modbus TCP while preserving existing 4–20 mA infrastructure.

Supports up to two isolated HART channels operating in both point-to-point and multi-drop modes.

Built-in loop resistors simplify installation and reduce wiring complexity.
