Function

Four PROFIBUS PA segments are transparently coupled to the PROFIBUS DP V1 network to support seamless integration of devices and data transmission.

Optional redundancy configuration is provided to ensure high system availability and support multi-master architecture.

Built-in diagnostic function, monitoring section status, faults and loads through LED indicator lights and integrated tools.

Supports adaptive transmission rate (9.6 kbps...) 12 Mbps), compatible with the Power Hub system, and easy to expand.

Equipped with a SUB-D9 interface, it is convenient to connect to the control system and is suitable for hot-swapping maintenance.

Application scenarios

HD2-GTR-4PA is widely used in process industries such as petrochemicals, pharmaceuticals, oil refining and mining, and is suitable for explosive hazard areas in Zone 2 or Class I, Div. 2. It is used to connect multiple PROFIBUS PA field devices (such as sensors and actuators) to the DP network, achieving real-time process control and diagnosis, and supporting Industry 4.0 applications. The equipment complies with ATEX, IECEx and cULus certifications, and is suitable for automation systems that require high reliability and redundancy, such as fieldbus infrastructure in large process plants.
