Function

Provide 28... for a single FOUNDATION Fieldbus H1 or PROFIBUS PA segment A stable isolated power supply of 30 V DC and 500 mA, supporting the concept of high-power trunk lines, suitable for long cable and multi-device scenarios.

Integrated short-circuit and surge protection, automatically limiting current to ensure the segment continues to operate in the event of a fault.

It is equipped with LED indicator lights to show power supply and fault status, facilitating on-site diagnosis and maintenance.

High-efficiency design (≥ 95%), low heat dissipation, suitable for installation in high-density cabinets, and supports hot-swapping maintenance.

Compatible with the FieldConnex Power Hub system, it supports redundant configuration and provides advanced diagnostic functions.

Application scenarios

HCD2-FBPS-1.500 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 provides reliable power for field bus segments (such as sensors and actuators), ensuring stable communication between field devices and control systems (such as DCS or PLC), and supports IIoT and Industry 4.0 applications. The equipment complies with ATEX, IECEx and cULus certifications and is suitable for automation systems that require highly reliable power supplies and explosion protection, such as fieldbus infrastructure in large process plants.
