Function

Provide 21... for a single FOUNDATION Fieldbus H1 or PROFIBUS PA segment 23V DC, 500mA power supply, supporting the concept of high-power trunk lines.

It provides electrical isolation and short-circuit protection to ensure that the section continues to operate in case of a fault, and supports hot-swappable maintenance.

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

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

Compatible with redundant power supply configurations, supports advanced diagnostic modules, and is easy to integrate with FieldConnex systems.

Application scenarios

HCD2-FBPS-1.23.500 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 sensor and actuator networks), 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.
