Hilscher CIFX 50E‑DP PCI Express Communication Interface Card 1251.410 -NIB

The Hilscher CIFX 50E‑DP is a high‑performance industrial PCI Express communication interface card designed to bring fieldbus connectivity to PC‑based automation systems. Manufactured by Hilscher, this compact PCIe x1 card provides a robust and reliable interface between a host computer and a PROFIBUS DP network—one of the most widely used fieldbus standards in industrial automation.
At its core, the CIFX 50E‑DP integrates an onboard communication controller that offloads the PROFIBUS protocol stack from the host CPU, enabling deterministic data exchange with minimal processor overhead. It supports PROFIBUS DP Master, DP Slave, and MPI communication roles (depending on firmware and configuration), making it versatile for a wide range of automation applications. Communication is achieved via an isolated RS‑485 physical layer, typically connected through a 9‑pin D‑Sub port, with LEDs providing real‑time status for system activity and bus communication.
This interface card features dual‑port memory or DMA (Direct Memory Access) for efficient process data transfer between the host PC and the PROFIBUS network. Industrial‑grade isolation (tested to high DC voltages) and optimized operating temperature range ensure reliability in harsh factory environments. Configuration and management tools such as SYCON.net and other Hilscher utilities make integration, firmware updates, and diagnostics straightforward within automation systems.
