Exclusively supports the PROFIBUS - DP protocol in Slave mode, adhering to IEC 61158 - 3 - 10 and EN 50170 standards for PROFIBUS communication. It handles core PROFIBUS - DP Slave functions, including cyclic process data exchange (for real - time control signals), acyclic configuration/parameterization (for Master - initiated device setup), and status feedback (e.g., error reporting, operational state). It complies with PROFIBUS - DP’s slave - master communication rules, such as responding to Master polling within specified timeframes and adhering to data framing standards for reliable signal transmission.

Physical Form Factor: Compliant with standard PCI bus dimensions (approx. 134 mm × 107 mm × 20 mm), designed to fit into standard 32 - bit PCI slots of industrial PCs without requiring custom mounting adapters. Its compact size is optimized for space - constrained industrial control cabinets.

Power Requirements: Operates on dual - voltage supply (3.3 V DC ± 5%, 5 V DC ± 5%) drawn from the PCI bus, with typical current consumption ≤ 350 mA. This compatibility ensures stable operation with standard industrial PC power supplies, eliminating overload risks in multi - card setups.

Integrated Memory: Equipped with on - board dual - port RAM (16 KB typical) for buffering process data. This allows simultaneous access by the PC’s CPU (for data processing) and the card’s dedicated communication controller (for data transmission to the Master), ensuring real - time synchronization between the PC and the PROFIBUS - DP network.

Connector Interface:

PC Connection: Standard PCI edge connector with gold - plated contacts, enhancing corrosion resistance and ensuring stable signal transmission in harsh industrial environments (e.g., dusty, high - vibration settings).

PROFIBUS - DP Connection: 9 - pin D - sub connector (compliant with EN 50170), supporting twisted - pair cabling (PROFIBUS standard: 18 AWG, 2 - conductor + shield) for differential signal transmission. This minimizes electromagnetic interference (EMI) common in factory floors, reducing data transmission errors.

Certifications: UL 508 certified for industrial control equipment, CE marked for electromagnetic compatibility (EMC) per EN 61000 - 6 - 2 (industrial environment), and PROFIBUS - compliant. These certifications validate safe, reliable operation in industrial settings and compatibility with other PROFIBUS - certified devices.
