Typical Specifications Parameter Specification / Value Product Type Distributed I/O Controller / Network Interface Unit System Family ABB Freelance DCS / AC 800F I/O Station Main Processor 32-bit RISC Processor Memory Work Memory: Typically 512 KB (for program and data) Primary Communication PROFIBUS DP (compliant with EN 50170), supports DP-V1 extensions. Typically operates as a DP Slave to a master controller (e.g., AC 700F/AC 800M). Configuration Interface Front RS-232 service port for local commissioning and initial setup. I/O Connection Connects to S800 I/O modules via an internal high-speed backplane bus. Maximum Expandable I/O Dependent on configuration and cycle time; typically supports tens to hundreds of S800 I/O channels. Supported I/O Modules Full S800 Series range: • DI/DO (e.g., NDIO, NDOA...) • AI/AO (e.g., NAIO, NAOA...) • Counter, Serial Communication, etc. Power Supply 24 V DC (typically supplied via a system power module like NPSA-01) Power Consumption: Typically 5 - 10 W. Real-Time Clock Integrated, with battery backup (typically a replaceable lithium cell). Status Indication Multiple front-panel LEDs for: • Run/Fault status • PROFIBUS DP communication status • Station configuration status Configuration & Programming Hardware configuration, parameterization, and assignment of Function Block Diagrams (FBD) using ABB Automation Builder for Freelance. Firmware Storage Stored in Flash memory, updatable via service port or network. Operating Temperature 0°C to +60°C (standard industrial grade) Mounting Mounts on standard 35 mm DIN rail, side-by-side with S800 I/O modules. Protection Degree IP20 (for installation inside enclosures only) Certifications & Standards CE, cULus, ATEX (optional), compliant with relevant industrial EMC and safety standards.
