Specifications Parameter Category Specification Module Type S800 I/O Station Interface & Power Supply Module Product Family S800 Remote I/O Primary Function • Station Communication Interface: Connects the remote station to a fieldbus network via a separate communication module. • Internal Bus Power Supply: Provides a stabilized 5.1 VDC, 1.5A internal bus for all connected I/O modules. • Isolation: Provides electrical isolation between the fieldbus network and the internal I/O circuits. Compatible Communication Modules Interfaces with fieldbus communication modules (e.g., CI873 for PROFIBUS DP, CI854 for PROFINET, CI851 for Ethernet/IP) which plug directly onto it. I/O Module Capacity Can power and manage up to 12 S800 I/O modules in a single station (mounted to its right). Field-side Power Supply Requires an external 24 VDC power source (typically from terminal X5) to power the module's internal electronics and the I/O modules. Output Voltage (Internal Bus) 5.1 VDC Output Current (Internal Bus) 1.5 A (max) Power Dissipation Approx. 6.5 W (typical) Electrical Isolation 1500 V AC (between fieldbus side and internal I/O circuits). Diagnostic Indicators (LEDs) • PS (Power Supply): Indicates 24V external power status. • 5V: Indicates 5.1V internal bus status. • COM: Indicates communication status with the connected fieldbus module. Mounting Mounts on a standard DIN rail. Must be placed as the left-most module in an S800 station. Ambient Temperature 0°C to +55°C (operating) Primary Application Building distributed, remote I/O stations in industrial automation systems to reduce wiring costs and centralize control via fieldbus networks. Certifications CE, UL, cUL, ATEX (for specific conditions and when used with certified I/O modules).
