Description

SIEMENS 6MF28110AA00 Input Module

Product Dimensions：

The Siemens 6MF2811-0AA00 (also written as 6MF28110AA00) is a high-performance DI-8110 Digital Input Module. It is a core expansion component of the SICAM A8000 series, which is Siemens’ flagship platform for modular remote terminal units (RTUs), smart grid automation, and substation control systems.

Product Detailed Description

The DI-8110 (6MF2811-0AA00) module is engineered to safely, quickly, and cleanly acquire binary/digital signals from the field. It features 16 digital inputs structured in a logical 2×8 channel architecture. Optimized for substation and harsh industrial environments, it features an ultra-fast response time of 1 ms, allowing the master controller to record time-stamped alarms, event sequences, and device statuses with millisecond precision.

Technical Parameters

Product Advantages

• Ultra-Fast Signal Processing: The 1 ms input filter time ensures that critical status changes or fault sequences are detected immediately, which is vital for precise Sequence of Events (SOE) logging in power grids.
• Structured & Compact Design: The 2×8 configuration handles high-density wiring efficiently, saving space in control cabinets while keeping channel groups clearly organized for troubleshooting.
• Rugged Field Connections: Standard screw terminals ensure mechanical stability and gas-tight wiring connections, minimizing risk of contact failure in high-vibration or retrofitted environments.
• Extreme Environmental Adaptability: Built to meet strict substation standards (IEC 60870-5-101/104 ecosystem requirements), giving it high immunity against electromagnetic interference (EMI).
• Seamless Integration: It connects natively to the SICAM A8000 master modules (like CP-8021 or CP-8050) via the integrated side-by-side backplane bus.

Important Considerations & Precautions

• Voltage Integrity: This module is explicitly rated for 24 V DC logic inputs. Do not connect higher substation voltages (such as 48V, 110V, or 220V DC) to this module, as it will cause permanent hardware damage. (Siemens offers alternative modules like DI-8111 for 48/60V or DI-8113 for 220V).
• Electrical Work Safety: Only qualified automation technicians or industrial electricians should install or replace this module to avoid electrical accidents or bus interruption.
• Firmware Coordination: When adding this module to an existing SICAM A8000 rack, ensure the master processor module’s firmware is updated to recognize the hardware variant.
• Electrostatic Discharge (ESD): Always wear a grounded ESD wrist strap when handling the card or sliding it onto the DIN rail assembly to protect internal semiconductor components.

Product Applications

The 6MF2811-0AA00 is widely used across power distribution and infrastructure industries:

• Substation Automation: Capturing auxiliary switch contacts, circuit breaker positions (open/close), and disconnector statuses.
• Grid Monitoring & Smart Grids: Monitoring alarm chains and fault indicators inside ring main units (RMUs) and transformer stations.
• Renewable Energy Integration: Acquiring operational status signals from wind turbine control blocks and solar inverter stations.
• Infrastructure Telemetry: Relaying critical inputs in railway power supplies, water treatment facilities, and gas pipeline monitoring points.
