ABB FAU810

Product introduction

The FAU810 is a high-precision analog input module from ABB, designed to integrate seamlessly with the S800 I/O system and AC800M controller. It serves as a critical interface for measuring and converting analog signals from field devices into digital data for industrial automation systems. With 8 universal channels, it accommodates a wide range of sensors—including current/voltage transmitters, RTDs, and thermocouples—eliminating the need for multiple specialized modules.

This module combines exceptional accuracy (±0.05% for 4-20 mA signals) with robust isolation, ensuring reliable data acquisition even in electrically noisy environments. The FAU810 is engineered for harsh industrial conditions, operating from -40°C to +70°C, making it suitable for power generation, chemical processing, and manufacturing applications where precise measurement of temperature, pressure, flow, or level is essential. Its compatibility with TC560V2 termination units simplifies wiring, enhancing system organization and maintenance efficiency.

Core advantages and technical highlights

Universal channel flexibility

The FAU810’s ability to accept multiple signal types on each channel eliminates the need for module changes when sensor types vary. In a food processing plant, this allows the same module to monitor:

K-type thermocouples in ovens (temperature)

4-20 mA transmitters in mixing tanks (pressure)

Pt100 RTDs in refrigeration units (cold storage temperature)

This versatility reduces inventory costs by 30% and simplifies spare part management.

Industrial-grade accuracy

With ±0.05% accuracy for 4-20 mA signals, the FAU810 delivers precise measurements critical for quality control. In a pharmaceutical batch reactor, it ensures temperature readings (via RTD) are accurate within ±0.1°C, maintaining process parameters within strict FDA guidelines. This level of precision minimizes product waste and ensures compliance with regulatory standards.

Enhanced diagnostics

Advanced diagnostic features of FAU810 include open circuit detection for thermocouples and overrange alerts. In a chemical plant, if a pressure transmitter wire breaks, the module immediately flags the fault via the AC800M controller, triggering an alarm before the process deviates from setpoints. Channel-level LEDs simplify troubleshooting, reducing downtime during maintenance.

Typical application scenarios

In a natural gas processing plant, the FAU810 modules monitor key process variables across the extraction and purification stages. They measure:

Pipeline pressure via 4-20 mA transmitters (connected through TC560V2 termination units)

Compressor discharge temperature using K-type thermocouples

Catalyst bed temperature with Pt100 RTDs

The module’s 2.5 kV isolation protects the AC800M controller from electrical noise generated by compressors, ensuring stable data acquisition even during high-voltage equipment operation.

In a metal smelting facility, the FAU810 withstands extreme ambient temperatures (-10°C to +65°C) near furnaces, monitoring molten metal temperature via S-type thermocouples. Its open circuit detection alerts operators to damaged thermocouple wires, preventing unplanned shutdowns due to lost temperature data. The module’s compact design allows installation in crowded control cabinets, maximizing space efficiency.

Installation, commissioning and maintenance instructions

Installation preparation: Mount FAU810 on a 35 mm DIN rail using the TB820 terminal base, ensuring alignment with adjacent modules (minimum 5 mm clearance). Connect 24 V DC power to the terminal base, verifying correct polarity. Use shielded twisted-pair cable (0.5-1.5 mm²) for sensor wiring, grounding shields at the TC560V2 termination unit. Configure channel types (current, RTD, etc.) via ABB’s Control Builder M software before powering up.

Maintenance suggestions: Inspect FAU810 quarterly by checking channel LEDs—green indicates normal operation, red signals faults. Calibrate annually using a precision signal generator to maintain accuracy, especially for critical applications like pharmaceutical manufacturing. Clean the module with compressed air to remove dust. If a channel fails, swap the sensor to a spare channel and reconfigure via software. Replace the module if multiple channels exhibit drift beyond specifications—use only ABB-approved replacements to ensure compatibility with S800 systems.
