B&R 3AI780.6 Analog Input Module

The B&R 3AI780.6 is a high-performance analog input module from the SYSTEM 2005 product line, engineered for demanding industrial signal acquisition tasks. This module features 8 differential analog inputs with 16-bit resolution for 0 to 25 mA current signals, making it ideal for connecting a wide range of industrial sensors and transmitters.

 

What sets the 3AI780.6 apart is its single-channel galvanic isolation design—each input channel is electrically isolated from the others and from the PLC system, providing superior protection against ground loops and electrical faults. Additionally, each channel includes a separate galvanically isolated 24 VDC encoder power supply (max. 30 mA per channel), simplifying sensor wiring and eliminating the need for external power supplies.

    Key Features & Benefits

    • 8 Differential Current Inputs: Accepts 0 to 25 mA signals from industrial transmitters and sensors for high-precision measurement

    • 16-Bit Sigma-Delta Converter: Delivers exceptional accuracy with ±0.05% basic accuracy at 25°C and zero error of ±0.005%

    • Single-Channel Galvanic Isolation: Each input channel is individually isolated from all others and from the PLC, eliminating ground loops and protecting against electrical faults

    • Per-Channel Encoder Power Supply: Generates an isolated 24 VDC supply (max. 30 mA) for each channel, simplifying field device wiring

    • Two Operating Modes: Supports continuous conversion mode (independent of the application) and trigger mode for simultaneous conversion of all channels via an external command

    • Robust Input Protection: All inputs are protected against accidental connection to supply voltage up to 30 VDC and reverse polarity

    • Comprehensive Status Indication: LED indicators for conversion function, operating mode, filter time, encoder power supply status, and module power supply

    • Full Compatibility: Fully integrates with B&R 2005 system base units and expansion units, supported by B&R Automation Studio

    Operating Modes

    The 3AI780.6 provides two flexible measurement modes for different application requirements:

     
     
    Mode Description Best For
    Standard Mode (Continuous) All channels are converted cyclically, independent of the application. Default filter times: 20 ms at 50 Hz / 16.67 ms at 60 Hz. General-purpose analog signal acquisition and process monitoring
    Trigger Mode All channels are converted simultaneously using an external trigger command. Filter times: 60 ms at 50 Hz / 50 ms at 60 Hz. Applications requiring synchronized measurement across all inputs

    Applications

    The B&R 3AI780.6 is ideal for a wide range of industrial automation applications requiring high precision and complete electrical isolation:

     
     
    Industry Application
    Process Automation Continuous monitoring of pressure, temperature, level, and flow transmitters
    Factory Automation High-precision sensor signal acquisition in manufacturing lines
    System Integration Connecting existing systems to new automation devices with galvanic isolation
    Energy Management Monitoring current loop signals in power distribution and utilities
    Chemical Processing Signal acquisition in electrically noisy environments requiring channel isolation

    System Integration

    The 3AI780.6 is a single-width screw-in module designed for the B&R SYSTEM 2005 chassis. It installs on base units or expansion units and integrates seamlessly with B&R controllers via the system backplane.

    Configuration: Module setup is performed in B&R Automation Studio. Hardware upgrades are available for V2.6 and V3.0.
