    The Allen Bradley AB 1746-NI4/B modules are specifically engineered for applications requiring high-precision analog signal handling. They are ideal for integration into complex industrial control systems where reliable and accurate data transmission is critical.

    Featuring a compact design with robust isolation and overvoltage protection, these modules ensure stable operation even under harsh industrial conditions. Their wide common mode voltage range supports a variety of measurement scenarios.

    With 4 input channels, each capable of measuring currents from -20 to 20 mA, the AB 1746-NI4/B modules offer versatility in terms of sensor compatibility. This makes them suitable for monitoring temperature, pressure, flow rates, and other continuous physical parameters.

    On the output side, the modules can provide controlled voltages from -10 to 10 V DC, enabling the adjustment of actuators, valves, and other devices. The ability to handle both input and output tasks in a single module streamlines system architecture and reduces complexity.

    These modules are equipped with built-in communication ports for various protocols, including EtherNet/IP, DH+, DH-485, and RS-232, facilitating seamless integration with a wide range of industrial networks. This ensures that data can be easily shared across different devices within an automated system.
