I/O blocks

Efficient transport of signals

I/O blocks from Balluff connect binary and analog sensors and actuators to the control level via a bus. The number of lines is substantially reduced by the use of the blocks.

Moreover, I/O blocks offer additional functions for signal preprocessing and expanded diagnostic options. Different designs and connection techniques enable solutions for a wide variety of applications, even under the most extreme environmental conditions.

Key benefits

  • Simple to install
  • Efficient configuration
  • Continuous diagnostics
  • Individual solutions through a variety of designs and connection techniques
  • Suitable for use under extreme environmental conditions

Product families

  • IO-Link sensor/actuator hubs

    Unique diagnotic levels offer optimum use in harsh environments

    With their rugged housings, our BNI IO-Link sensor/actuator hub series are ideal for use in harsh industrial environments. The I/O blocks are based on M12 or M8 plug connections, making them easy and economical to install and maintain.

    The port-specific single-channel monitoring detects short circuit and overloads, as well as a cable break at the port. This degree of selective diagnosis is unique among I/O blocks.

    Our variant BNI IOL-30 offers the highest functionality with the best flexibility. It combines two blocks into one. With a maximum sensor load current of 500 mA, it's ideal for operating sensors with high current consumption. If configured as an output, up to 2 A is available at the port.

    Features

    • Simple and cost-saving installation and maintenance
    • Detects short circuits, overloads, and cable breaks at the port.
    • Variant BNI IOL-302 for maximum functionality and the best flexibility

  • IO-Link valve interface

    Simply connect decentralized valve terminals

    You can use the advantages of IO-Link with our IO-Link valve interfaces as well. This is because decentrally installed valve terminals and the control level can easily be connected using these components.

    Features

    • Compact adapter housing for direct placement on the valve terminal with minimal space consumption
    • Compatible with pin assignments of various valve terminals
    • Optimized wiring by connection at the control level, using standard 3/4-wire sensor cable
    • Controls up to 24 solenoids

  • Universal IO-Link interfaces

    Unlimited possibilities

    Using our universal IO-Link interfaces, any device with up to 16 in/outputs is open to IO-Link. Use the IO-Link interface to connect pumps, signal lights, control panels, valve terminals, switching units, transfer units, etc. to the control level.

    The module offers the fast IO-Link connection through the standard sensor cable and an open-ended cable. You can integrate up to 16 in/outputs into the controller environment.

    Features

    • Compact adapter housing for direct connection to different devices via IO-Link
    • Universal, fieldbus-neutral
    • Linking to the control level using standard sensor cable
    • Variants available with 8 or 16 input/output signals
    • No cumbersome multiple cabling
    • Saves space, time and money through the lean cabling concept
