Model Description
CC-USB271-CPSN4 Modular USB I/O unit (4 slots)

This new compact, modular USB I/O unit can be connected directly to the USB port on a Windows PC using the included USB cable (USB 3.2 Gen 1 Type-A to Type-C). Take advantage of up to four versatile, low-cost CONPROSYS™ nano Series Ethernet-based remote I/O modules (on sale now) for signal input and output.

Comparison with the conventional

For single endpoints with different operating circuits and sensors, and a small number of total inputs and outputs, I/O modules with the appropriate number of signal inputs and outputs can be combined to form an I/O unit, reducing costs compared to conventional USB I/O units.

This new product can be powered directly via the USB cable from a Windows PC. The safety-focused design includes a flashing LED to notify users if the power consumption exceeds the available USB bus power supply.

Main Features

  • Flexible modular design for effective configurations

    Use up to four versatile, low-cost CONPROSYS™ nano Series I/O modules (including digital, analog, relay, and counter modules). I/O modules can be easily removed without the need for tools.

  • USB bus power operation with no need for an AC adapter

    The USB Type-C port on the product accepts up to 15 W of high-capacity USB power.
    Using the included USB cable to connect the product to a USB 2.0 Type-A port on a Windows PC will provide 2.5 W (5 V, 500 mA) of power, or 4.5 W when connected to a USB 3.0 Type-A port. A PC with a USB Type-C port will provide 15 W of power when connected using a commercially available USB cable (Type-C to Type-C).

  • Insufficient USB power detection function for preventing malfunctions

    If the unit’s power consumption exceeds the power supplied by the connected USB port, the ERR LED will flash to notify users, and the insufficient USB power detection function will stop the unit from starting up. In addition to preventing malfunction due to an insufficient USB power supply during operation, the unit also prevents overcurrent by limiting the power drawn from the connected USB port according to the port specifications.

  • Compact design

    The compact design (110 [W] × 74.8 [D] × 95 [H] mm) enables installation in a wide variety of locations, including easy one-touch installation on DIN rails.

  • Supports Windows driver software

    It is possible to create applications that use Windows driver software provided in API function (DLL) formats, and a diagnostic program that can easily check software and hardware operations is also provided. The popular Python programming language is also supported.
