CAN Digital I/O Expansion Module

Add digital inputs and outputs to your CAN Network

CAN Digital I/O Expansion Module

The VirtualSCADA® CANio 250 enables easy and quick connection of digital input and output signals to CAN or CANopen systems. The CANio 250 is especially suitable for lab environments, component test stands or in vehicles.

  • 8 Digital Inputs, (max. 5 Vdc)
  • 8 Digital Outputs, open-collector (max. 30mA, up to 5 Vdc)

The 16 TTL compatible I/O points can be individually configured as input or output in groups of 8. The CANio 250 is designed as a self-starting CANopen slave with all settings, such as Node-ID or default values, stored in the device.

Setup of the CANio 250 for different applications can be done either by loading configuration data via a CANopen master or by sending configuration messages in a pure CAN network or offline via the free CANio configuration tool. Configurations that have been created with the CANio configuration tool can be saved as a project.
