Add digital inputs and outputs to your CAN Network

CAN Digital I/O Expansion Module

The VirtualSCADA® CANio 500 enables easy and quick connection of digital and analog I/O signals to CAN or CANopen systems. The CANio 500 is especially suitable for lab environments, component test stands or in vehicles.

  • 4 Analog Inputs (12 Bit Res. +/- 5 V, 0-10 V or +/- 100 mA)
  • 4 Analog Outputs (12 Bit Res. +/- 5 V, +/- 10 V, 0-5 V or 0-10 V)
  • 4 Digital Inputs, (max. 34 Vdc)
  • 4 Digital Outputs, open-collector (max. 1 Ampere, up to 32 Vdc)

A key feature of the device are the inputs and outputs for digital and analog signals, which can be configured independent of each other. The device has four analog inputs and outputs with a 12 bit resolution. The analog inputs are available with different voltage ranges, as well as with differential input circuits or current inputs. The output voltage range can be individually programmed in fromf -10 V to +10 V for each analog output.

In addition, the device has four digital inputs and outputs. The output voltage range can be selected over a wide range, at this, the switching threshold of the inputs automatically adjusts according to the selected voltage range and the outputs are short circuit protected.

The CANio 500 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 500 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.
