4 Digital/Analog Inputs, 4 Digital Outputs


  • 4 input ports

  • 4 different input operating modes: digital input, analog input, switch input, resistance measuring

  • 4 digital outputs 12 V / 24 V, 0.5 A

  • C505C-microcontroller

  • High Speed CAN interface acc. to ISO 11898, 1 Mbit/s

  • CANopen® profiles acc. to CiA® specification CiA 301, CiA 401

  • DIN-EN carrier rail mounting (TS 35)

Multi Functional Input Ports
The four input ports of the module can be set by software and/or solder bridges to four different operating modes. The setting can be made for each channel individually. It is possible to select between the modes ‘digital input’ and ‘analog input’ by software in the default configuration of the hardware. If the solder bridges are modified the modes ‘switch input’ and ‘resistance measuring’ will be possible.

Digital Outputs
The four digital outputs of the module can operate with a power supply voltage of 12 V or 24 V.

LED Display and Coding Switch
The status LEDs display the status of the input and output ports, the CAN status and the general module status. The coding switch is used to set the bit rate and the Node-ID.

Intelligent Microcontroller
The CAN-Mini-ADI4/DO4 module is equipped with a C505C-microcontroller with an integrated CAN interface (CAN 2.0B). The firmware is stored in a Flash-EEPROM. An external EEPROM is used to store the data of the module configuration.

The physical CAN layer is ISO 11898-compliant and allows data-transfer rates of up to 1 Mbit/s. It is connected via screw/plug connectors.

CAN Protocols
The module is operating with CANopen according to CiA-DS401.
