CAN-RS232 Interface Converter

24 V expansion module for standard or in­dus­trial PCs

Key Features

  • Up to 4 RS232 interfaces with D-Sub 9
  • CAN interface acc. to ISO 11898
  • Complies with the CANopen specification acc. to CiA
  • 24 V DC supply with 3-pole phoenix clamp
  • Baud rate and module address configurable via HEX switch
  • Status LED display for module status, CAN and each RS232 channel with Rx- and Tx-display


The aluminium module is extremely compact and offers the possibility of top hat rail mounting. All interfaces and switches for configuration are quick­ly and conveniently available on the front panel. For example, the baud rate and module address can be set con­ve­nient­ly on the front panel and read off at any time.


Signal processing
In addition to the interfaces, the interface con­ver­ter has a powerful microcontroller which handles the acquisition of the sensors, the control of the actuators and the CAN protocol.

CAN interface
The integrated CAN interface enables flexible use at different points and positions in the pro­duc­tion pro­cess and is designed according to ISO 11898.
