CAN display module
The CAN display module is a CAN module for displaying CAN J1939 parameters on analogue displays and extends the CAN control system with simple and reliable visualisation of engine data. It is particularly suitable for mobile applications, work machines and aggregates where existing analogue instruments are to continue to be used.
Relevant J1939 parameters are read out via the CAN bus and processed in the module. A typical application is the display of the Ad Blue or catalyst fill level using the SPN 1761 parameter. The output is either an analogue signal or a switching output, enabling flexible connection to different displays and systems.
The CAN module supports an Rshunt in the range from 0 to 100 ohms and offers several output variants for displaying the fill level from 0 to 100 percent. The robust design and clear pin assignment enable easy integration into existing CAN control systems and vehicle electrical systems.
