With CAN connectivity and a number of configurable inputs and outputs, they provide customers with greater flexibility to add sensors, customise channels and control more auxiliary functions.

The E888 and E816 expander inputs have medium resolution and update rate, where higher update rates or resolution are required consider using the VIM input expander. 

Compatible with

• SDL3 - only 8 thermocouples on E888
• ADL3 / EDL3 - up to two E888 or E816
• ACL - up to two E888 or E816
• M400, M600, M800, M880 - one E888 or E816
• Depending on the application, some limitations may apply when using an expander with theseECUs. Please check with your dealer for details.
