The E816 Expander module is designed to increase the I/O (input/output) capacity of MoTeC products.


With CAN connectivity and a number of configurable inputs and outputs, it provides 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

  • C185 color logger

  • C125 color logger

  • SDL3 - only 8 thermocouples on E888

  • ADL3 / EDL3 - up to two E888 or E816
