The E888 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, customize channels and control more auxiliary functions.

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