E888 expander module
The E888 expander module was developed to increase the I / O capacity of MoTeC products.
Thanks to the CAN connectivity and a number of configurable inputs and outputs, customers can add sensors more flexibly, adjust channels and control other additional functions.
The E888 expansion inputs have a medium resolution and update rate. If higher refresh rates or resolutions are required, consider using the VIM expansion input. Compatible with
SDL3 - only 8 thermocouples
ACL - up to two
M400, M600, M800, M880 - an E888
Depending on the application, some restrictions may apply when using an expander with these controllers. Please ask your dealer for details.
