Description

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, they provide customers with greater flexibility to add sensors, customise channels and control more auxiliary functions.

The E888 expander inputs Include 8 Thermocouple Inputs (EGT), 8 AV Variable Voltage Inputs (can be used as Temp with external 1K Pullup) along with a couple of Digital Inputs for Speed or Switch Signals

E888 is part of our Comprehensive Vehicle Management System.

Compatible with

• C12X Dash Display/Loggers
• M1 Series ECU – one E888
