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


8 x analogue voltage inputs, 10 bit (4.9 mV) resolution
0 to 5 V, suitable for potentiometers, voltage output sensors and variable resistance (temperature) sensors

8 x thermocouple inputs, 1 ?C resolution
suits K type thermocouples (-200 to 1250 ?C)

2 x cold junction compensation thermistor inputs

4 x digital inputs with frequency measurement and switched capability

2 x switch inputs

Update rate for all inputs 200 Hz, for a second expander 50 Hz

8 x PWM outputs
individually controllable for frequency and duty cycle.
