M82 - Mezzanine Card with 16 Digital 20 kHz Inputs

M-Module

The M82 is an M-Module with 16 fully isolated digital input channels with latching and comparator capabilities. A current limit for each input guarantees an input voltage range of 0 to 40V. It is designed for industrial automation, medical computers, in-vehicle computers, and embedded computers in transportation.
