ICM-1900 Interconnect Module
The ICM-1900 interconnect module provides easy connections between the DMC-1600 series controllers and other
system elements, such as amplifiers, encoders, and external switches. The ICM- 1900 accepts the 100-pin main
cable and 25-pin auxiliary cable and breaks them into screw-type terminals. Each screw terminal is labeled for
quick connection of system elements. An ICM-1900 is required for each set of 4 axes.
The ICM-1900 is contained in a metal enclosure. A version of the ICM-1900 is also available with servo amplifiers
(see AMP-19X0).
