DESCRIPTION
The UMM Series universal math module is a unique
multifunction micro-computer based interface that can be
utilized to solve a variety of signal selection and manipulation
applications. The UMM-1 is furnished in a unique slim-line
design housing, which saves panel space, and can be
ordered with an optional DIN rail-mounting adapter. The
UMM-2 is a snap-track mounted version with operation
identical to the UMM-1. The UMM models accept up to four
analog inputs, providing a single analog output according to
the operating mode selected. This versatile product allows the
user to select from many operating modes.
