UNIVERSAL MATH MODULE
UMM-1, UMM-2 SERIES
High and Low Signal Selection
The UMM configured for this mode will accept two, three, or four
analog input signals and output the signal that is either the highest or
lowest of the input signals. To increase the number of input signals,
UMMs may be cascaded by wiring the output of one UMM to the
input of another UMM. Two UMMs wired in this fashion would allow
up to seven input signals. No calibration is required; however, high
and low limits can be set on the output.
Minimum and Peak Hold Signal Selection
In the peak hold operating mode, up to three analog inputs are
monitored. The highest (peak) input signal is remembered, passed
to the output, and held until a higher input signal level occurs. In the
minimum hold mode, up to three inputs are monitored. The lowest
input signal is remembered, passed to the output, and held until a
lower input signal level occurs. A contact closure will reset the output
signal.
Multiple Signal Averaging
The UMM configured for this operating mode will accept two, three,
or four analog input signals and output a signal that is the average
of the input signals. To average up to seven inputs, the primary UMM
accepts four inputs, and its output is wired to the first input of the
secondary UMM. The output of the secondary UMM is the average of
up to seven inputs. The sum can be derived by multiplying the signal
average by the number of inputs.
High/Low Limit Control and Signal Reversal
The UMM may be used as a single input limit control, allowing the
output to be limited to an adjustable upper and/or lower limit. When
the input signal reaches the upper or lower limit setting, the output
will remain at that particular limit setting. The high/low limit function
can also be combined with other operating modes such as high/low
signal selection, peak/minimum hold selection, or signal averaging.
The output of the UMM can be selected to increase as the input
increases (direct action), or the output can be reversed to decrease
as the input increases (reverse action).
Square Root Extraction
When the UMM is ordered with the optional square root function
(SQ option), it may be used as a single input square root extractor,
providing an output proportional to the square root of the input signal.
The square root function can also be combined with other operating
modes such as high/low signal selection, peak/minimum hold
selection, or signal averaging.

WIRING (TYPICAL)
USER-SELECTABLE OPERATING MODES
• All input signals wired to the SIG IN terminals must
be of the same type and range.
• The output signal from the SIG OUT terminal
must be of the same type and range as the input
signals.
• Always disable (jumper to DIS position) any input
that is not to be used.
