Kussmaul Electronics 091-158 - Manual (Page 2)

INTRODUCTION
The 091-158 is a logic module that permits switching on a load when certain
other circuits are energized. Complete isolation between circuits is maintained.
Two separate logic modes are available and programmed by switches on the
circuit board.
“AND” Logic: In this mode an output is obtained when there is an input at
INPUT 1 and INPUT 2 and INPUT 3. All three inputs must be
present in order to obtain an output
“OR” Logic: In this mode an output is obtained when there is an input at
INPUT 1 or INPUT 2 or INPUT 3. Any input present will create an
output.
Input Signal Polarity: An input signal polarity selector switch permits operating
with inputs that are either a +12 volt or they may be a connection
to ground.
Output Signal Polarity: An output signal polarity selector switch permits selecting
whether the output should be +12 volts or a connection to ground.
CAUTION
The output load, either +12 volts or ground
Must not exceed 2 amperes
