The two basic sections of a PLC are the - answerthe central processing unit and the
input/output system
State the primary sections of PLCs . - answerInput modules, (CPU) Central Processing
Unit, Output modules, Programming device, Operator Interface Device
PLC Input modules convert_______________ - answersignals(analog or
discrete/digital) provided by various switches and sensors into logic that can be used by
the CPU
What solid state device is associated with the term "avalanche effect"? - answerZener
diode
The SCR is equivalent to what electronic device? - answerthyristor
What does the PLC Central Processing unit ( CPU) do? - answerevaluates the status of
inputs, outputs, and other variables as it excutes a stored program. The CPU then
sends signals to update the status of outputs.
Describe the function of Output Modules - answerOutput Modules convert control
signals from the CPU into digital or analog values that can be used to control various
outputs
What is the Programming Device used for? - answerit is used to enter or change the
PLCs program or to monitor or change stored values. Once entered the program and
associated variables are stored in the CPU
Discrete inputs and outputs, also referred to as digital inputs and outputs
are_______________ - answereither ON or OFF. High or Low
