◉ A unipolar module can except an input signal ranging from -5 V to
+5 V.
Answer: False... A unipolar module can except an input signal that
varies in the positive direction only
◉ The selector switches on our workstations are close when the
switch is turned to the right.
Answer: True
◉ What is the identifying number in the model number that
established the modules are compatible with the Allen - Bradley SLC
- 500 family.
Answer: 1746
◉ How much memory comes with the processors in the
workstations in our lab.
Answer: 16 K
◉ What is the file extension for a RSLogix project.
, Answer: .rss
◉ What power supply is connected to the normally open push
buttons on the workstation.
Answer: 24 VAC
◉ In order to read I/O for a project what must you do first?.
Answer: Turn on the main switch on the workstation
◉ What is the advantage of choosing a current sensing device over a
voltage sensing device for an analog input.
Answer: The current sensing device is less Susceptible to noise
◉ And or gate operates on the same principle as a:.
Answer: A parallel circuit
◉ There is no difference between a relay schematic and a ladder
logic program.
Answer: False... A relay schematic uses electrical symbols for its
components. A ladder logic program uses PLC instruction symbols
◉ If you want to know when one or both matching bits in two
different words are on you would use the logic instruction.
