Exam 1: Introduction to Industrial Control Systems, Discrete Control Input and Output Devices

There are two conditions when software is the source of a system problem. One of the condition is when an operator enters incorrect set points or parameters into the program.

Fixed automation machines are designed for a small number of products and FMCs are designed to be flexible and produce a variety of products.

‪ -The device pictured above is a __________ type.

Match the five manufacturing categories with the description of each type -Project

Match the products with the catagories of manufacture systems that would be used t o produce them. -Soft drinks

‪ -The device pictured above is a __________ switch.

In a convergent circuit with three switched inputs, the signal at the output is bad when the switch is on the first convergent input. When the switch is changed to second of the convergent inputs the output is correct. What can you conclude?

Which of the following is true for a 30 second on delay type time delay relay 10 seconds after power applied to the coil?

The instantaneous contacts on a time delay relay operate like NO and NC contacts would on a control relay.

Use the following signal flow diagram when matching the following information ‪ -When switch is changed (position

‪ -The device pictured above is a __________ type.

Commercial and industrial relays generally have the same contact configurations as switches.

Use the following signal flow diagram when matching the following information ‪ -When switch is changed (position

Flow of signal from the output back to the input is what type of signal flow?

Use the following signal flow diagram when matching the following information ‪ -With the left bracket on the left side of the CD player box, the selector switch is placed into position A. When either microphone is used, both speaker perform normally.

Changes in manufacturing are driven primary by a need for increased product quality.

The difference between power and signal flow on a system block diagram is that signal flows from left to right and power flows from right to left.

If a motor must start 15 seconds after the start switch is pressed, and a motor run light must come on when the start switch is pressed, then an on -delay type time delay relay must be used with one set of instantenous contacts.

Match the five manufacturing categories with the description of each type -Repetitive

Which of the following components are NOT found in a typical motor starter.
