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

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

Industrial selector switches are similar to electronic rotary switches.

Use the following signal flow diagram when matching the following information ‪ -With power applied to the system, no sound is heard from either speaker when both microphones are used.

If two symptom are present that are unrelated that means that

Switch problems can be grouped into two categories, problems with the operator and problems with the contacts.

If two loads with different voltage levels had to be switched with a single break type device, you would have to choose a switch that had a minimum of two poles.

The term "throw"in a switch designation indicates if the switch has only a NO or if the switch has both NO and NC contacts.

‪ -The device pictured above is a __________ relay.

‪ -The device pictured above is a __________ type.

Match the five manufacturing categories with the description of each type -Job shop

‪ -The device pictured above is a __________ type.

‪ -The device pictured above is a __________ type.

‪ -The device pictured above is a __________ type.

A DPDT switch contact configuration would have two poles, two NC contacts, and two NO contacts.

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

Which of the following components are NOT a part used in a relay?

Contactor overload contacts are used in the motor power circuit to protect the motor from overload currents.

‪ -The device pictured above is a __________ .

Relays usually have the same pull in and drop out current.

The inrush current is higher than the sealed current for a relay because the air gaps are larger and the armature is made of laminated metal.
