3.

Which of the following are “wiring concepts” for machine automation?
- Discrete
- Passive Connectivity
- Distributed I/O
- De-centralized Serial
- All of the above
Correct Answer

A. All of the above

Explanation

Discrete is the traditional terminal block, point-to-point wiring.

Passive is a modular-concept that provides Input and Output conectivity only with no ability to perform logic functions.

Distributed I/O is baically Passive I/O but with intelligence to perform logic functions - such as in a programmed PLC - built in.

Serial would apply to any "fieldbus" technology such as DeviceNet, Modbus, RS232, RS485, Profibus, EtherNet/IP, etc.

Rate this question:
4.

Using a 5 pole passive distributor block - such as the one in question number 2 - which pins are normally for the signals S1 & S2?
- 1 & 4
- 2 & 3
- 1 & 5
- 3 & 4
- 2 & 4
Correct Answer

A. 2 & 4

Explanation

The contact layout for Murr's female M12 connectors typically requires that Pin 2 is for (N/C)/(S2) and Pin 4 is for (N/O)/(S1)

Rate this question:
5.

Discrete wiring still offers what one advantage over serial bus communications?
- Number of signals
- Distance of wiring
- Signal transfer speed
- Ease of installation
Correct Answer

A. Signal transfer speed

Explanation

Serial communication speed is determined by the networks specific data transfer rate. That is further reduced by the amount of "traffic" created by devices on the network.

But discrete point-to-point wiring transfers its signal(s) virtually instantaneously since each individual wire transmits electrons in metal at about 3000 km per second. To put that in perspective, the speed of light is about 300000 km per second.

6.

What are the main families for Murr passive distributors?
- Exact8, Exact12, MVP12-Metal
- Cube67, CUBE20, Impact67
- MVC, Exact12, Exact23
- All of the above
Correct Answer

A. Exact8, Exact12, MVP12-Metal

Explanation

This can be found on the inside cover of Murr's Passive Connectivity Overview (PDF) that was attached to the email that contained the link to this quiz. This is a great document to email prospective customers of Murr's Passive Distribution technology!

Rate this question:
7.

Murr's Insulation Displacement Connections (IDC) carry which IP rating when properly installed?
- IP20
- IP65
- IP67
- IP69K
Correct Answer

A. IP67

Explanation

If you clicked on the link contained in the question and then checked an individual IDC connectors specifications you would see that IP rating is 67 when plugged in and screwed down (EN 60529).

Rate this question:
8.

How many standard cable types does Murrelektronik offer? (select all that apply)
- PVC
- PUR/PVC
- PUR
- PUR Robotic
Correct Answer(s)

A. PVC
A. PUR/PVC
A. PUR
A. PUR Robotic

Explanation

This can also be found in Murr's Passive Connectivity Overview (PDF).

Rate this question:
9.

How many ways can Murrelektronik M12 and M8 connectors be verified for proper installation?
- Audible
- Visual
- Mechanical
- All of the above
Correct Answer

A. All of the above

Explanation

Only Murr offers the handy torque wrench for applying proper connectivity every time! You can SEE the connector being turned as you MECHANICALLY "wrench" it on or off, and you can HEAR it 'click' when it has been tightened to the required torque setting.

Rate this question:
10.

Which of the following are advantages of distribution block wiring? (select all that apply)
- Less cables to return to a control panel
- Reduced installation time
- Easier to trouble shoot faults and make repairs
- Eliminates junction boxes
Correct Answer(s)

A. Less cables to return to a control panel
A. Reduced installation time
A. Easier to trouble shoot faults and make repairs
A. Eliminates junction boxes

Explanation

Any OEMs that still wire their machines with traditional discrete wiring are excellent customers for this technology. Any new application/installation at a user account would also be a good prospective customer.

So remember: MANY PEOPLE DON'T KNOW WHAT THEY WANT UNTIL YOU SHOW IT TO THEM! There's always the chance that some of your prospective customers are not aware that Murr's Passive Distribution technology exist.

Rate this question:
11.

Murr’s 8-way(port), 4-pole distribution boxes can serve a maximum of how many signals? Got to page 3.14.1 of your hard-cover Murr master catalog and notice the 'Number of ports" and the "Signals per port" of each series of passive distribution blocks. Then also check Exact8 distribution blocks specifications.
- 4
- 6
- 8
- 16
Correct Answer

A. 16

Explanation

Murr's 5-pole connections have up to 2 signals per port and most 4-pole connections have 1 signal per port. The exception is the Exact8 series that has 4-pole suppression but still offers 2 signals per port for a total of 16 signals in their 8-port version. This can be found on page 3.12.6 of your hard-cover Murr master catalog.

Rate this question:
12.

What is the most cost effective EXACT12 distribution box for customers needing modular connectivity of the distribution block?
- M23 connectors and M23 home run cable
- M12 multipole and M12 multipole cables
- Plug Terminals and Prewired Cap & Cable
- Overmolded Distribution box with integrated cable
Correct Answer

A. Plug Terminals and Prewired Cap & Cable

Explanation

The most cost-effective EXACT12 distribution box for customers needing modular connectivity of the distribution block is the Plug Terminals and Prewired Cap & Cable. This option provides a convenient solution for connecting various components with plug terminals and prewired cap and cable, reducing the need for additional connectors or cables. This helps to streamline the installation process and minimize costs for customers.

13.

When looking for passive wiring applications, what are indicators on the machine or equipment that provide an opportunity to quote Murr's passive distribution blocks?
- Junction box(es) on the equipment frame
- Large numbers of sensors in a single location
- Large cable trays
- All of the above
Correct Answer

A. All of the above

Explanation

While Junction Boxes are the number one indicator that Murr's Passive Distribution blocks are applicable, cable trays and sensors, as well as valves and other I/O devices clumped together are also good very good indicators.
