Total Cost of Ownership Calculator for Marshalling

This worksheet will help you compare the potential benefits of using MTL SUM5 Smart Universal Marshalling solution compared to traditional marshalling solutions.

Based on the information provided on your specific marshalling application, the tool will display capital and operating expenditure, including a breakdown of the marshalling cabinet costs.

  1. Input your information by typing in details or selecting from the drop down menu in the green boxes.
  2. If clarification is needed, roll your mouse over the text to see if a pop-up help box appears.
  3. Once you define your requirements, your results will be calculated and displayed
  4. To have a printable PDF of your calculation, complete the "Create my report" form and click "Submit".

Cabinet information
Customer/project name will help you manage the comparisons calculated and you can select the currency to use for the comparison. Information on where the marshalling cabinets will be built and the end user location are used to select appropriate labour rates or you can enter your own labour rates by selecting the custom option. Cabinet wiring time and design information can be entered or use the default values to calculate the savings.

Cabinet wiring
Time/wire connection (minutes)
How much time is required per terminal connection? Enter value in minutes. A typical figure would be '6'.
Cabinet design information      
Maximum cabinet loading percentage
What percentage of the total cabinet space can be allocated to equipment? The remaining balance of space will be left empty for future expansion.
Carriers/column
You can have a maximum of 8 carriers per column in a 2m high cabinet.
Columns/cabinet side
You can have a maximum of 3 columns per cabinet side.
Cabinet sides
Select single or double sided cabinet.
Generally double sided.
Total channels/cabinet
This value will be calculated based on above input.
  Configuration module
The configuration module is used to program advanced functions such as the type of input on a DI, for example "NAMUR input", "dry contact", or "Voltage input".
It is also used for diagnostics and common relays, which can be used for alarms.

* You can choose not to use such a module.
This will represent lowest cost, and configuration of the I/O modules will be done via push button on each I/O module.
Advanced programming functions will however not be available, and all modules will be used with standard settings, which fit most applications.
* You can use one module per cabinet (i.e. you move it around for configuration).
This is a low cost option, and allows you to use advanced programming functions when needed.
* You can use one module per carrier (i.e. one module will be mounted on each carrier).
This allows you to use it for advanced programming, diagnostics and custom alarming.
The downside is that the costs are multiplied with the number of carriers in use.

IO types and product lifetime

Enter the number of IO of each type for Intrinsically Safe (IS) and General Purpose marshalling in the isolation column where this is required or in the passthrough column when isolation is not required. If surge protection is required, enter the number of channels requiring surge protection each IO type. Additionally you can define the product lifetime. This will allow both a MTL SUM5 and traditional marshalling cabinet designs to be assessed and a cost comparison to be provided.

Lifetime        
  Product lifetime - years
The annual maintenance costs are calculated and multiped by the product lifetime to calculate the total costs of ownership. See TCO sheet.
