An AI sales agent's terminal strip quote, checked before it goes out

An AI sales agent prepares a quote for a control-panel builder who needs a strip of Weidmüller W-Series feed-through terminals on a TS 35 rail: the terminal size, the wire, the load and voltage, the cross-connectors, the end plate, the end brackets and the rail length. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the data sheets and returns a verdict, every reason and the figures it computed.

Scope: Weidmüller W-Series WDU feed-through terminal strips (WDU 2.5, 4, 6, 10, 16 and 35) on a TS 35 rail, with WQV screw cross-connectors, end plates and end brackets. See everything this validator covers

This validator models strips of one WDU terminal size built from the data sheets Weidmüller publishes for those terminals (read October 6, 2026), not just the scenarios shown below.

  • Terminal ratings — for each of the six terminals its width, rated and nominal current, rated voltage, and the smallest and largest conductor its clamp takes, as printed on its data sheet.
  • Cross-connection — WQV screw cross-connectors in 2-, 3-, 4- and 10-pole pieces; the poles they span cannot exceed the terminals on the strip, and the current into the cross-connection cannot exceed the lower of the terminal's nominal current and the rating of the pieces quoted (on WDU 10 and WDU 35 the 3-pole and longer pieces are rated lower than the 2-pole piece).
  • Accessories and length — every data sheet requires an end cover plate; the WAP 2.5-10 plate is listed for WDU 2.5 to 10 and the WAP 16+35 plate for all six; WEW 35/2 brackets are listed for WDU 2.5 to 10 and WEW 35/1 for WDU 16 and 35; the strip length from the data sheet widths must fit the rail and match the length the quote states.

Any WDU strip quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Weidmüller does not publish list prices, so this validator produces no price build-up or line-item quote), ZQV plug-in cross-connectors, the 5-, 6-, 7- and 12-pole WQV pieces listed for WDU 6, other W-Series terminals (double-tier, test-disconnect, fuse, PE), partition plates, markers and test adapters, other Weidmüller terminal families, and strips that mix terminal sizes. Assumptions: the model checks end plate and end bracket type but not how many brackets are quoted; combining the terminal and cross-connector current ratings into one limit is this model's reading of the data sheets; approving a wire larger than the terminal's rated cross-section is a guideline set by this model, not a Weidmüller rule.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A current rating that changes with the piece lengthOnly with care
On WDU 10 and WDU 35 the 2-pole cross-connector is rated higher than the longer pieces, so the limit depends on which pieces are on the quote; it can be written as a rule per terminal and piece, but each one has to be kept in step with the data sheets.		The limit is looked up from the terminal and the pieces quoted, and compared with the current on every call.
Accessories that are listed for some terminal sizes onlyOnly with care
End plates and end brackets differ between the small and large terminals; a product rule per accessory and size works, but every new terminal or accessory adds rules to maintain.		The terminal, end plate and end bracket are in one request and the listed combinations are checked together.
A strip that has to fit the railOnly with workarounds
The length is the sum of widths that differ by terminal, plus plates and brackets, compared with a rail length the quote usually does not carry; it takes a rollup and a separate validation rule.		The strip length is computed from the widths and compared with the rail on every call.
A length the quote states that must match the partsOnly with care
Comparing a typed figure with a computed one is possible but is a separate check that is easy to skip.		The stated length is a field of the request and is compared with the computed length with the other rules.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1The strip has 0 terminals; at least one terminal is needed.
2The wire is 10 mm², but the largest conductor this terminal clamps is 6 mm².
3The wire is 6 mm², above the terminal rated cross-section of 4 mm², although it fits the clamp; a person should confirm the current rating is still met.
4The wire is 0.1 mm², but the smallest conductor this terminal clamps is 0.13 mm².
5The wire is 5 mm², above the terminal rated cross-section of 4 mm², although it fits the clamp; a person should confirm the current rating is still met.
6Each terminal carries 33 A but this terminal is rated for 32 A nominal current.
7The circuit is 900 V but this terminal is rated for 800 V.
8The circuit is 1100 V but this terminal is rated for 1000 V.
9The cross-connectors span 20 poles but the strip has only 15 terminals.
1033 A flows through the cross-connection but it can carry at most 32 A, the lower of the terminal nominal current and the rating of the cross-connectors quoted.
1158 A flows through the cross-connection but it can carry at most 57 A, the lower of the terminal nominal current and the rating of the cross-connectors quoted.
12113 A flows through the cross-connection but it can carry at most 112 A, the lower of the terminal nominal current and the rating of the cross-connectors quoted.
13The strip has no end plate; the data sheet says an end cover plate is required for this terminal.
14The WAP 2.5-10 end plate is not listed for WDU 16 or WDU 35 terminals; their data sheets list the WAP 16+35 end plate.
15The quoted end bracket is not the one listed on the data sheet for this terminal (WEW 35/2 for WDU 2.5, 4, 6 and 10; WEW 35/1 for WDU 16 and 35).
16The strip is 139.5 mm long but the rail is 130 mm.
17The quote states a strip length of 135 mm; the data sheet widths give 139.5 mm.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for a control-panel builder who needs a strip of Weidmüller W-Series feed-through terminals on a TS 35 rail: the terminal size, the wire, the load and voltage, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the data sheets and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 24 WDU 4 feed-through terminals on a 300 mm TS 35 rail. The conductors are 10 mm², at 400 V and 16 A per terminal. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The wire is 10 mm², but the largest conductor this terminal clamps is 6 mm². The strip has no end plate; the data sheet says an end cover plate is required for this terminal. The quote states a strip length of 150 mm; the data sheet widths give 162.4 mm.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a length the quote states that must match the parts, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the wire to 4, the end plates to 1 and the stated strip length to 163.9 mm. It sets the end plate type to WAP 2.5-10.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
