Product Introduction
The Schneider Electric 140XTS00200 is a 40-point screw terminal block for Modicon Quantum PLC systems. It provides the field wiring interface for a wide range of Quantum discrete and analog I/O modules, letting you terminate plant signals cleanly and maintain signal integrity in control panels.
This terminal strip is chosen because it matches the 40-pin connector layout used by many Quantum I/O cards, supports screw-type terminations for reliable connections under vibration, and carries standard industrial marks (UL/CSA/CE) when installed per OEM rules. It is discontinued but supported through end-of-service in 2030, so verified surplus or refurbished stock is a practical way to maintain or expand existing Quantum racks.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Intermittent I/O on a channel | Loose screw terminal or broken strand | ✅ High | Gently tug each wire; check for shiny copper exposure; re-torque terminal screws | Re-terminate suspect wires; use ferrules for stranded conductors |
| Multiple channels dead on one module | Terminal block misaligned or not fully seated | ✅ High | Visually confirm terminal block is fully engaged with module connector; check for bent pins | Reseat terminal block; inspect for damaged pins; replace if bent |
| One channel always OFF | Open circuit at terminal or jumper misconfiguration | ✅ Medium | Measure continuity from terminal to module pin; check jumper kit (140XCP60000) wiring | Fix open circuit; verify jumper pattern matches wiring diagram |
| Noise on analog signals | Poor shielding/grounding at terminals | ❌ Medium (installation issue) | Inspect shield termination; verify single-point ground strategy | Re-terminate shields per OEM practice; separate analog and power wiring |
| Burnt/melted terminal | Overcurrent or wrong wire size | ❌ Medium (application issue) | Inspect terminal for discoloration; check wire gauge vs spec | Replace terminal block; correct wire size and protection upstream |
| Corrosion on terminals | Humidity or chemical exposure | ❌ Low (environmental) | Visual inspection for green/white corrosion deposits | Replace terminal block; improve enclosure sealing or add desiccant |
If you are unsure, send photos of the terminal block, wiring, and module type. We can review pinout alignment and termination quality before you power up.

Frequently Asked Questions (FAQ)
Q: Is the 140XTS00200 still available new from Schneider?
A: No. Schneider discontinued this terminal block (discontinued 2022–2024 depending on region) with end-of-service in 2030. You will find New Surplus (factory-sealed) or Refurbished (inspected, clean, no damage) units through specialized distributors.
Q: What is the difference between New Surplus and Refurbished for a terminal block?
A: New Surplus means OEM original, sealed, with original packaging and labels. Refurbished means the unit was removed from service, cleaned, inspected for cracked housings or damaged terminals, and verified mechanically sound. We list the exact condition per unit.
Q: Which Quantum modules use the 140XTS00200?
A: It is the standard 40-point terminal strip for many Quantum I/O modules, including 140ACI, 140ACO, 140DDI, 140DDO, 140AVI, 140AVO, 140DAI, 140DAM, 140DRO, 140DRA, 140DRC, 140DSI, 140DVO, 140EHC, 140ERT, 140SAI, 140SDI, 140SDO, 140AMM, 140ARI, 140ATI, and 140DDM families.
Q: Are jumpers included with the 140XTS00200?
A: No. The terminal block ships without jumpers. If your wiring scheme requires commoning terminals, you must purchase the jumper kit separately (140XCP60000).
Q: Can I use this terminal block with non-Quantum modules?
A: No. It is designed for the Modicon Quantum 40-pin connector layout. Using it with other PLC families risks misalignment, bent pins, and unreliable connections. Match the terminal block to the module family.
Q: What wire sizes work with these screw terminals?
A: Follow the Quantum hardware guide for the specific I/O module you are wiring. In general, use stranded copper conductors with ferrules or properly tinned ends, and torque screws to the OEM spec to avoid loose connections or cut strands.
Q: What warranty do you offer on obsolete stock like this?
A: Standard coverage is 1 year on New Surplus and Refurbished units, with a clear RMA process. We document incoming condition and inspection results so you know exactly what you are installing.
