Description
Product Introduction
The Schneider Electric Modicon 140XTS00200 is a 40-point removable screw terminal block designed for the Modicon Quantum PLC module family. It serves as the physical interface between field wiring (sensors, actuators, transmitters, and power feeds) and Quantum discrete or analog I/O cards.
The primary benefit of the 140XTS00200 is its swing-out, removable design. By allowing field wiring to remain connected to the terminal block during maintenance, technicians can swap out a faulty or upgraded Quantum module in seconds without disconnecting individual wires or risking wiring errors.

Application Scenarios & Field Experience
The 140XTS00200 is the standard wiring connector across virtually all Modicon Quantum installations worldwide.
- Control Cabinet Assemblies: Terminating multi-conductor control cables for discrete input (24V–230V AC/DC) and discrete output cards.
- Analog Instrumentation Racks: Wiring shielded twisted-pair cables for 4–20 mA current loops, thermocouple, and RTD modules.
- Quick-Swap Maintenance Skids: Allowing fast module replacements in critical 24/7 continuous process lines without re-labeling or landed-wire re-testing.
Field Case Study: During a scheduled shutdown at a paper mill, a 32-point output module needed immediate replacement. Because the field wiring was landed on a 140XTS00200 removable terminal block, the maintenance team unlatched the terminal block, swapped the underlying I/O card, and re-snapped the terminal block in place—reducing downtime from over an hour of wire-tracing to under 3 minutes.

Quality Assurance & Inspection Procedure
Every surplus 140XTS00200 terminal block undergoes physical and mechanical inspection prior to shipment:
- Visual & Structural Audit: Checking the black thermoplastic casing for cracks, chips, or broken retention latches.
- Terminal Screw Inspection: Verifying that all 40 terminal screws turn smoothly and threads are completely free of stripping or corrosion.
- Pin Alignment & Contact Check: Ensuring internal terminal clips maintain spring tension for solid contact with the module header pins.
- Mechanical Latch Verification: Testing side locking tabs to guarantee the terminal block locks securely into the Quantum module faceplate.
- ESD-Safe Packaging: Cleaned, inspected, and securely packed for transport.
Technical Field Tips & Traps
- ⚠️ Screw Clamp vs. Spring Clamp: The 140XTS00200 features standard screw terminals. If your plant standard calls for spring-clamp (tension clamp) wiring connectors, you should specify the 140XTS00201 instead.
- ❗ Proper Torque Control: Avoid over-tightening terminal screws. Exceeding 0.6 N·m (5.3 lb-in) can strip internal threads or pinch thin wire strands.
- ⚠️ Wire Ferrules Recommended: When landing fine-stranded field wires, always crimp insulated wire ferrules onto the ends. This prevents stray wire strands from bridging adjacent terminals on the high-density 40-pin block.
- ❗ Strain Relief Utilization: Always route incoming cable bundles through the lower cable tie channel on the terminal block housing to prevent wire weight from pulling directly on the terminal screws.
Frequently Asked Questions
Q: What is the main difference between 140XTS00200 and 140XTS00201?
A: The 140XTS00200 uses traditional screw clamps to secure wires, whereas the 140XTS00201 uses spring-clamp (tension clamp) connections for faster push-in wiring.
Q: Does the 140XTS00200 come included with Quantum I/O modules?
A: Typically no. Schneider Electric sold Quantum I/O modules and terminal blocks separately so users could choose between screw (140XTS00200) or spring (140XTS00201) connector types.
Q: Can I remove the 140XTS00200 terminal block while the Quantum rack is powered?
A: Yes, Quantum modules support RIUP (Removal and Insertion Under Power). However, be aware that disconnecting a terminal block carrying field voltage (like 120V/230V AC or 24V DC power) will immediately open all connected field loops.
