  • Payment: 50% advance payment; full payment prior to delivery

  • Express couriers: FedEx, UPS, DHL

Key Features

  • 40 integrated I/O – A practical mix of 24 VDC digital inputs and fast transistor outputs for responsive machine control.

  • 24 VDC power – Typically 19.2–30 VDC input range, making it straightforward to integrate with standard control panels.

  • Transistor outputs (24 VDC) – Suitable for high-speed switching (counters, small solenoids, and indicator stacks in many cases).

  • Built-in serial Modbus – Communicate with drives, HMIs, and I/O blocks using Modbus RTU over RS‑232/RS‑485.

  • Compact DIN-rail design – Saves space in crowded cabinets and keeps maintenance simple.

  • Status LEDs – Clear front-panel indication for RUN/STOP and I/O state, which helps technicians diagnose issues faster.

  • Twido ecosystem – Compatible with common Twido accessories; Ethernet connectivity is typically achieved via the TWDNOI10M3 module.

Technical Specifications
Brand / Model Schneider Electric TWDLMDA40DTK (Twido compact PLC)
HS Code 8537.10 (Boards, panels, consoles for electric control, ≤1000V)
Power Requirements 24 VDC nominal (typically 19.2–30 VDC)
Integrated I/O 40 points (digital inputs and 24 VDC transistor outputs)
Output Type Transistor (24 VDC), fast switching for high-frequency signals
Communication Interfaces 1x serial port (RS‑232/RS‑485, Modbus RTU); Ethernet typically via TWDNOI10M3 (optional)
Programming TwidoSuite (legacy); migration commonly to EcoStruxure Machine Expert – Basic
Operating Temperature 0 to 55 °C (typical for Twido family)
Installation Method 35 mm DIN-rail; panel mounting possible in enclosed cabinet (IP20)
Application Fields

This model is commonly found on legacy and mid‑life equipment. It appears to be a good fit where fast digital control and simple fieldbus are required:

  • Packaging machinery, case erectors, labelers, and cartoners

  • Material handling lines and conveyors needing high‑speed sensing

  • Compact pumping stations, dosing skids, and utility panels

  • Textile, printing, and woodworking machines with discrete I/O

  • Retrofit projects aiming to keep Twido-based control logic intact

“We swapped in a TWDLMDA40DTK on a palletizing cell and were back in production the same shift. Wiring and Modbus comms matched our existing layout, which saved us a truckload of time.” — Maintenance Supervisor, Food & Beverage OEM

Advantages & Value

  • Continuity for installed base – Ideal for maintaining Twido systems without redesigning panels or rewriting code.

  • Lower integration effort – Serial Modbus and 24 VDC I/O keep wiring and device mapping straightforward.

  • Procurement flexibility – We can typically source new surplus or fully tested units to meet urgent downtime needs.

  • Compatibility – Works with common Twido accessories and HMIs; migration paths to Modicon M221/M241 exist when planning upgrades.

  • Total cost awareness – Minimizes engineering hours and avoids unnecessary machine requalification in many cases.

Installation & Maintenance

  • Cabinet & environment – Mount on 35 mm DIN rail in an enclosure; allow ventilation space top/bottom; avoid high vibration and moisture.

  • Power & wiring – Use regulated 24 VDC supply; separate high-voltage and signal wiring; provide appropriate overcurrent protection.

  • I/O connections – Label commons, keep sensor returns clean; transistor outputs should drive 24 VDC loads within rated current.

  • Grounding – Bond panel ground properly; maintain shield terminations for serial/field devices to reduce noise.

  • Routine maintenance – Periodic dust removal, check terminal tightness, verify backup/retentive data. Firmware updates are uncommon on legacy Twido, but keeping software versions aligned with your backups is good practice.

If you’re planning a phased upgrade, one thing I appreciate is starting with communications: adding an Ethernet module (such as TWDNOI10M3) can simplify monitoring while leaving the control core intact.

Quality & Certifications

  • CE compliant

  • cULus listed (typically for the Twido family)

  • RoHS compliant

  • Manufactured under ISO 9001 quality systems

  • Manufacturer warranty is typically 18 months from shipment; our store warranty: 365 days

Commonly Paired Accessories

  • TWDNOI10M3 Ethernet communication module (for Modbus TCP/diagnostics)

  • Twido digital and analog I/O expansion modules (when additional points are needed)

  • Programming/communication serial cables compatible with TwidoSuite environments

Need a specific revision or batch?

Share your current controller label or a cabinet photo. It usually helps us match the exact I/O type, port options, and terminal style so replacements go in without rewiring.
