Schneider Electric TWDLCDA10DRF Twido Compact Base Controller — 24 VDC Supply, 6 Digital Inputs (24 VDC), 4 Relay Outputs - Compact PLC

Product overview The Schneider Electric TWDLCDA10DRF is a Twido-series compact base controller optimized for small-machine and OEM automation. It integrates an internal 24 VDC supply, six discrete 24 VDC inputs and four relay outputs in a compact housing, providing a space-efficient solution for discrete control tasks with isolated switching capability.

Key specifications

• Manufacturer: Schneider Electric (Twido series)
• Model: TWDLCDA10DRF
• Power supply: Integrated 24 VDC supply (device powered from a 24 VDC source)
• Digital inputs: 6 inputs, nominal 24 VDC (suitable for standard industrial 24 VDC sensors and switch signals)
• Outputs: 4 relay outputs (galvanically isolated relay contacts — verify contact voltage/current ratings in official datasheet)
• Form factor: Compact base/controller for OEM panels and small control enclosures
• Programming: Compatible with Schneider Electric TwidoSuite (confirm software/firmware compatibility prior to commissioning)

Features and benefits

• Integrated 24 VDC supply reduces wiring complexity and the need for external control power in 24 VDC systems.
• Compact 6-in/4-out base I/O suits small machines, simple sequencing and discrete control applications.
• Relay outputs provide galvanic isolation between control electronics and field loads, allowing safe switching of AC or DC loads within relay ratings.
• Small footprint designed for panel-mounting in OEM equipment, packaging machines, conveyors and other compact automation islands.
• Compatible with TwidoSuite for programming, configuration and diagnostics.

Typical applications

• OEM machine control and compact automation islands
• Packaging machines, conveyor segments and material handling equipment
• Simple sequencing and discrete control with isolated outputs required
• Retrofit of legacy small PLCs or controllers

Installation and configuration notes

• Supply the controller with nominal 24 VDC according to Schneider Electric wiring guidelines; confirm correct polarity and adequate current capacity for internal supply plus connected I/O.
• Verify relay contact ratings (voltage and current) in the Schneider Electric datasheet before connecting loads; fit suppression for inductive loads as recommended.
• Use TwidoSuite for program development, upload/download and diagnostics; confirm firmware and module compatibility.
• Follow Schneider Electric installation instructions and local electrical codes for mounting, grounding and wiring to ensure safe operation.
