Schneider Electric TWDLCAE40DRF Twido Compact PLC Base — 100–240 VAC Supply, 24 Digital Inputs (24 VDC), 16 Relay Outputs - Compact Controller

Product overview The Schneider Electric TWDLCAE40DRF is a Twido-series compact PLC base designed for small- to medium-sized machine control and OEM automation. The unit accepts a universal 100–240 VAC mains supply and provides 24 discrete 24 VDC inputs together with 16 relay outputs, delivering a robust, space-saving control platform with galvanically isolated switching.

Key specifications

• Manufacturer: Schneider Electric (Twido series)
• Model: TWDLCAE40DRF
• Power supply: 100–240 VAC (universal AC mains)
• Digital inputs: 24 inputs, 24 VDC nominal
• Outputs: 16 relay outputs (galvanically isolated contacts)
• Form factor: Compact base/controller for DIN-rail or panel-mounted OEM installations
• Programming: Compatible with Schneider Electric TwidoSuite (verify software version compatibility)

Features and benefits

• Universal AC mains input (100–240 VAC) enables global deployment without local power conversion
• Large discrete I/O count (24 inputs, 16 relay outputs) in a compact footprint reduces panel space and wiring complexity
• Relay outputs provide electrical isolation suitable for switching contactors, solenoids, lamps and other AC/DC loads
• Inputs designed for standard 24 VDC industrial sensors (pushbuttons, proximity sensors, switches)
• Well-suited for machine sequencing, discrete control, and OEM applications where mixed I/O density and isolated outputs are required
• Integration with Twido ecosystem simplifies programming, diagnostics and replacement/upgrade paths

Typical applications

• Packaging machinery, conveyors and material handling systems
• Machine sequencing and discrete control panels
• OEM equipment requiring high-count discrete I/O with isolated outputs
• Retrofit or replacement of legacy compact PLCs in industrial environments

Installation and configuration notes

• Confirm field devices supply nominal 24 VDC for the inputs and follow Schneider Electric wiring diagrams for input wiring and polarity.
• Verify relay contact ratings against load voltage/current and consider suppression for inductive loads per Schneider Electric datasheet.
• Use TwidoSuite for program development, configuration and diagnostics; confirm firmware compatibility prior to commissioning.
• Follow local electrical codes and Schneider Electric installation instructions for safe mounting, grounding and wiring practices.
