Schneider Electric TWDLCDE40DRF Twido Compact Base Controller — 24 VDC Supply, 24 Digital Inputs (24 VDC), 16 Relay Outputs, Transparent-Ready - Compact PLC

Product overview The Schneider Electric TWDLCDE40DRF is a Twido-series compact base controller designed for OEM and small-machine automation. It incorporates an integrated 24 VDC supply, 24 discrete digital inputs (24 VDC) and 16 relay outputs, offering a high-density mixed I/O solution with galvanic output isolation. The “Transparent-Ready” designation indicates compatibility with Schneider Electric transparent communication features or modules (refer to product datasheet for specific transparent mode capabilities).

Key specifications

• Manufacturer: Schneider Electric (Twido series)
• Model: TWDLCDE40DRF
• Power supply: Integrated 24 VDC supply (device powered from a 24 VDC source)
• Digital inputs: 24 inputs, nominal 24 VDC (designed for standard industrial 24 VDC sensors and switches)
• Outputs: 16 relay outputs (galvanically isolated relay contacts; verify contact ratings in datasheet)
• Special: Transparent-Ready (supports Schneider Electric transparent communication options—see datasheet for supported modules/modes)
• Form factor: Compact base/controller suitable 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 simplifies wiring in 24 VDC control systems and reduces external power components.
• High-count discrete I/O (24 inputs / 16 relay outputs) in a compact footprint supports dense machine I/O requirements.
• Relay outputs provide galvanic isolation between control logic and field loads, enabling safe switching of AC and DC actuators within relay ratings.
• Transparent-Ready capability allows integration with Schneider Electric transparent communication solutions for simplified network or module interoperability (consult datasheet).
• Compact, rugged design tailored for OEMs, packaging machines, conveyors and other small- to medium-scale automation tasks.
• Compatible with TwidoSuite for programming, diagnostics and firmware management.

Typical applications

• OEM machine control and compact automation islands
• Packaging, conveyor and material handling systems
• Machine sequencing and discrete logic control with isolated output requirements
• Retrofit and replacement of legacy compact PLCs where transparent communication compatibility is required

Installation and configuration notes

• Supply the controller with nominal 24 VDC; confirm correct wiring polarity and adequate power capacity for internal supply and connected I/O.
• Verify relay contact current and voltage ratings in the official Schneider Electric datasheet before connecting loads; apply suppression for inductive loads as recommended.
• Use TwidoSuite for program development and device configuration; confirm firmware compatibility and transparent communication settings if using transparent modules.
• Follow local electrical codes and Schneider Electric installation instructions for safe mounting, grounding and wiring.
