Features and benefits

• Universal AC supply (100–240 VAC) enables worldwide deployment without external voltage conversion.
• Expandable I/O architecture lets you add Twido expansion modules to increase input/output count as system needs grow.
• Relay outputs provide galvanic isolation, suitable for switching small AC or DC loads (confirm load ratings against datasheet).
• Compact footprint ideal for space-constrained control panels and OEM equipment.
• Integration with TwidoSuite simplifies programming, diagnostics and maintenance.

Typical applications

• Small machine sequencing, packaging machines and conveyor segments
• OEM control panels requiring a compact, expandable controller
• Retrofit applications replacing legacy compact PLCs with limited I/O requirements
• Discrete control tasks where isolated relay outputs are preferred

Installation and configuration notes

• Observe correct mains wiring for 100–240 VAC and follow Schneider Electric installation instructions.
• Ensure connected sensors and field devices provide/operate at nominal 24 VDC for digital inputs.
• Verify relay contact voltage/current ratings in the official Schneider Electric datasheet before connecting loads; use suppression for inductive loads per manufacturer guidance.
• Use TwidoSuite for program creation, uploading/downloading and diagnostics; confirm firmware compatibility before commissioning.
• Follow applicable local electrical codes and best practices for grounding, mounting and wiring.
