Features and benefits

• Universal AC supply (100–240 VAC) for global deployment without additional power conversion.
• Mixed I/O in a compact footprint: 9 onboard digital inputs and 7 relay outputs suitable for discrete sensing and isolated switching.
• Expandable architecture allows incremental growth using Twido expansion modules, minimizing upfront hardware cost.
• Relay outputs provide galvanic isolation between control logic and field loads, suitable for switching lamps, solenoids, contactors (within relay ratings).
• Compact design optimized for space-constrained control panels, conveyors, packaging and OEM machines.
• Integration with TwidoSuite for program development, diagnostics and device management.

Typical applications

• Machine sequencing, packaging and conveyor control
• OEM control panels and small automation islands
• Retrofit projects replacing legacy compact PLCs
• Discrete control applications requiring isolated outputs and expandable I/O

Installation and commissioning notes

• Supply the controller with nominal 100–240 VAC per Schneider Electric wiring instructions.
• Ensure field sensors and switches operate at nominal 24 VDC for the digital inputs.
• Verify relay contact voltage/current ratings in the official Schneider Electric datasheet before connecting loads; apply recommended suppression for inductive loads.
• Use TwidoSuite for program creation, uploading/downloading and diagnostics; confirm firmware and module compatibility prior to commissioning.
• Follow local electrical codes and Schneider Electric installation guidelines for safe mounting, grounding and wiring.
