Features and benefits

• Universal mains input (100–240 VAC) for global deployment without DC power conversion
• Relay outputs allow safe isolation for switching contactors, solenoids, lamps, and other AC/DC loads
• 14 discrete inputs support common 24 VDC sensors (pushbuttons, proximity sensors, switches)
• Compact footprint reduces panel space and simplifies integration in OEM machines
• Reliable Schneider Electric build quality and integration with the Twido ecosystem for straightforward configuration and diagnostics

Typical applications

• Small-machine sequencing and logic control
• Packaging, material handling, and conveyor control
• OEM control panels requiring isolated outputs and universal AC compatibility
• Replacement or upgrade of legacy compact PLCs in industrial machinery

Installation and configuration notes

• Ensure field input devices supply 24 VDC for inputs; verify wiring and polarity per Twido installation guide.
• Verify relay contact ratings and load requirements against Schneider Electric datasheet before connecting inductive or high-current loads.
• Use TwidoSuite for program development, troubleshooting and firmware compatibility checks.
• Follow all applicable local electrical codes and Schneider Electric installation instructions for safe mounting, grounding, and wiring.
