Schneider Electric Acti9 iSD Signaling Contact 2-100 mA 1CO for Low-Current Circuits

The Schneider Electric Acti9 iSD signaling contact is a precision-engineered auxiliary device designed to provide reliable status monitoring for electrical distribution systems. Specifically optimized for low-current circuits, this component ensures accurate signaling within a range of 2 to 100 mA. It is built to integrate seamlessly with the Acti9 modular range, offering a robust solution for maintaining operational visibility in both commercial and industrial electrical installations.

Advantages

This signaling contact offers high reliability for low-current applications, ensuring that even minimal electrical signals are captured and reported accurately. Its design facilitates easy installation with bottom terminals, allowing for a clean and organized wiring layout within electrical panels. By providing clear status indication, it enhances the overall safety and maintenance efficiency of complex electrical distribution networks, ensuring that operators are promptly informed of the operational state of their modular devices.

Suitable for

• Monitoring status in low-current electrical circuits
• Industrial electrical distribution systems
• Commercial building power management
• Integration with Acti9 modular circuit protection devices

When it may not be suitable

This device is specifically calibrated for low-current applications between 2 and 100 mA. It is not suitable for high-current power switching or circuits that exceed these specified electrical parameters, as doing so may cause damage to the internal contact mechanism.

Key specifications

• Contact configuration: 1CO (changeover)
• Operating current range: 2 to 100 mA
• Terminal type: Bottom terminals
• Compatibility: Acti9 modular devices

How to use

The device is designed to be mounted alongside compatible Acti9 modular components. Installation should be performed by a qualified professional in accordance with local electrical regulations. The unit clips onto the DIN rail, and the bottom terminals are wired to the monitoring circuit. Once installed, the signaling contact automatically tracks the status of the primary device, providing feedback through the changeover contact configuration.

What to consider before purchase

• Verify that your control circuit operates within the 2-100 mA range
• Ensure compatibility with your existing Acti9 modular device series
• Confirm that there is sufficient space on the DIN rail for the auxiliary component

Usage recommendations

Always ensure the power supply is disconnected before installing or performing maintenance on the signaling contact to prevent accidental contact with live parts.
