Advantages
This extension module offers exceptional reliability and ease of integration for users looking to scale their automation projects. By providing a robust interface between the smart relay and external field devices, it minimizes wiring complexity and enhances system flexibility. The unit is built to meet rigorous international standards, including UL, CSA, and various EN/IEC certifications, which guarantees consistent performance even in demanding operational conditions. Its compact design and lightweight construction make it an ideal choice for space-constrained control cabinets.
Suitable for
Industrial automation and control systems
Small-scale machine automation
Building management and lighting control
Process monitoring and signal acquisition
When it may not be suitable
This module is designed exclusively for use with compatible Zelio Logic smart relays and cannot be used as a standalone controller. It is not suitable for applications requiring high-voltage AC switching or analog signal processing, as it is strictly limited to 24V DC digital and transistor-based I/O operations.
Key specifications
Input type: 8 digital inputs
Output type: 6 transistor outputs
Operating voltage: 24V DC
Compatibility: Zelio Logic smart relays
Weight: 220 g
Certifications: UL, CSA, EN/IEC, GL, GOST
How to use
The SR3XT141BD is installed by connecting it directly to the side of the Zelio Logic smart relay using the integrated expansion connector. Once physically attached, the module is automatically recognized by the relay system. Wiring should be performed according to the provided terminal diagrams, ensuring that the 24V DC power supply is correctly connected to the input and output terminals. After installation, the additional I/O points can be configured and addressed within the Zelio Soft programming environment to incorporate them into your control logic.
What to consider before purchase
Verify compatibility with your existing Zelio Logic base module
Ensure your power supply provides a stable 24V DC output
Check that the transistor output type meets your load requirements
Confirm that the physical space in your enclosure is sufficient for the expansion
Usage recommendations
Always ensure that the power supply is disconnected before performing any wiring or maintenance tasks. Use appropriate wire gauges and ferrules to ensure secure connections and prevent signal interference. Regularly inspect the module for signs of wear or environmental damage to maintain optimal system uptime.
