Whitepaper | Easing digital input integration and functional safety challenges in process and industrial automation applications
As industrial processes become more advanced and connected, factory floor space is typically at a premium and control cabinet and their components must be compact and energy efficient.
As a result, designers of machinery equipment need to find efficient, quiet and compact solutions that meet today's new thermal management constraints, while ensuring the safety and well-being of human workers operating close to new collaborative robots or ‘cobots’.
ST offers a rugged, low-power approach to designing safe, EMI robust solutions based on self-powered digital current limiters.
Takeaways from this whitepaper:
- An overview of the transformation of manufacturing and how new automation control systems interface with the real world
- Functional safety considerations when managing and integrating industrial digital inputs
- ST’s solution and the advantages of a self-powered, non-linear method of digital input integration:
- Functional safety features
- Ease of design integration
- Reliable operation in electrically noisy industrial environments
- Self-powered digital input current limiter ICs and developer resources
After reading this whitepaper, the power and dissipation limitations of using a passive discrete component current limiter input for industrial programmable logic controllers will no longer be an issue. A more robust, low-power approach using ST’s CLT03 series of digital input current limiters yields much less heat generation, enabling greater input module density in space-constrained industrial control cabinets, and ultimately, easing SIL certification for final industrial or building automation applications
