The X20SO4110 is a safety-certified digital output module designed for industrial automation systems, adhering to safety standards up to PL e (ISO 13849) and SIL 3 (IEC 61508). It features four independent safe digital outputs, each rated for 0.5 A nominal current, making it suitable for controlling actuators in safety-critical applications. The module operates on a source circuit configuration, ensuring reliable power delivery to connected devices. With its semiconductor-based design, it eliminates wear-related failures, providing consistent performance over extended operational cycles.
Equipped with Output Type A (high-side/low-side variant), the X20SO4110 supports actuators without reference potential, such as relays and valves. This design offers safety advantages by isolating the actuator from the connection cable in fault scenarios. Key protective features include integrated output protection against short circuits and overloads, current monitoring for real-time performance tracking, and open circuit detection to identify wiring issues. The module also prevents automatic restarts during network errors, enhancing system safety. It interfaces with X20 12-pin terminal blocks for secure and 便捷 connectivity.
Designed for applications requiring fail-safe operation, the X20SO4110 ensures compliance with stringent safety regulations in industries like machinery, automotive manufacturing, and process control. Its semiconductor outputs maintain safety integrity regardless of usage frequency, reducing maintenance needs. The module’s ability to detect and mitigate faults proactively minimizes downtime and risks associated with unexpected system failures. By combining high reliability with flexible integration, it serves as a critical component in safety-oriented control systems, delivering precise and secure actuation for demanding industrial environments.
