The Pilz PSSu E F 2DO 2-T (314215) is a fail-safe digital output module from the versatile PSSu I/O system, engineered to provide reliable and secure actuation of safety-relevant devices in industrial automation. With its combination of robustness, protective features, and compact modular design, it plays a key role in building scalable, decentralised safety and control architectures.

This module offers two digital outputs (DO) at 24 V DC, enabling direct control of actuators such as contactors, relays, solenoids, and indicator devices. Designed specifically for safety applications, these outputs are short-circuit proof, which helps safeguard against faults in connected loads and wiring. By incorporating potential isolation, the PSSu E F 2DO 2-T ensures separation between safety circuits, reducing the risk of fault propagation and enhancing system reliability.

One of its notable strengths is its resilience when operating with inductive loads. The module is designed to handle voltage peaks up to -50 V when switching off inductive loads, protecting internal electronics from transient spikes and ensuring long-term durability. This makes it particularly suitable for environments where actuators such as solenoids or motor starters are frequently switched.

As part of the PSSu modular I/O platform, the PSSu E F 2DO 2-T integrates seamlessly with other safety and standard modules, offering engineers flexibility in designing systems tailored to their applications. Its plug-in modularity allows quick installation, reconfiguration, or expansion, making it an efficient solution for both new systems and retrofits.

The module is designed for industrial resilience, tested according to EN 60068-2-14 for ambient temperature suitability, ensuring reliable operation under fluctuating thermal conditions. This robustness, combined with its compact design, makes it ideal for installation in diverse environments, from standard production lines to more demanding industrial sectors.

Applications for the PSSu E F 2DO 2-T include safety-critical machine shutdowns, activation of safety relays, signalling devices, and control of actuators within decentralised automation architectures. By providing fail-safe, isolated, and short-circuit-proof outputs, the module ensures compliance with safety standards such as EN ISO 13849 (PL e) and IEC 62061 (SIL 3), supporting high levels of machine and operator protection.

In summary, the Pilz PSSu E F 2DO 2-T (314215) is a robust, fail-safe digital output module designed for reliable actuation of safety devices in industrial environments. With its 2 DC outputs, isolation, short-circuit protection, inductive load tolerance, and modular integration, it offers flexibility, safety, and durability for modern automation systems.
