The Pilz PSSU E F DI OZ 2 (312220) is a compact and efficient I/O module within the Pilz PSSu modular system, designed to manage digital signal input and output with high reliability. Combining input monitoring with output control in one unit, this module is well-suited for applications requiring both signal acquisition and safe switching in industrial automation and safety architectures.

At its core, the module provides one digital input that operates at 24 V DC, a standard level for industrial control systems. This allows the module to capture signals from field devices such as switches, sensors, or pushbuttons. By reliably monitoring digital signals, the unit ensures accurate data transmission to the control system, supporting smooth and error-free operation of connected machinery and processes.

In addition to input functionality, the PSSU E F DI OZ 2 includes one 2-pin short-circuit-proof (SC) output, also operating at 24 V DC. This output is designed to withstand electrical faults, ensuring uninterrupted operation even in the event of a short circuit. By protecting both the module and the system, this feature reduces downtime, minimises maintenance requirements, and improves the overall resilience of automation equipment.

The module also benefits from potential isolation between inputs and outputs, an essential feature for protecting sensitive electronics and reducing the risk of electrical noise interference. This ensures stable performance in environments with high electromagnetic interference (EMI) and enhances the reliability of the entire system.

As part of the PSSu modular I/O platform, the PSSU E F DI OZ 2 integrates seamlessly into Pilz’s flexible safety and automation solutions. Its compact design allows it to be combined with a wide range of other input, output, and communication modules to create tailored system architectures. This modularity makes it particularly valuable for industries that need to adapt or scale their systems over time without replacing entire control infrastructures.

Applications for this module are diverse, spanning manufacturing, packaging, logistics, robotics, and process control. It is particularly effective in scenarios where reliable input monitoring and controlled outputs are both needed in a compact footprint. For example, it can capture a machine’s start signal from a pushbutton while simultaneously controlling a safety-related actuator, all within one module.

The module’s compliance with Pilz’s high engineering standards ensures long-term durability, safety, and performance. When integrated into safety-critical applications, it also supports compliance with international safety regulations such as EN ISO 13849-1 and IEC 62061.

In summary, the Pilz PSSU E F DI OZ 2 (312220) is a versatile and reliable digital input/output module offering 24 V DC operation, potential isolation, short-circuit-proof outputs, and compact integration into PSSu systems. It is a key building block for creating scalable, safe, and efficient automation architectures in modern industrial environments.
