The Pilz PSSU E F ABS SSI-T (314275) is a specialised input module for the PSSu modular I/O system, designed to support the integration of absolute encoders into industrial automation and safety applications. With its robust communication protocol, galvanic isolation, and compliance with environmental standards, it provides a precise and dependable solution for position detection and motion control tasks.

At its core, the module is equipped with a dedicated input channel for absolute encoders. This allows machinery to monitor exact position data rather than relative movements, a critical requirement in applications such as robotics, machine tools, packaging systems, and automated assembly lines. By capturing true position values, it ensures high accuracy and reliability in control systems that demand precise feedback.

The PSSU E F ABS SSI-T uses the Synchronous Serial Interface (SSI) standard with RS-422 differential signalling. This configuration provides robust and interference-resistant communication between the encoder and the module. With RS-422’s differential design, the system minimises the impact of electrical noise, which is often present in industrial environments. The result is highly reliable transmission of both clock signals and encoder data, ensuring accurate performance even over longer cable runs.

Another defining feature of this module is its potential isolation between the absolute encoder interface and the power supply. This galvanic isolation prevents ground loops and electrical disturbances from affecting encoder signals or the control system. It enhances safety and ensures that sensitive position data remains uncompromised, contributing to system stability and uptime.

The PSSU E F ABS SSI-T is built for durability, meeting the requirements of EN 60068-2-14 for thermal performance. This certification confirms that the module can withstand fluctuations in temperature common to industrial settings, maintaining consistent reliability under varying environmental conditions.

As part of the Pilz PSSu family, the module integrates seamlessly into modular control and safety systems. Its addition allows engineers to expand their I/O configurations with absolute encoder functionality, supporting scalable and application-specific solutions. Whether for single-axis monitoring or complex multi-axis systems, the module delivers flexibility and compatibility.

In summary, the Pilz PSSU E F ABS SSI-T (314275) combines precise encoder support, robust RS-422 communication, galvanic isolation, and compliance with environmental standards into a compact, modular design. It ensures accurate position feedback, safe operation, and long-term reliability, making it an essential choice for engineers seeking to enhance motion control and safety within their automation systems.
