The Pilz PSSU E S 2AI I SE (312450) is a precision analogue input module developed for the PSSuniversal I/O system, part of Pilz’s modular automation and safety platform. Specifically designed to process current-based analogue signals, it provides reliable acquisition of process data for both safety-related and standard automation applications.

Equipped with two analogue current inputs, the module allows users to capture continuous values such as flow, pressure, level, or temperature (via transmitters). This capability is particularly valuable in industries where accurate and real-time monitoring of physical variables is essential to maintaining quality, efficiency, and compliance.

One of the key advantages of this module is its flexible input signal handling. It supports both 0–20 mA and 4–20 mA ranges, making it compatible with a wide variety of industrial sensors and transmitters. The 4–20 mA range, commonly used in process control, offers the additional benefit of fault detection, as a drop below 4 mA can signal a line break or sensor malfunction. This feature ensures higher levels of reliability and diagnostic capability in safety-critical systems.

With a 12-bit resolution, the PSSU E S 2AI I SE delivers precise signal processing, allowing operators to detect even small variations in measured values. This level of accuracy supports enhanced process optimisation, predictive maintenance, and improved system responsiveness. By integrating such detailed analogue information into the PSSuniversal system, companies can achieve greater transparency and control over their automation processes.

The module’s compact and modular design makes it straightforward to integrate into new or existing PSSuniversal configurations. Its form factor allows efficient use of cabinet space, while its plug-and-play compatibility simplifies installation and commissioning. In addition, the modular nature of the system ensures easy scalability—users can add, replace, or reconfigure modules as operational requirements change, without significant downtime or redesign.

Pilz’s reputation for safety and reliability is built into the design of the PSSU E S 2AI I SE. By combining analogue input functionality with the proven PSSuniversal platform, this module ensures dependable operation even in demanding environments. It helps companies meet stringent safety standards while also enhancing productivity and operational efficiency.

Typical applications include process industries such as chemical, pharmaceutical, food and beverage, and energy, where accurate analogue monitoring is a cornerstone of safe and efficient operation. For example, monitoring flow rates in a chemical process or pressure levels in a steam system can be achieved reliably with this module, ensuring both quality control and worker safety.

In summary, the Pilz PSSU E S 2AI I SE (312450) provides an effective and versatile solution for analogue signal acquisition within the PSSuniversal I/O system. With its dual current inputs, flexible ranges, 12-bit resolution, and modular integration, it is an essential component for any operation seeking to combine safety, precision, and efficiency in industrial automation.
