The Pilz PSSU E S 4AO U (part number 312465) is a versatile analogue output module designed for the PSSu modular I/O system, providing reliable signal control and precision for industrial and safety-related applications. With its robust design, high resolution, and potential isolation, it ensures dependable performance in a wide range of automation environments.

This module is equipped with four analogue outputs, making it ideal for applications where multiple control signals are required. The outputs are voltage-based, with a standard 0–10 V range, ensuring compatibility with a wide variety of actuators, controllers, and process equipment. This flexibility allows it to be used for tasks such as speed control of drives, position adjustment in actuators, or setpoint delivery to process systems.

Precision is one of the key strengths of the PSSU E S 4AO U. Each output offers a 12-bit resolution, providing fine granularity in signal output and enabling accurate process control. This level of resolution ensures that even small changes in the analogue output are represented reliably, which is essential for applications that require smooth and precise regulation.

The module also features potential isolation of the outputs, an important characteristic in industrial automation. By isolating each output channel, the system is protected from unwanted electrical interference, ground loops, or faults that could otherwise affect measurement accuracy or compromise connected devices. This enhances both reliability and safety, particularly in installations where sensitive equipment is used.

As part of the PSSu I/O family, the module is designed for straightforward integration into Pilz automation systems. Its modularity allows engineers to combine analogue, digital, and communication modules into customised configurations, optimising space and functionality for the specific needs of their application. Installation and wiring are simple, reducing commissioning time and enabling flexible adaptation to changing requirements.

Practical applications of the PSSU E S 4AO U include machine control, robotics, process automation, and motion regulation. For example, it can be used to control motor speeds, adjust valve positions, or deliver reference values to temperature or pressure regulators. Its ability to deliver precise analogue signals makes it particularly valuable in industries where accuracy, repeatability, and safety are critical.

In summary, the Pilz PSSU E S 4AO U is a powerful and reliable analogue output module that expands the capabilities of the PSSu system. With its four 0–10 V outputs, 12-bit resolution, potential isolation, and modular integration, it provides engineers with a dependable tool for delivering precise control signals across diverse industrial and safety applications.
