The Pilz PSSU E S 2AI RTD (312490) is a dedicated analogue input module designed for precise temperature measurement in industrial automation systems. Offering two channels for resistance thermometer inputs, this module provides a reliable solution for integrating temperature-dependent processes into safety and control architectures.

At its core, the module is optimised for Pt100 sensors, one of the most widely used platinum resistance thermometers (RTDs) in industrial applications. Pt100 sensors, built to the DIN EN 60751 standard, deliver exceptional accuracy and long-term stability, making them a preferred choice for process-critical operations. By supporting these sensors, the PSSU E S 2AI RTD enables consistent and high-quality temperature monitoring across a variety of industrial applications.

The module provides two analogue input channels, allowing simultaneous monitoring of two independent temperature points. This capability is particularly beneficial in systems where multi-zone temperature tracking is required, such as heating processes, cooling circuits, or material treatment systems. The dual-channel design ensures efficient use of I/O resources, reducing the need for multiple separate modules and simplifying overall system architecture.

In terms of durability, the module complies with EN 60068-2-14 standards, which test performance under varying ambient temperature conditions. This ensures the PSSU E S 2AI RTD can withstand industrial environments where fluctuations in operating temperature are common, maintaining stable and accurate sensor readings at all times.

As part of the PSSu modular I/O platform, this analogue input module can be easily integrated into broader Pilz control systems. The modular design allows engineers to add or remove I/O units as required, supporting scalability and customisation for applications of all sizes. This flexibility makes the module well-suited for industries ranging from automotive manufacturing and chemical processing to food production and energy systems, where reliable temperature monitoring is critical.

The PSSU E S 2AI RTD also contributes to the overall safety of industrial systems. By integrating temperature data into safety controllers and logic, operators can implement automated responses to overheating, cooling failures, or other temperature-related risks. This proactive monitoring helps prevent equipment damage, maintain process quality, and safeguard personnel.

In summary, the Pilz PSSU E S 2AI RTD (312490) is a robust and precise input module that enhances the functionality of PSSu I/O systems by adding high-quality temperature measurement capabilities. With features such as dual RTD channels, Pt100 sensor compatibility, compliance with international standards, and flexible modular integration, it is an indispensable solution for industrial environments requiring accurate, reliable, and safety-focused temperature monitoring.
