The Pilz PSSU E S 2AI TC – 312500 is a dedicated analogue input module within the Pilz PSSu I/O system, designed for precise and reliable acquisition of temperature data in industrial automation and safety applications. By providing direct support for thermocouples, the module enables engineers and operators to monitor thermal conditions with accuracy, ensuring both safe machine operation and efficient process control.

Equipped with two independent analogue inputs, the module allows for the simultaneous measurement of two separate temperature points. This makes it particularly valuable in applications where multiple thermal sources must be monitored, such as in heating systems, ovens, furnaces, or production processes involving temperature-sensitive materials. The dual input design ensures compact integration without the need for multiple separate modules, saving cabinet space and reducing costs.

The use of delta-sigma conversion technology enhances measurement accuracy by delivering high-resolution data with reduced noise and improved stability. This ensures that even small variations in temperature are detected and reported consistently, supporting quality assurance and compliance with process standards. With reliable digital conversion, the module enables downstream control systems to react quickly and appropriately to changing process conditions.

Safety and reliability are further reinforced by the inclusion of potential isolation between the analogue inputs. This isolation not only prevents interference between signals but also protects sensitive electronics from faults such as ground loops, overvoltage, or electrical noise. The result is stable, interference-free operation even in electrically demanding industrial environments.

The direct thermocouple compatibility makes the module highly versatile, eliminating the need for additional interface hardware. By simplifying wiring and reducing components, the PSSU E S 2AI TC improves installation efficiency and lowers total system complexity. This capability supports a broad range of industrial thermocouple types, ensuring flexibility across different industries and applications.

Designed for integration within the Pilz PSSu modular I/O platform, the module can be combined with digital and analogue modules to build tailored I/O solutions. Its modularity ensures scalability, allowing users to expand functionality as system requirements evolve, while maintaining compatibility with Pilz’s safety and automation architecture.

Typical applications include monitoring industrial ovens, extrusion processes, injection moulding, packaging machinery, energy systems, and other temperature-critical processes. By enabling continuous, precise, and safe measurement of thermal conditions, the module supports both productivity and operator safety.

In summary, the Pilz PSSU E S 2AI TC – 312500 is a compact and efficient analogue input module designed for thermocouple-based temperature measurement. With dual inputs, delta-sigma conversion, potential isolation, and seamless PSSu integration, it provides an ideal solution for ensuring reliable process control and safety in modern automation environments.
