Pizzato CSAT-13V120 safety relay with 3NO instantaneous and 2NO delayed outputs, 120 V AC supply, Category 4, PL e, SIL 3 for industrial machine safety and emergency stop applications.
£249.17
The Pizzato CSAT-13V120 is a high-reliability safety monitoring relay designed for industrial machine safety systems operating on a 120 V AC control supply. Manufactured by Pizzato Elettrica, it is engineered to supervise emergency stop circuits, safety gates, and interlock devices, ensuring safe and controlled shutdown of machinery in hazardous environments.
This model belongs to the advanced CS AT safety relay family and is designed for applications requiring Category 4 safety performance, PL e, and SIL 3 compliance. It features a robust output configuration with 3NO instantaneous safety outputs + 2NO delayed safety outputs, enabling both immediate stopping and controlled shutdown sequencing for complex automation systems.
The CSAT-13V120 is part of the CS AT-1 series designed for machinery that requires multiple safety output channels and delayed de-energization behavior for controlled run-down. Its compact DIN-rail housing makes it easy to install in industrial control panels and OEM machine systems.

The CSAT-13V120 continuously monitors safety inputs such as emergency stop buttons, safety gate switches, and interlock devices. When a safety event occurs, it immediately activates the instantaneous outputs while managing delayed outputs to ensure controlled machine shutdown and safe run-down behaviour.
This combination of immediate and delayed safety switching helps reduce mechanical stress while improving operator protection and supporting structured stop sequences in automated systems.
