The Pizzato CSAT-10V024-TF3 is a high-reliability safety monitoring relay designed for advanced industrial machine safety systems operating on a 24 V AC/DC control supply. Manufactured by Pizzato Elettrica, it is engineered to supervise emergency stop circuits, safety gates, interlock systems, and multi-channel safety devices, ensuring fast and controlled shutdown in hazardous environments.
This model belongs to the CS AT safety relay family and is designed for applications requiring Category 4 safety performance, PL e, and SIL 3 compliance. It features an expanded safety architecture with multiple instantaneous safety outputs and delayed safety outputs, enabling flexible integration into complex machinery safety circuits and automated shutdown sequences.
The TF3 version provides a fixed 3-second delay function, making it ideal for applications requiring controlled run-down time before full machine shutdown. This is especially useful in systems where mechanical or process inertia must be safely reduced before de-energisation. Its compact DIN-rail housing ensures easy installation in industrial control panels and OEM machinery systems.

The CSAT-10V024-TF3 continuously monitors safety inputs such as emergency stop buttons, safety gates, and interlock devices. When a safety event occurs, it immediately activates safety outputs and maintains delayed outputs for a fixed 3-second interval to ensure controlled machine shutdown with safe run-down behaviour.
This combination of immediate and timed safety switching improves operator protection, reduces mechanical stress, and supports controlled stopping sequences in automated systems with higher channel complexity.
