The Pizzato CSAT-00V024-TF1 is a high-reliability safety monitoring relay designed for industrial machine safety applications operating on a 24 V AC/DC control supply. Manufactured by Pizzato Elettrica, it is engineered to supervise emergency stop circuits, safety gates, and interlock devices, ensuring safe and immediate shutdown of machinery when a hazardous condition is detected.
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 a mixed safety output configuration with 2NO instantaneous safety contacts + 1NC auxiliary contact + 2NO delayed safety outputs, providing both immediate and timed shutdown control.
The TF1 version provides a fixed 1-second delay function, making it ideal for applications where controlled stopping or sequencing is required after an emergency stop event. Its compact DIN-rail housing ensures easy integration into industrial control panels and OEM machinery systems.
The CSAT-00V024-TF1 continuously monitors safety inputs such as emergency stop buttons, safety gates, and interlock devices. When a safety event occurs, it immediately activates the instantaneous outputs while coordinating delayed outputs after a fixed 1-second timing interval to ensure controlled machine shutdown.
This combination of immediate and timed safety switching helps reduce mechanical stress, improve operator safety, and support controlled stopping sequences in automated systems.
