Pizzato CSAT-00V230-TF3 safety relay with 2NO instantaneous, 1NC auxiliary, and 2NO delayed outputs, 230 V AC supply, Category 4, PL e, SIL 3, TF3 3-second delay.
Why Choose the Pizzato CSAT-00V230-TF3 Safety Module?
The Pizzato CSAT-00V230-TF3 is a robust safety monitoring relay designed for industrial machine safety systems operating on a 230 V AC control supply. Manufactured by Pizzato Elettrica, it is engineered to supervise emergency stop circuits, safety gates, interlock switches, and protective devices, ensuring fast 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 reliable output configuration with 2NO instantaneous safety outputs + 1NC auxiliary contact + 2NO delayed safety outputs, providing both immediate and timed safety control functions.
The TF3 version provides a fixed 3-second delay function, making it suitable for applications requiring controlled machine run-down or delayed shutdown sequencing after an emergency stop event. Its compact 45 mm DIN-rail housing ensures easy installation into industrial control panels and OEM machinery systems.
Key Advantages
Certified Category 4 safety performance for high-risk machinery applications.
Supports PL e (EN ISO 13849-1) and SIL 3 (IEC 61508).
230 V AC control supply for direct industrial integration.
Screw terminal connections for secure industrial wiring.
Designed for emergency stop, safety gates, and interlock systems.
DIN-rail mounting (45 mm industrial housing).
Reliable Safety Control for Industrial Systems
The CSAT-00V230-TF3 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 3-second timing interval, ensuring controlled machine shutdown with safe run-down behaviour.
This combination of immediate and timed safety switching helps reduce mechanical stress, improve operator protection, and support safe stopping sequences in automated systems.
Typical Applications
Emergency stop (E-Stop) safety circuits.
Safety gate and interlock monitoring systems.
Industrial automation control panels.
Machinery requiring controlled stop and run-down time.
OEM machine safety systems.
Production line safety sequencing applications.
