Why Choose the Pizzato CSAT-30V024-TF3 Safety Module?
The Pizzato CSAT-30V024-TF3 is a compact and reliable safety monitoring relay designed for 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, and interlock devices, ensuring safe and controlled shutdown of machinery in industrial 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 provides a practical output configuration of 2NO instantaneous safety outputs + 1NO delayed safety output, making it suitable for compact safety systems requiring timed shutdown functionality.
The TF3 variant provides a fixed 3-second delay on the delayed safety output, enabling controlled machine run-down after a safety event. This helps reduce mechanical stress in automation systems while maintaining fast emergency response performance. Its DIN-rail housing allows easy integration into industrial control panels and OEM machinery.

Key Features
- Pizzato CS AT safety relay series.
- 24 V AC/DC supply voltage.
- Output configuration: 2 NO instantaneous + 1 NO delayed.
- Integrated fixed-time safety delay function.
- Screw terminal connections for secure industrial wiring.
- DIN-rail mounting for control panel integration.
- Compact design for small to medium safety applications.
Reliable Safety Control for Industrial Systems
The CSAT-30V024-TF3 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 and holds the delayed output for a controlled 3-second interval to support safe machine stopping.
This combination of immediate and timed safety switching improves operator protection while reducing mechanical stress in smaller automation systems requiring short delay functionality.
Typical Applications
- Emergency stop (E-Stop) safety circuits.
- Safety gate and interlock monitoring systems.
- Small industrial automation control panels.
- OEM machine safety systems.
- Light production machinery with controlled stop requirements.
- Basic safety architectures with timed outputs.
