Why Choose the Pizzato CSAT-04V120 Safety Module?
The Pizzato CSAT-04V120 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 immediate 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 + 1NC auxiliary contact + 2NO delayed safety outputs, enabling both direct safety switching and timed shutdown sequencing.
With its compact DIN-rail housing and flexible wiring layout, the CSAT-04V120 is widely used by OEM machine builders and automation engineers who require reliable safety logic, expanded output capability, and controlled stop functions in 120 V AC industrial control 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).
- 120 V AC control supply for industrial integration.
- 3NO instantaneous + 1NC auxiliary + 2NO delayed outputs.

Reliable Safety Control for Industrial Systems
The CSAT-04V120 continuously monitors safety inputs such as emergency stop buttons, safety gate switches, and interlock devices. When a safety event occurs, it immediately activates its instantaneous outputs while coordinating delayed outputs to ensure controlled machine shutdown and safe run-down behaviour.
This combination of expanded output switching and timed safety logic makes it suitable for more complex automation systems requiring multiple safety channels and controlled stopping sequences.
Typical Applications
- Emergency stop (E-Stop) safety circuits.
- Safety gate and interlock monitoring systems.
- Industrial automation control panels.
- Complex machinery requiring multiple safety outputs.
- OEM machine safety systems.
- Production line automation and safety sequencing.
