Why Choose the Pizzato CSAT-04V230 Safety Module?
The Pizzato CSAT-04V230 is a high-performance 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, and interlock 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 an expanded output configuration with 3NO instantaneous safety outputs + 1NC auxiliary contact + 2NO delayed safety outputs, enabling both direct multi-channel safety switching and timed shutdown sequencing for complex automation systems.
Based on the CS AT safety architecture, the TF versions use selectable timing logic for delayed outputs, making the CSAT-04V230 suitable for controlled stop functions where machinery requires a defined run-down period before full de-energisation. Its compact DIN-rail housing ensures easy integration into industrial control panels and OEM machine 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.
- 3NO instantaneous + 1NC auxiliary + 2NO delayed outputs.
- Suitable for complex safety circuits requiring multiple output channels.
- Supports controlled stop and safety sequencing functions.
Key Features
- Pizzato CS AT safety relay series.
- 230 V AC supply voltage.
- Output configuration: 3 NO instantaneous + 1 NC auxiliary + 2 NO delayed.
- Timed safety outputs for controlled machine shutdown.
- Screw terminal connections for secure industrial wiring.
- DIN-rail mounting for control panel integration.
Reliable Safety Control for Industrial Systems
The CSAT-04V230 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 support controlled machine shutdown and safe run-down behaviour.
This combination of expanded output capability and timed safety logic makes it suitable for more complex automation systems requiring multiple safety channels and controlled stop sequencing.
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 safety sequencing and control.
