Pizzato CSAT-33M024 safety relay with 2NO instantaneous and 1NO delayed safety outputs for emergency stop and machine guarding applications, 24 V AC/DC supply, Category 4, PL e, SIL 3.
£187.79
The Pizzato CSAT-33M024 is a high-integrity 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, interlock switches, and protective devices, ensuring immediate and reliable shutdown of machinery in hazardous environments.
This model belongs to the advanced CS AT safety relay family and is designed for demanding applications requiring Category 4 safety performance, PL e, and SIL 3 compliance. It provides a robust output configuration with 2NO instantaneous safety outputs and 1NO delayed safety output, enabling controlled stop functions in automated machinery systems.
With its compact 45 mm DIN-rail housing and flexible terminal configuration, the CSAT-33M024 is widely used by OEM machine builders and automation engineers who require reliable safety logic, controlled shutdown timing, and easy integration into industrial control panels.
The CSAT-33M024 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 managing the delayed output to support a controlled and safe machine shutdown sequence.
This combination of fast response and timed safety switching helps reduce mechanical stress while maintaining operator protection in automated production environments.
