Pizzato CSAT-30M024-TF3 safety relay with 2NO instantaneous and 1NO delayed output (TF3 3s delay), 24 V AC/DC supply, Category 4, PL e, SIL 3.
£187.79
The Pizzato CSAT-30M024-TF3 is a high-performance 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 conditions.
This model belongs to the advanced CS AT safety relay series and is designed for demanding applications requiring Category 4 safety performance, PL e, and SIL 3 compliance. It features a proven safety architecture with 2NO instantaneous safety outputs and 1NO delayed safety output (TF3 timing class), enabling controlled stop functions in automated machinery systems.
With its compact DIN-rail housing and time-delay safety output configuration, the CSAT-30M024-TF3 is widely used by OEM machine builders and automation engineers who require reliable emergency stop handling and controlled machine deceleration in industrial environments.
The CSAT-30M024-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 activating the delayed output after the configured TF3 timing period, ensuring a controlled shutdown sequence.
This combination of fast emergency response and timed safety output improves machine protection, reduces mechanical stress, and supports safer deceleration in automated systems.

It is used to monitor safety circuits such as emergency stops and interlocks, providing instantaneous outputs plus a delayed safety output for controlled shutdown.
TF3 refers to a fixed delay timing class, typically around 3 seconds, used to delay one safety output during controlled machine stopping.
It complies with Category 4 safety requirements and is rated for PL e and SIL 3 applications.
It operates on a 24 V AC/DC supply suitable for industrial control systems.
It is installed inside industrial control panels on DIN rails for machine safety applications.
Pizzato CS AT safety modules are widely used in industrial automation to ensure reliable emergency shutdown, controlled stopping, and compliance with international safety standards.
