Why Choose the Pizzato CSAT-04M024 Safety Module?
The Pizzato CSAT-04M024 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 family and is designed for demanding applications requiring Category 4 safety performance, PL e, and SIL 3 compliance. It features a 3NO + 1NC instantaneous output structure combined with 2NO delayed safety outputs, making it suitable for controlled stop sequences in complex automated machinery systems.
With its compact 45 mm DIN-rail housing and robust internal safety architecture, the CSAT-04M024 is widely used in OEM machine building and industrial automation systems where high safety integrity and flexible output timing are required.
Key Advantages
- Certified Category 4 safety performance for high-risk machinery applications.
- Supports PL e (EN ISO 13849-1) and SIL 3 (IEC 61508).
- 24 V AC/DC universal control supply for industrial compatibility.
- 3NO + 1NC instantaneous outputs + 2NO delayed outputs.
- Suitable for emergency stop and guard monitoring circuits.
- Flexible timed safety output for controlled machine stopping.
Key Features
- Pizzato CS AT safety relay series.
- 24 V AC/DC supply voltage.
- Output configuration: 3NO + 1NC instantaneous + 2NO delayed.
- Fixed delay safety function (AT/AR logic with delayed de-energizing outputs).
- Screw terminal or plug-in connector options depending on variant.
- Designed for emergency stop, guard locking, and safety sensor monitoring.
- DIN-rail mounting (45 mm standard housing).
Reliable Safety Control for Industrial Systems
The CSAT-04M024 continuously monitors safety inputs such as emergency stop devices, guard switches, and interlock systems. When a safety event occurs, it immediately activates the instantaneous outputs while managing delayed outputs to allow controlled stopping of machinery.
This combination of high-capacity instantaneous switching and delayed safety output control helps reduce mechanical stress and improves process safety in automated production environments.
Typical Applications
- Emergency stop (E-Stop) safety circuits.
- Safety gate and interlock monitoring systems.
- Industrial automation control panels.
- Machinery requiring controlled stop sequences.
- OEM machine safety systems.
- Robotics and high-performance production lines.
