Why Choose the Pizzato CS AT-33X024 Safety Module?
The Pizzato CS AT-33X024 is a compact safety monitoring relay with instantaneous and delayed safety outputs, designed for emergency stop and end-position monitoring of movable guards. Part of the Pizzato CS AT series, it combines 2NO instantaneous safety contacts with 1NO safety contact delayed at de-energisation.
Designed for high-integrity machine safety systems, the CS AT-33X024 provides safety performance up to Performance Level e and SIL 3, with safety functions suitable for applications up to Category 4. Its delayed output allows selected safety-related equipment to remain energised temporarily while machinery completes a controlled stopping or run-down sequence.
The CS AT-33X024 operates from a 24 V AC/DC supply and features four removable connectors with spring terminals. Its slim 22.5 mm wide DIN-rail housing, start input and feedback loop provide a practical solution for space-conscious industrial safety control panels.

Reliable Safety Monitoring with Delayed Switching
The Pizzato CS AT-33X024 combines two instantaneous normally open safety contacts with an additional normally open contact delayed at de-energisation. This configuration allows selected safety functions to respond immediately to an emergency stop or guard condition while another safety-related circuit remains active for the required period during a controlled machine stopping sequence.
The integrated start input and feedback loop support comprehensive safety circuit implementation, while the removable spring-terminal connectors facilitate installation and maintenance. With its compact 22.5 mm housing width, the CS AT-33X024 is particularly suitable for control cabinets where DIN-rail space is limited.
Typical Applications
- Emergency stop circuit monitoring.
- Movable machine guard monitoring.
- Safety door and access gate supervision.
- Position and end-position switch monitoring.
- Controlled machine stopping sequences.
- Applications requiring delayed safety contact de-energisation.
- Machinery with controlled run-down periods.
- Industrial production and assembly machinery.
- Packaging and processing equipment.
- OEM machinery and industrial safety control panels.
