Why Choose the Pizzato CS AT-31X024 Safety Module?
The Pizzato CS AT-31X024 is a configurable safety relay module with instantaneous and delayed safety outputs designed for emergency-stop circuits, movable guard monitoring and safety sensor applications. As part of the Pizzato CS AT-3 series, it supports safety applications up to Category 4, PL e and SIL CL 3, making it suitable for demanding industrial machine-safety systems.
The CS AT-31X024 provides 2 normally open instantaneous safety contacts together with 1 normally open delayed safety contact. Its delayed output can be configured across a 0.3–3 s range in 0.3 s steps, allowing controlled delayed disconnection where machinery requires additional time before a safety-related output is released.
Operating from a 24 V AC/DC supply, the CS AT-31X024 supports one- or two-channel safety inputs and automatic, manual or monitored start configurations. The X-version incorporates removable connectors with spring terminals, simplifying installation and servicing within industrial control panels.

Reliable Safety Monitoring for Industrial Machinery
Safety relay modules such as the Pizzato CS AT-31X024 monitor safety-related input devices and control downstream contactors or other safety actuators. Dual-channel monitoring can detect relevant circuit faults while the feedback loop allows external switching devices to be monitored before machinery is permitted to restart.
The delayed safety output is particularly useful where a controlled stopping sequence is required. Two safety outputs operate instantaneously while the third safety contact opens after the configured delay, allowing the safety system to coordinate functions that must remain active briefly while hazardous machine movement comes to a controlled stop.
Typical Applications
- Emergency-stop safety circuits.
- Movable machine guard monitoring.
- Safety switch and magnetic safety sensor monitoring.
- Machinery requiring delayed safety-output disconnection.
- Industrial production and packaging machinery.
- Automated manufacturing and machine-safety systems.
