CS FS-20VU24-TF3 Pizzato Safety timer module 1NO+1NC+1CO, category 3

Why Choose the Pizzato CSFS-20VU24-TF3 Safety Timing Module?

The Pizzato CSFS-20VU24-TF3 is a reliable safety timing relay module designed for industrial automation systems requiring controlled delayed de-energizing of safety outputs. As part of the Pizzato CSFS safety relay series, it delivers precise timing control for machine sequencing, safe shutdown logic, and safety interlock coordination.

This model features a TF3 fixed timing function, meaning the delay is factory-set and not adjustable. The TF3 variant is typically used for longer safety timing cycles (multi-second class delay depending on application), making it suitable for controlled stop sequences and delayed safety deactivation in automated machinery. It is widely used in Category 3 safety architectures.

With its compact DIN-rail mounting design and industrial-grade enclosure, the CSFS-20VU24-TF3 integrates easily into OEM machinery control panels, production systems, and automation environments where predictable and repeatable safety timing is essential. It ensures stable operation even in demanding industrial conditions. {index=1}

Reliable Safety Timing for Industrial Shutdown Control

The CSFS-20VU24-TF3 ensures controlled delayed deactivation of safety outputs, helping prevent abrupt shutdown conditions in automated systems. This is especially important in applications requiring coordinated machine stop sequences and controlled energy removal.

It is widely used in safety circuits that require deterministic timing behaviour for safe shutdown logic, improving system coordination and operational safety.

Typical Applications

• Industrial automation and control systems.
• Controlled machine shutdown sequencing.
• Packaging and production machinery.
• Conveyor and handling systems.
• OEM safety control panels.
• Safety interlock timing applications.
