Why Choose the Pizzato CS ME-20XU24-TF2 Safety Expansion Module?
The Pizzato CS ME-20XU24-TF2 is a compact and highly reliable safety expansion module with delayed de-energising outputs designed to increase the number of relay contacts available within compatible industrial machine safety systems. As part of the Pizzato CS ME-20 series, it provides additional safety and signalling contacts while maintaining the high safety performance required in demanding automation applications.
The module provides 4 NO safety contacts, 2 NC auxiliary signalling contacts and 1 NC feedback contact, with its outputs delayed when the module is de-energised. Forcibly guided relay contacts and support for one- or two-channel control make the CS ME-20XU24-TF2 suitable for integration into appropriately designed safety architectures up to SIL 3 and PL e.
The TF2 variant provides a fixed 2 s release delay, allowing a controlled period before the relay outputs change state following removal of power. Operating from a 24 V DC supply and equipped with a connector with spring terminals, the CS ME-20XU24-TF2 provides efficient installation and dependable delayed safety switching within industrial control panels.

Reliable Delayed Safety Expansion for Industrial Machinery
Safety expansion modules such as the Pizzato CS ME-20XU24-TF2 allow additional safety-rated relay contacts to be incorporated into machinery safety circuits without changing the fundamental monitoring function of the associated safety controller or base module. Forcibly guided contacts and the dedicated feedback contact support reliable monitoring of the expansion relay within appropriately designed safety architectures.
The TF2 version introduces a fixed 2 s delay at de-energisation. This controlled delay is useful in machinery where selected safety outputs must remain active briefly during a controlled stopping sequence before power is removed from associated actuators, contactors or other machine functions.
Typical Applications
- Expansion of industrial machine safety relay outputs.
- Controlled delayed machine shutdown sequences.
- Guard locking and machine access safety systems.
- Emergency-stop safety architectures requiring additional contacts.
- Production and processing machinery.
- OEM automation and machine safety control panels.
