Why Choose the Pizzato CS ME-20XU24-TF1 Safety Expansion Module?
The Pizzato CS ME-20XU24-TF1 is a compact and highly reliable safety expansion module with delayed de-energising outputs designed to increase the number of safety contacts available from a compatible base safety module. As part of the Pizzato CS ME-20 series, it is suitable for machinery safety systems requiring additional positively guided relay outputs with a controlled shutdown delay.
The module provides 4 NO safety contacts, 2 NC signalling contacts and 1 NC feedback contact, with the outputs delayed when the module is de-energised. It can be controlled using one or two channels and supports safety applications up to SIL 3 and PL e, with the achievable safety category dependent on the associated base safety module and overall system architecture.
The TF1 version provides a fixed 1 s release delay, while the X connection variant uses a connector with spring terminals for efficient control-panel wiring. Operating from a 24 V DC supply, the CS ME-20XU24-TF1 is well suited to machine guarding, emergency-stop and other safety circuits where additional delayed contacts are required.

Reliable Delayed Safety Expansion for Industrial Machinery
Safety expansion modules such as the Pizzato CS ME-20XU24-TF1 allow additional safety contacts to be incorporated into machinery safety circuits without changing the fundamental function of the associated base safety module. Its forcibly guided relay contacts and feedback connection support dependable monitoring within appropriately designed safety architectures.
The TF1 variant introduces a fixed 1 s delay during de-energisation. This controlled delay can be useful where machinery requires a defined shutdown sequence before safety contacts change state, while the combination of four NO safety contacts and auxiliary NC contacts provides flexibility for switching and status signalling.
Typical Applications
- Expansion of industrial machine safety relay outputs.
- Controlled delayed machine shutdown sequences.
- Emergency-stop safety systems.
- Machine guard and access protection circuits.
- Production and processing machinery.
- OEM automation and machine safety control panels.
