Why Choose the Pizzato CSME-20VU24-TF1 Expansion Safety Module?
The Pizzato CSME-20VU24-TF1 is a specialised safety expansion module with delayed output functionality, designed to extend the capabilities of industrial safety systems. As part of the advanced Pizzato CS ME series, it provides additional safety outputs combined with controlled delay behaviour for enhanced machine protection.
This module features delayed de-energising outputs (TF1 function), allowing controlled shutdown sequences in safety-critical applications. This ensures that machinery components stop in a predictable and safe manner, reducing risk during emergency stops or fault conditions.
Operating on a 24 V DC supply, the CSME-20VU24-TF1 includes 4 normally open (NO) safety contacts and 2 normally closed (NC) contacts, along with an integrated feedback contact. Its DIN rail mounting design ensures easy integration into industrial control panels and automation systems.
Key Advantages
- Expansion module for safety systems, increasing output capacity.
- Delayed de-energising function (TF1) for controlled shutdown.
- 4 NO + 2 NC contact configuration for flexible safety circuits.
- 24 V DC operation suitable for industrial control systems.
- Integrated feedback circuit for monitoring and diagnostics.
- Improves safety performance in emergency stop and fault scenarios.
Key Features
- Pizzato CS ME series expansion module.
- Delayed output contacts at de-energising (TF1).
- 4 NO safety contacts + 2 NC contacts + 1 NC feedback.
- Supports single or dual-channel safety control systems.
- Screw terminal connections for secure wiring.
- DIN rail mounting for control panels.
Controlled Safety Shutdown for Industrial Machinery
Modules such as the Pizzato CSME-20VU24-TF1 are essential in applications where a controlled stop is required. The delayed de-energising function ensures that outputs remain active for a defined period after a stop command, allowing machinery to come to a safe halt without abrupt interruption.
This functionality is particularly important in systems with inertia, such as conveyors, rotating machinery or automated production lines, where immediate shutdown could cause mechanical stress or safety risks.
Typical Applications
- Safety circuits requiring delayed shutdown sequences.
- Industrial conveyors and material handling systems.
- Machine guarding and emergency stop systems.
- Packaging and processing machinery.
- Automation systems with controlled stop requirements.
- OEM machinery and control panel design.
