Safety I/O modules
17 October 2024
SUPPLIER OF network infrastructure and digitisation solutions, Belden, has announced the expansion of the Lumberg Automation LioN family with its new LioN-Safety I/O Modules. Designed to support functional safety efforts in industrial operations, the modules streamline the transmission of safety and non-safety-related data over existing networks.

The new LioN-Safety I/O Modules support the PROFIsafe and CIP Safety protocol, with the latter expected to be available in the fourth quarter of 2024, and give manufacturers a compact, ruggedized product uniquely designed to support the real-time data transmission required in highly automated operations. The safety solution from Belden enables the exchange of safety-relevant data and diagnostic information through existing network connections, saving valuable time, resources and space.
With the LioN-Safety I/O Modules, users benefit from:
Easy integration: Protect workers and machines by integrating modules into a PLC’s engineering tools with PROFIsafe or CIP Safety via standardized device description files that transmit safety data and diagnostics.
Maximum flexibility: Connect safety inputs/outputs, non-safety I/Os and IO-Link signals – and communicate with the cloud – for added versatility and functionality.
High performing, safe operations: Use PROFINET/PROFIsafe I/O modules in applications with conformance class C and Netload class III or CIP Safety, and benefit from TÜV Rheinland-certification up to SIL 3, Cat 4 and Performance Level e (PLe).
“As industrial automation increases, the challenge – and urgency – to ensure the safety of plant workers becomes more critical,” said Jeremy Friedmar, director of product management, data ingestion and firewalls. “LioN-Safety I/O Modules streamline the transmission of essential safety and diagnostic information – from machine-to-machine and machine-to-human – to protect workers, as well as the machines themselves, and the overall plant environment.”
Designed with a space-saving, compact metal housing, LioN-Safety I/O Modules ensure durability and reliability even in the harsh environments of automotive manufacturing, consumer packaged goods, machine building, metals and logistics.
