Belden Launches LioN-Safety I/O Modules for Smarter Functional Safety
Belden has introduced its new LioN-Safety I/O modules, designed to simplify functional safety integration while improving communication between safety and non-safety automation systems in industrial environments.

Scheduled for release in late 2024, the LioN-Safety series enables manufacturers to build dedicated yet connected safety architectures without adding unnecessary complexity to existing PLC systems. The modules process signals from safety devices such as actuators, sensors, and emergency systems in real time, helping improve response speed and operational reliability.
The new platform supports both PROFIsafe and CIP Safety protocols, allowing easier integration into modern industrial automation networks. Belden states that the modules also transmit diagnostic information continuously, enabling engineers to monitor device health and verify operational readiness before critical safety events occur.

Designed for highly automated manufacturing environments, the LioN-Safety modules meet major industrial safety certifications including TÜV Rheinland SIL 3 and Category 4 requirements. The system additionally complies with Conformance Class C and Netload Class III standards.
One of the key advantages of the new modules is their ability to communicate with both safety and standard control hardware. This allows unsafe operating conditions to automatically trigger actions across connected automation systems while maintaining separation between safety functions and primary machine control logic.
Belden also integrated multiple Industrial Internet of Things (IIoT) communication protocols including OPC UA, MQTT, REST API, and CoAP. These features enable cloud connectivity for safety diagnostics, event logging, and operational reporting across industrial facilities.
The modules are ruggedized for harsh industrial environments and can be configured using dedicated PROFIsafe or CIP Safety configuration software, helping reduce deployment time for system integrators and automation engineers.

As factories continue investing in smart manufacturing and connected automation infrastructure, functional safety systems are becoming increasingly integrated with industrial networking and real-time diagnostics. Belden’s latest release reflects the growing demand for scalable safety architectures capable of supporting both operational reliability and Industry 4.0 connectivity.
