Inline - safe I/Os

Our safety-related I/O terminals also underline the flexibility of the Inline I/O system. Depending on the bus couplers and safety controllers, the I/O terminals can be used with PROFIsafe in PROFINET and PROFIBUS systems or in INTERBUS Safety applications.

We offer digital input and output modules as well as relay modules. These products enable you to meet safety requirements up to:

• PL e (EN ISO 13849-1)
• SIL 3 (IEC 61508)
• SILCL 3 (EN 62061)

Safety without a safety controller
Do you want to integrate functional safety, independent of the network, without additional safety controllers? Then choose safe I/Os with SafetyBridge Technology.

The highlight is distributing the yellow, safe I/Os as required in your system. The modules work centrally or peripherally using a standard control system.

SafetyBridge Technology means that input and output modules exchange safety-related signals with each other. Since the modules process the safety functions themselves, they use the standard controller and network only for transport purposes.

Without a safety controller or safe fieldbus system, this is a cost-effective solution for functional safety in standard applications.

The safe I/O modules with SafetyBridge Technology meet all safety requirements up to SIL 3 or PL e.

Deactivate connected standard output terminals safely with the safe Inline ECO Safe I/O terminal. All status and error messages are forwarded to the standard controller, making the safety solution transparent. This reduces safety-related downtime.

Integrate the safe I/O terminal by simply plugging it into your Inline I/O station. The standard output terminals are then mounted to the right of the safe I/O terminal.

When a sensor is activated, e.g., emergency switching off, the actuator voltage supply for the connected standard output modules is shut down for safety reasons. Up to two dual-channel sensor circuits can be connected to one safe I/O terminal. If you need more sensor circuits in your application, you can integrate additional safe I/O terminals.

Depending on the sensors and actuators used, you can implement safety functions up to SILCL 3 and PL e.
