SFX programmable safety controller

The Eaton SFX programmable safety controller is an IEC 61508 safety integrity level (SIL) 2 certified controller designed for stationary and mobile embedded hydraulics system applications. With a rugged mechanical design and unique functional safety features, SFX controllers enable you to develop and certify functionally safe platforms quickly and cost efficiently.

The partitioned safety-application development environment provides greater flexibility

Unlike other embedded controllers, the SFX programmable safety controller partitions safety-control application functions through a dual-processor architecture, enabling changes to control applications without having an impact on safety function certification. Physical separation of the pre-certified safety and control application domains minimises the effort to design and integrate new features as well as the time and expense associated with safety certification.

Pre-certification and software configurability helps ease development

The SFX programmable safety controller is IEC 61508 pre-certified SIL 2 to help simplify certification of work, steering and propelling safety functions. Need customised functionality? The controller provides white space for customised safety functions that can be independently certified, while configurable I/O enables maximum machine-application flexibility. Plus, a rich library of C-API functions facilitates application software development.

Extreme durability ensures reliable performance

With an industry-proven mechanical enclosure, the SFX programmable safety controller is built to last. The controller features a best-in-class temperature rating of up to 105 °C and a market-leading environmental rating of IP67 and IP69K, giving you a wider range of machine installation options plus reliable performance in rugged applications.
