Functional safety in the mining industry

Functional safety in the mining industry Safe switch-on and switch-off

Adhering to safety guidelines is of the utmost importance in the mining industry. The implementation of safety standards requires consistent and efficient solutions. The safety portfolio from Phoenix Contact meets these requirements. The products for functional safety are characterized by their easy installation and configuration. From safe coupling relays to safe controllers, you’ll always find the right logic module for your standard-compliant and efficient solution in our portfolio.

Products for functional safety


Highly compact safe coupling relays

Highly compact safe coupling relays

With an overall width starting at 6 mm, PSRmini relays are extremely narrow SIL-certified coupling relays for safe switch-on and switch-off. Force-guided contacts enable quick and easy diagnostics. The diagnostic LEDs enable SIL3-qualified inspections to be performed directly on the module. Active error feedback to the controller ensures short downtimes during planned maintenance phases.

Conventional safe coupling relays

Conventional safe coupling relays

The PSRclassic series includes conventional coupling relays with force-guided contacts for safe switch-off. The conventional coupling relays are characterized by a wide range of functions and versions. They are compatible with common safe systems. With a housing width starting from 17.5 mm, they correspond with market-standard housing dimensions and feature approvals for all global markets.

Safe I/Os with SafetyBridge Technology

Safe I/Os with SafetyBridge Technology

With the Inline and Axioline F I/O systems, safety is integrated into a network – without using a safety controller. The logic module with SafetyBridge Technology monitors the safety-related communication between the I/O modules distributed throughout the network. I/O extension modules acquire the safety signals and output them wherever they are required.

PSRmodular configurable safety system with application example

Customized safety solutions

The configurable PSRmodular safety system from Phoenix Contact enables you to adapt your safety technology individually to your specific needs. It makes it possible to cost-effectively implement small applications with three safety functions as well as applications with up to 160 I/Os. In addition to monitoring classic safety functions, such as emergency stop signals, safety door locks, light grids, and safety shut-off mats, you can also implement safety functions such as speed, zero-speed, or direction of rotation, and safe analog value monitoring. The system is suitable for machines and process applications up to PL e or SIL 3.
