Safety Relay provides multifunctional operation.
Press Release Summary:
Measuring 22.5 mm, Model PSR-MXF accepts up to 3 dual-channel safety sensors: 2 local, independent sensor circuits as well as overriding safety circuit useful for simultaneous shutdown. Unit is rated for high levels of safety, including SIL 3, Category 4, and PLe. Since relay depends on wire only configurations, it requires zero software or turnstile configurations. Device is available in 4 different types of connection technology, including push-in technology.
Original Press Release:
PSR-MXF Multifunctional Safety Relay
Middletown, Pa. – The PSR-MXF multifunctional safety relay is the newest addition to the Phoenix Contact PSR safety relay line. This relay can help small and medium machine builders reduce cost and save space. The PSR-MXF accepts up to three dual-channel safety sensors: two local, independent sensor circuits, as well as an overriding safety circuit useful for simultaneous shutdown. With this safety circuit, one safety relay can do a job that would otherwise require three safety relays or a configurable safety relay.
The PSR-MXF closes the gap between two traditional types of safety solutions. For example, some engineers achieve emergency shutdown by wiring several safety sensors in-series into a single relay. Though this design is inexpensive and simple, it results in a loss of diagnostic capabilities and can mask critical safety faults in the system. A more comprehensive solution is to individually wire sensors to relays or to use configurable safety systems; however, conventional safety relays are often expensive, and configurable systems are often over-dimensioned. With the PSR-MXF, engineers achieve the advanced safety capabilities at a competitive price point.
At a compact size of 22.5 mm, the PSR-MXF is rated for the highest levels of safety: SIL 3, Category 4 and PLe. Also, the PSR-MXF requires zero software or turnstile configurations, as it depends on simplified, wire only configurations. The relay is available in four different types of connection technology, including push-in technology.
