6-mm safe coupling relays


Phoenix Contact creates world’s slimmest safety relay approved for hazardous location

Middletown, Pa. – Phoenix Contact’s new PSRmini family includes 6- and 12-mm safety relays that meet the strict safety requirements of the process industry, including hazardous location approvals. With a footprint that is 70 percent smaller than standard 22.5-mm safety relays, the PSRmini is the narrowest SIL-certified coupling relay available on the market.

The 6-mm devices (PSR-PS) and 12-mm modules (PSR-PC) can be used as output elements for potential-free coupling to safety-related controllers. The PSRmini range includes SIL-certified modules for safe deactivation (e.g., emergency shutdown) and safe activation (fire and gas). Thanks to the safety relays’ internal logic, the fail-safe PLC does not require any feedback to the safety-related inputs.
