Original Press Release:

Safety Relays for Process Applications

Harrisburg, PA - Phoenix Contact now offers PSR safety relay modules specially designed for process applications with optimized startup behavior approved to SIL3 / IEC 61508. Until now, conventional safety relay modules have had a very high startup current that the control system interprets as a short circuit. The PSR modules provide two safely isolated redundant normally open contacts and one normally closed contact that can switch up to 250 V AC / 6 A in a 22.5 mm housing.

These compact safety relays are used to electrically isolate field applications from the control system or to adjust the voltage or power. In addition to being used in safety-oriented control systems, these relays form an integral part of the safety chain for electrical and electronic applications in process technology and mechanical engineering.

Phoenix Contact Inc. Quality System is registered to ISO 9001: 2000-Quality Systems Model for Quality Assurance in design, development, production, installation and servicing.

Information on Safety Relays is available from Phoenix Contact Inc., Technical Service Department, (800) 322-3225; E-mail: [email protected].
