With its PSR-ETP coupling relay, Phoenix Contact is offering a power adaptation module with electrical isolation specifically designed to address the requirements of the process industry. This is because, in addition to safety-related interruption of circuits, safe switch-on is becoming increasingly more important. The relay is certified according to SIL3.
The integrated test pulse filter and the adapted current control circuit guarantee a long service life and ensure that the relay is compatible with the different safety-related systems.
The optional line/load monitoring feature supports load-dependent configuration and allows unified diagnostics from the control system to the actuator. The existing wiring is used to signal a wire breakage or loads that are missing or incorrect. This means that additional installation costs and additional digital inputs to read back the actuator state can be eliminated.
Phoenix Contact, founded over 80 years ago, is a leading manufacturer of electric connection and industrial automation technology. 11,000 employees, 47 own sales companies and 30 sales partner worldwide ensure customer proximity.
