- Simple verification possible, as all safety-relevant characteristic data is available
PSRmini highly compact safe coupling relays
Thanks to the relay technology developed in-house, the PSRmini coupling relays are extremely space-saving. The SIL coupling relays with force-guided contacts provide a huge space-saving potential of up to 70% with full performance.
- Overall width from 6 mm
- Coupling relays for safe startup and safe shutdown
- LEDs enable SIL-qualified diagnostics directly on the module
- Active error messaging to the controller ensures short downtimes during planned maintenance phases
- Compatible with standard safe systems
PSRclassic classic safe coupling relays
In the PSRclassic series, you will find the classic coupling relays with force-guided contacts for safe shutdown. The classic coupling relays are characterized by a wide range of features and versions. The housing width is suitable for the market-standard housing dimensions.
- Overall width from 17.5 mm
- Coupling relays for safe shutdown
- Compatible with standard safe systems
Proven safety thanks to force-guided contacts
The N/O and N/C contacts of an elementary relay are connected to one another mechanically through forced guidance. This prevents N/O and N/C contacts from closing at the same time. In conjunction with a suitable circuit, failure to open can be reliably detected. This is the most reliable way to ensure maximum safety for both person and machine.
In order to provide a high level of safety, our PSRmini and PSRclassic products are equipped with force-guided contacts.
Flexible I/O marshalling system
Smart I/O, i.e., universal I/O modules, offer brand new possibilities for users in the process industry, both for new plants and for retrofits.
The flexible I/O marshalling system from Phoenix Contact helps to make Universal I/Os on the interface and marshalling level truly “universal”. The system combines a standardized base module and replaceable input/output accessories (IOAs) with various electrical functions.
