Safe coupling relay with force-guided contacts, 2 changeover contacts, 1-channel, fixed screw terminal block, width: 17.5 mm
Our TÜV-certified SIL coupling relays for safe switch-on and switch-off enable the electrical isolation of signals up to SIL 3. System downtimes can be reduced to a minimum by diagnostic functions, such as integrated proof test and line load monitoring. The SIL 3 coupling relays with ATEX, G3 coating, and temperature range up to 70°C are suitable for special applications in the process industry.More information
Applications in the process industry are fundamentally different from those in the manufacturing industry. As such, safety technology must meet different requirements in this industry.
Safe coupling relays are often used in process technology systems; they electrically isolate and amplify the power of electrical signals for functional safety. Phoenix Contact has developed SIL-certified coupling relays to meet the demands of process technology applications.
Phoenix Contact has force-guided coupling relays and safe force-guided coupling relays in its portfolio. Forced guidance uses mechanical means to prevent N/O and N/C contacts from closing at the same time. This technology therefore provides the highest level of functional safety.
The safe coupling relays are also SIL-certified. SIL, or safety integrity level, is a method for assessing a system’s reliability. Levels SIL 1, SIL 2, and SIL 3 must always be viewed in relation to the hazard.
If you choose our SIL-certified coupling relay, you will not need to conduct an assessment. The SIL coupling relays have been tested and certified by an independent institute. All safety-related characteristics are therefore available. You can also carry out comprehensive diagnostics with an integrated test pulse filter.
The Phoenix Contact product portfolio features SIL-certified coupling relays for safe switch-on (also known as fire and gas or energized to safe) and for safe shutdown (emergency shutdown or de-energized). Our safe coupling relays meet the specific demands of the process industry – including for use in potentially explosive areas.
Choose between the highly compact PSRmini product family and the conventional PSRclassic product range in a market-standard design.
With an overall width starting from 6 mm, PSRmini relays are the narrowest SIL coupling relays on the market.
In the PSRclassic series, you will find SIL coupling relays for safe switch-off. The conventional coupling relays are characterized by a wide range of functions and versions. The housing width corresponds to the market standard.
The safe coupling relays are tailored to control systems in the process industry.
These include the following safety instrumented systems (SIS):
The force-guided contacts enable quick and easy diagnostics. This ensures short downtimes during scheduled maintenance phases.
Easy proof test
The Termination Carriers are designed to accommodate the PSRmini and PSRclassic. With the module carriers, you can reduce your wiring effort and speed up installation.
Thanks to the consistent concept and special system technology, Termination Carriers help you prevent wiring faults, which would otherwise result in expensive and time-consuming troubleshooting. We will be happy to adapt the Termination Carriers to suit your specific requirements.
