The coupling relays with force-guided contacts from Phoenix Contact are basic devices for single-channel control. The coupling relays can be used for electrical isolation, power amplification, and increasing the number of contacts.

Your advantages

  • Maximum safety with force-guided contacts in accordance with EN 50205
  • Reliable signal exchange between two systems with feedback function

Force-guided coupling relays for universal use

Signal exchange with feedback function  

Signal exchange with feedback function

The force-guided coupling relays are suitable for single-channel control and enable safe diagnostics via a force-guided N/C contact.

They ensure, for example, reliable signal exchange between two systems with a feedback function.

You can therefore implement applications that are to be designed in accordance with DIN EN 50205 Type A (circuit with 1 N/O contact / 1 N/C contact). You will also benefit from cULus-listed approval for UL 508 industrial control equipment. With this approval, you and your customers are on the safe side in the North American market. The integrated status LED allows you to determine switching states at any time.

The force-guided coupling relays are available in the PLC-INTERFACE and RIFLINE complete product families.

Safety through force-guided contacts

Force-guided contacts  

Force-guided contacts for the highest level of safety

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 people and machinery.

Further safe, SIL-certified coupling relays

Safe, SIL-certified PSRmini coupling relays  

Safe, SIL-certified coupling relays for safe switch on and off

The safe coupling relays with force-guided contacts are SIL-certified and are used for electrical isolation and power amplification.

You can choose the PSRclassic safe coupling relays, the standard version on the market, or the highly compact PSRmini safe coupling relays. At 6 and 12 mm, these coupling relays are the narrowest on the market.
