Proven and tested

Industrial safety has become an important focus topic. There is an increasing demand for safety systems. At the same time, the demands placed on such systems are increasing. In order to provide optimum protection for plant, users, goods and the environment, dangers and incidents of all kinds should be avoided. This is also evident from the increasingly strict international standards and directives.

We have specially-developed safety relays for processing safety-related signals in our product range. They can achieve a safety integrity level of up to SIL3 in accordance with EN 61508 and can therefore be used flexibly in the process industry.

Switch to safe – with Klippon® Relay

Fully reliable special relays with comprehensive certification

Klippon® Relay products ensure comprehensive operational safety. Whether large temperature ranges, strong vibrations, fast switching cycles, certain safety requirements or specific standards and directives: You can get a suitable solution for every environment.

Our product range

SIL3 Safety Relays

Functional security for process applications


Whether for a burner control system, secure emergency shut down or, for example, for pump controllers – our safety relay guarantees safe conditions and convince with superior and significant features.

Their integration into distributed control systems (DCSs) is even better, with an input filter which makes the SIL circuit immune to the test impulse which is typically used by a DCS. You will also benefit from simple maintenance: the fuses are accessible from the outside and can easily be changed. You can see the status of the safety and the monitoring devices clearly with status LED on the device. All devices are accredited though certification by the internationally recognised TÜV-NORD group – for secure process applications around the globe.

Relay modules with positively driven contacts

• Forcibly guided NC and NO contacts are designed in such a way that they cannot be closed at the same time

• If a contact of a forcibly guided contact set is welded, the antivalent contacts cannot close and the contact opening must be > 0.5 mm

• The contacts are located in contact chambers and are thus specially protected against other contacts and against the coil


Monitoring the switching states of signals in safety applications

The SAFESERIES Contact Extension ensures safe feedback to the control level. It consists of 4 different pluggable relays with matching screw sockets in the contact version 2 NO + 2 NC, 3 NO + 1 NC, 5 NO + 1 NC, 4 NO + 2 NC, and 3 NO + 3 NC. When the application is designed according to EN/ISO 13849-1, a performance level of PL "e" can be achieved. The basic component is also suitable for safety applications according to IEC/EN 62061 in order to achieve a safety integrity level of SIL3.

  • Pluggable relay modules with positively driven contacts
  • Relay with forcibly guided contacts to EN 61810-3 type A for contact multiplication of safety-related signals
  • “cULus listed” identification for high acceptance on the North American market
  • Assembled and 100% function-tested KIT consisting of the relay and socket with integrated status LED


Our TERMSERIES relay modules are predestined for secure signal monitoring in a wide range of applications. Their switching function is clearly indicated by an illuminated ejection lever, which also has an integrated marker holder. Compatibility with all accessories from the TERMSERIES allows high flexibility and easy integration into existing systems. TERMSERIES relay modules have the cULus certification required for use in the North American market.

  • Proven monitoring of signal switching status
  • 2 CO contacts with 6 A, forcibily guided according to EN 61810-3 type B
  • Positive guidance ensures a synchronous switching status at both contacts and achieves a diagnostic coverage of 99%
  • UL approval for the North American market
  • Ejection lever with integrated marker channels
