With its new “SCS 24V DC SIL3” SAFESERIES safety relay Weidmüller offers a module designed to shut down process industry plant and plant components in the event of an emergency. TUV NORD certified the safety relay fulfils SIL3 requirements in accordance with EN 61508.
The relay features a safety and an additional monitoring circuit. Three relays are connected in series in the safety circuit to guarantee safe isolation of the output circuit at all times. The typical break time is 14 and the make time 7 ms. An internal 5 A fuse guarantees short-circuit protection in the SIL circuit.
A special circuit arrangement in the input circuit ensures the module is immune to test pulses, which are generally undertaken in circuitry of this kind. The additional monitoring circuit is designed as a wide voltage input. The typical make time in the monitoring circuit is 21 ms. These design features in a single device provide safety-oriented shutdown functionality (SIL3) as well as electrically isolated 24-230 V AC/DC field signals to the higher-level controls.
Features that allow the user to deploy the relay to suit individual requirements, such as in back-up systems with high DC voltages or overfill protection solutions for tank systems. Two yellow LEDs integrated in the safety and monitoring circuits are located on the front of the device to simplify relay function and fault analysis. Easy accessibility ensures users are able to replace the fuse on site. Measuring just 113.6 mm x 22.5 mm x 117.2 mm (length/width/height) the safety relay is compact by design, meaning it requires only little space on DIN TS35 mounting rails in the electrical cabinet. Screw connection technology ensures vibration-resistant connection of conductors with cross-sections between 0.14-2.5 mm².

About us
Be it automobile manufacturing, electricity production or water management - hardly any of today’s industries can do without electronics and electrical connectivity. In this internationalised, technologically changing world, the complexity of requirements is rapidly increasing due to the emergence of new markets. New, more varied challenges have to be overcome, and the solutions to them will not be found in high-tech products alone. Connectivity is the key, whether it involves power, signals and data, demands and solutions or theory and practice. Industrial Connectivity needs connections. And that’s precisely what we stand for.
Our Industries
Our industrial environment is full of connections that need to be connected, controlled and optimised. We are absolutely committed to always providing the best connection possible. This is not only demonstrated in our products but also in the human connections we maintain: We develop solutions in close cooperation with our customers which meet the full measure of all requirements of their particular industrial environment.
Industry 4.0 and Digitalisation
In the light of Industry 4.0, customised, highly flexible and self-controlling production units often still seem to be a vision of the future. As a progressive thinker and trailblazer, Weidmüller already offers concrete solutions that allow producing companies to prepare themselves for the “Industrial Internet of Things” and for safe production control from the Cloud - without the need to modernise their entire range of machinery.
