Siemens safety relay with communication and simulation capability
For years, Siemens has been making it easy to implement local safety applications quickly and efficiently - with SIRIUS 3SK. The 3SK safety relays offer maximum functionality while saving space in the control cabinet.
Highlights
SIRIUS 3SK2 with Profinet
- Seamless integration of safety applications at automation level
- Parameterisation and diagnosis from any location with Safety ES
- Installation information on all devices, such as smartphones
SIRIUS 3SK2 with SIRIUS SIM
- Offline simulation of applications - finds the right component
- Create configurations and test without physical components!
Communication
The flexible, modular series of safety relays can be optionally extended with a Profinet communication module. This helps users seamlessly integrate safety applications into their automation systems. With the SIRIUS 3SK2 safety relay, you can easily configure multiple safety functions in one compact product. With the user-friendly drag & drop parameterisation software Safety ES, you can easily design and test safety functions and optionally simulate your design using SIRIUS SIM or diagnose the application.
This opens up new possibilities without extensive wiring or programming. Profinet provides remote access to parameter settings and extensive diagnostic functions. This greatly simplifies commissioning and diagnosis, reducing or even eliminating downtimes. Machine operators can quickly access the specific factory information they need on the HMI or smartphone.
Simulation
Many machine builders are faced with the need to quickly and easily find the right component for their application. The free SIRIUS SIM 3SK2 simulator software gives users the chance to familiarise themselves with the wide range of functions in 3SK2 based on existing applications. Configurations can also be created and tested in the simulator. The ability to create and test configurations quickly and easily saves time and money during the engineering phase, as no physical components are required for simulation and applications can be modified with great ease and in a short time.
TIA Portal and Safety ES
Safety ES software can be integrated into TIA Portal in addition to the usual standalone use. This provides you with a unique combination between SIMATIC PLC control and 3SK2 safety relays.
Hardware
The 22.5mm SIRIUS 3SK2 is the narrowest software parameterisable safety relay on the market. It has 10 safe inputs, 2 safe and 1 signal outputs. This is sufficient to realise 3 to 4 safety functions directly with one module. With the 45 mm wide 3SK2 version, which has 20 safe inputs, 4 safe- and 2 signal outputs, you can even realise 6 to 8 safety functions. This version has a diagnostic display. The outputs of the 3SK2 can be independently assigned and controlled.
Applications
Typical applications for SIRIUS 3SK2 are emergency stop circuits, access (gate) monitoring, area monitoring and muting with light curtain or laser scanner. Additional safety applications can easily be realised according to your requirements.
Easy to combine
Like the SIRIUS 3SK1 safety relay, the SIRIUS 3SK2 is easy to combine via connection adapters with 3SK1 output expansion modules and SIRIUS 3RM1 failsafe motor starters - even without additional wiring!
The SIRIUS 3SK safety relays can be seamlessly integrated into machine automation. This minimises the engineering and training impact and has a positive impact on system availability. Flexibility is guaranteed thanks to the modular design and user-friendly software interface of the 3SK safety relays.

Siemens - SINAMICS G220 variable speed drive now also in IP55Read moreIn addition to the previously released IP20 variant of the SINAMICS G220 variable speed drive, the IP55 version of this innovative drive is now also available. This version comes standard with coated circuit boards that make the inverter resistant even outside the control cabinet to aggressive influences in a harsh industrial environment. As an option, a housing-mounted isolating switch can also be supplied to ensure safe disconnection of voltage without any other external components.

DigiFlow - Making Life Easier for CustomersRead moreTechnical services provider Breemes supplies customers with PLCs, drives and other materials. Customers like industrial automation company Digi-Flow. Turnover, both parties feel, is not the ultimate indicator of a good relationship. Coming up with solutions together and providing knowledge are equally important. Ultimately, Breemes has to make the customer’s life easier, Digi-Flow CEO Eric Decant believes. Antwerp-based Digi-Flow assists industrial companies in their transformation to smart industrial environments using industrial automation and digitalisation. The company is a spin-off from ESAS Automation in 2020. Solindus, now ESAS, had grown into a company with 2,000 employees after its founding in 2003 by Eric and Robert Decant. With Digi-Flow, they wanted to go back to small-scale entrepreneurship. Eric Decant is now the CEO of the company, which has 30-plus employees. ‘I’m still ambitious, but I don’t want to complete this kind of strenuous trajectory on such a large scale anymore.’ Meanwhile, he is grooming his son to take over the reins. This makes Digi-Flow a true family business, as reflected in its core values of co-creation, long-term vision, lifelong growth and personal.

ATR Engineering - Short delivery times for components and decisionsRead moreBeing able to shift gears quickly is crucial to the success of industrial automation projects. This refers not only to the delivery of components but also to decision-making. Short lines of communication are important here. That was the case in the project to control a washing line for plastic PET flakes, in which ATR Engineering and itsme teamed up closely. ‘The added value of our collaboration is being able to anticipate customer requests extremely quickly.’ Bringing ten years of experience in industrial automation to the table, Adrie van Triest started his own company in 2019. With a broad approach, ATR Engineering in Berkel-Enschot focuses on hardware and software engineering. ‘Our area of expertise is offering total solutions for industrial automation centred around the design of PLC controls. We will sit down with a customer to discuss pending automation issues and we will determine the needs and wishes for a project together in advance. We also offer flexible support for projects or commissioning.’ ATR Engineering is a small company currently employing four engineers from different disciplines. There is also a permanent ‘flexible shell’ of engineers and technicians available to help during peak periods.

Top Cold Control - Short lines for energy management and project collaborationRead moreSpecialist in industrial refrigeration Top Cold Control carries out complete projects, and energy management cannot be missing from that these days. This starts with a lot of measuring. For a cold store in Amsterdam, itsme, in consultation with Top Cold Control and the customer, designed a solution to integrate energy measurement in the control system. Top Cold Control from Nieuwkuijk, specialised in industrial refrigeration technology, realises large projects for customers in the Netherlands, Belgium, Germany and, through them, elsewhere in the world. These include refrigeration and freezer systems for slaughterhouses, processing companies, cold stores and transport companies. Top Cold Control can handle all common refrigerants, but specialises in the use of the natural refrigerants ammonia (NH3) and carbon dioxide (CO2). For fast freezing, Top Cold Control supplies advanced, energy-efficient freezing tunnels. "The company stands out for its short lines of communication," says operations manager Arjan Maas. "We are always accessible and customers immediately get the right person on the line with us."

Dymotec - Open Lines in a ‘Perfect Storm’Read moreCOVID-19 and global component scarcity threw the industry into a ‘perfect storm’. Industrial automator Dymotec and Breemes kept the phone lines constantly open to tackle the scarcity problem together with creativity and proactivity. Dymotec in Olen (B) focuses on industrial automation spanning a broad spectrum of industries, from food and pharma to logistics and metal. The company has been around for 30 years and joined the Jeco Energies Group in 2022. Dymotec now has some 50 employees and also has a flexible shell with technicians, programmers and project engineers. Ever since its establishment, the company from Kempen has had a relationship with (the predecessors of) Breemes.
