Monitoring relays

Control relays - essential elements of modern electrical installations

Control relays are key components of electrical systems.   They ensure the safety and reliability of devices and entire installations . At Onninen we offer a wide selection of these products. Our range includes leading brands such as F&F, Zamel, Relpol, Eaton and Eti. We provide solutions for a variety of industrial and commercial applications.

Control relays monitor electrical parameters. They respond to irregularities in the network operation. They protect connected devices from damage. Our offer includes:

• Voltage asymmetry sensors
• Phase sequence sensors
• Phase loss sensors
• Automatic phase switches
• Fluid level control relays
• Voltage and monitoring relays

Each of these products has a specific protective function.   Selecting the right relay is key to ensuring trouble-free operation of the installation . Our experienced specialists will be happy to advise you on choosing the optimal solution.

Applications of control relays in modern installations

Control relays are used in many industries. They are found in industry, construction and infrastructure. For example, in factories they protect production lines from the effects of power failures. In office buildings they protect air conditioning and ventilation systems. In sewage treatment plants they control the operation of pumps and mixers.

We recently completed a project for a large logistics center. We used Eaton control relays there. They protect the operation of internal transport systems. They detect voltage asymmetry and phase loss. They prevent damage to expensive equipment.   Thanks to this, the center operates continuously, without costly downtime .

In the case of modernization of older installations, control relays are a must-have. They improve the safety and reliability of the entire system. We often come across the question about the possibility of such modernization. We always recommend consulting our specialists. They will help you choose the optimal solutions.

Key parameters when selecting control relays

Selecting the right control relay requires taking into account many factors. The most important are:

• Type of monitored parameter (voltage, current, temperature)
• Measurement range
• Measurement accuracy
• Response time
• Type and number of outputs
• Configurable
• Environmental working conditions

At Onninen we offer control relays tailored to various requirements . Our products are characterized by high quality and reliability. They provide effective protection even in difficult industrial conditions.

Many customers ask us about the differences between the individual models. For example, digital asymmetry sensors offer greater measurement precision. They allow for more precise setting of the activation thresholds. In turn, potential-free relay modules are suitable for applications requiring galvanic separation of circuits.

In our daily practice, we see a growing interest in intelligent relays. They enable remote monitoring and configuration. They are perfect for distributed industrial installations. They allow for a quick response in the event of anomalies.

Innovations in the field of control relays

The control relay industry is constantly evolving. New technologies and solutions are emerging. At Onninen, we follow these trends. We provide our customers with state-of-the-art products.

One of the interesting trends are relays with a self-diagnostic function. They monitor their own efficiency. They signal potential problems with operation. This is the next level of protection for electrical installations.

Another innovation is relays with digital communication. They enable integration with building automation systems. They allow for central management of electrical safety of the entire facility.

At Onninen we focus on innovative solutions . We offer products using the latest technologies. At the same time, we provide full technical support. We help in the selection, configuration and start-up of control relays.

Our experience shows that investment in advanced relays pays off quickly. They prevent costly failures. They increase the energy efficiency of the installation. They contribute to lower operating costs.

In case of doubts regarding the selection of control relays, we encourage you to contact us. Our specialists will be happy to answer your questions. They will help you choose the optimal solutions. Together we will take care of the safety and reliability of your electrical installations.
