Plastics processing machines play a key role in many industries, enabling the precise and efficient production of plastic components. To improve their operation and increase efficiency, modern control systems based on solid-state relays (SSRs) are increasingly being used. Their integration into machines such as injection moulding machines, extruders or extruders brings many benefits.

Why is surge protection in DC installations crucial?

DC installations are particularly vulnerable to surges caused by lightning strikes, switching operations or other electrical disturbances, among other things. Lack of adequate protection can lead to costly repairs, downtime and safety risks, which is why surge arresters play a key role in ensuring the safety and reliability of systems such as photovoltaic panels, wind turbines or DC-powered systems. These devices are designed to redirect or absorb surge currents, preventing them from reaching sensitive equipment.

Installation contactors are extremely useful devices that are widely used in building automation, improving energy efficiency and facilitating the management of electrical systems. Thanks to them, multiple circuits can be controlled at the same time, integrated into BMS systems and the safety of installations can be increased. Find out what benefits installation contactors offer and where they can be used!

Advantages of installation contactors

There are many benefits to choosing contactors for electrical installations, including:

• Ability to control multiple circuits simultaneously - ideal for large electrical installations.
• Integration with building automation systems (BMS) - enables intelligent energy management.
• Improving energy efficiency - controlling lights and other devices according to real demand.
• Fault or mode change signalling - increases safety and comfort.

The role of latching relays

The energy transition facing businesses requires both innovation and efficient energy management. One promising solution is latching relays, which only consume energy when the state changes, as opposed to traditional relays that require continuous power supply.

The significant reduction in energy consumption in latching relays is provided by an arrangement to hold the contacts in a specific position without the need for a continuous supply of energy. As a result, latching relays only consume energy when their state changes (on/off, off/on).

Are you looking for a compact and reliable way to control electrical circuits? Is limited space in your switchgear a challenge you often face? Although the RG25 relay is a solution that not only saves space, but also ensures stable and efficient operation of your electrical systems. Find out why this product is so versatile and appreciated in many industries.

In times of growing interest in renewable energy and the need to manage it efficiently, the protection of such installations from damage is becoming a very important factor. The provision of equipment to support the development of photovoltaic and wind farms, enabling efficient energy management, infrastructure protection and reliability in harsh environmental conditions is the basis of today's installations. It therefore becomes indispensable to use components such as energy meters, high-current industrial relays or surge arresters, which are perfectly suited to commercial and industrial applications, guaranteeing safety, precision and reliability.

Miniature relays are a key component of many electronic, automation systems, especially where space saving or signal control is of paramount importance. However, selecting the right relay for a particular application is a process that requires consideration of many factors that determine the reliability and efficiency of the overall system. In this material, we will discuss what to look for when selecting miniature relays to ensure optimal system performance

Combining the power of electricity consumption meters and astronomical clocks. How to do it?

Time relays are used to automate power control in electrical installations. Learn about their construction, principle of operation and types!

The RPN series monitoring relays offered by Relpol are excellent elements protecting the motor against failure, with which we can reliably monitor the current, voltage and temperature of the motor.

Process automation requires the use of more and more electric motors. Currently, they are used in every area of life: in production systems, transport, air conditioning and ventilation systems, and more and more often in buildings.

Construction of modern and complex industrial automation systems often requires the use of multiple relay modules of different types in a single control cabinet. Relays used in large numbers in such applications are usually multi-pole versions, which results in the need to make a huge number of cable connections in the relay sockets during installation work. For this reason, each improvement in the design of the sockets and the relays used bring measurable benefits, both in design and during installation and daily operation. The new product line of interface relays from Relpol S.A. using push-in terminal sockets has been designed with attention to the smallest details to improve the work of engineers, speed up the work of electricians and people operating the installation during its operation.
