Wiring diagram

Tips: Function of SSR

A Solid State Relay (SSR) functions as an electronic switch that uses semiconductor components to control the flow of electrical current. Unlike traditional electromechanical relays, SSRs have no moving parts. When a small control voltage is applied to the input, the semiconductor components (such as thyristors, triacs, or transistors) are activated, allowing the current to flow through the output circuit. This results in fast, reliable, and silent switching.

Solid state relays are commonly used in applications where high durability and performance are essential. These include industrial automation, heating control, motor control, and lighting systems. Their ability to handle high-frequency switching without mechanical wear, along with resistance to shock and vibration, makes them ideal for demanding and harsh environments. SSRs also offer advantages such as compact size, no sparking, and low control power requirements, making them suitable for a wide range of modern electrical and electronic applications.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
