Tips: Difference between signal relay and power relay

Signal relay is usually used for monitoring and protection. It is widely used in the secondary protection circuit of distribution high voltage cabinet. For example, If the transformer oil temperature is over 85 degrees and A normally open contact is closed on the temperature monitor indicator, making the contact string in signal relay coil back to the road, so there are signals leads to relay coil absorption and action and high voltage switch is off at the same time to remove the station transformer load, so as to protect the transformer. However, there are many kinds of signal relays, some of which are directly buzzing or flashing as alarm signals.
Power relay is a device that can produce step in one or more electrical output circuits when the input (or excitation) satisfies some specified conditions. It can be used in the neutral point directly grounded system as the direction element of zero sequence current protection.

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.
