Tips: What is external powered signal isolator and loop powered signal isolator?

External powered signal isolator
It need an independent DC 20-35V switching power supply. The signal isolator samples 4-wire current signal and outputs 4-wire current signal after isolation. The advantage of this approach is high accuracy of isolation transmission. Power, input and output are completely isolated. Multi channel system power supply does not need isolation, thus ensuring a high anti-interference performance. The input signal can be converted to other types of signal.
Loop powered signal isolator
In the actual industrial monitoring system, DCS, PLC or other display instruments adopt cards internal power supply, the cards have higher requirement on the signal isolation transmission accuracy, so does the distribution voltage of a 2-wire transmitter. However, the external powered isolator can't meet these conditions. Therefore, the loop powered isolator is selected. Such a signal isolator provides working power supply to the 2-wire transmitter and samples the 2-wire current signal output by the transmitter. It converts the 2-wire current signal to 4-wire current signal after isolation and then output. In this way, it not only retains the superior performance of the external powered signal isolator, but also meets the requirements of the output loop powered interface.

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.
