The explosion-proof signal isolator uses three-terminal isolation of the input, output and power supply, and has the advantages of low power consumption and good temperature characteristics.

Features

The explosion-proof analog signal isolator adopts a 12.7mm slim design to save installation space.
Its power consumption is as low as 1.0W, with low heat generation and rapid heat dissipation, which extends the service life of the equipment.
The explosion-proof signal isolator has a high accuracy of 0.1%FS, ensuring accurate signal conversion and more accurate data.
Its response speed is as low as 2ms, the system responds quickly and enhances reliability.
The signal isolator adopts a pluggable design and snap-on terminal blocks, which is simple and quick to install and easy to maintain and replace.
It supports active and passive signals, is compatible with two-, three- and four-wire signal output, and adapts to a variety of industrial application needs.

Applications

Tips: Main applications of explosion-proof signal isolators

Oil and gas industry: used in oil and gas extraction, refineries and oil storage areas to ensure safe isolation of signals in hazardous environments and prevent explosions caused by electrical faults.
Chemical industry: provides signal isolation in chemical production and corrosive environments to protect control systems from high-risk gases and chemicals.
Mining industry: used in coal mines and metallurgical plants to isolate signals in gas monitoring and automation control systems to avoid explosions caused by electrical faults.
Power and energy industry: widely used in power plants, wind and solar power generation systems to ensure the stability and safety of signal transmission.
Automation control system: in automation systems such as PLC and DCS, isolate field equipment signals to protect control systems from electrical interference.

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.
