Analog Correspondence Table

Type	Acquisition Data (12-bit AD)	Example
4-20mA	0~4095	4mA corresponds to 819 (0mA corresponds to 0), and 20mA corresponds to 4095. e.g., if the read data value is 3000, the measured output current signal is: (3000/4095)*20mA=14.65mA.
0~5V	0~4095	Example: If the read data value is 300, the measured output current signal is: (300/4095)*5V=0.37V.
0~10V	0~4095	Example: If the read data value is 1000, the measured output current signal is: (1000/4095)*10V=2.44V.

Applications

Tips: What signal input types does the 4-channel converter support?

The 4-channel converter supports a variety of input signal types, including 4-20mA current signals, 0-5V and 0-10V voltage signals. Each channel can be individually configured for flexible adaptation to different sensors or devices. Whether for industrial automation, environmental monitoring or other applications, the device can meet the diverse signal conversion needs.

Connection and configuration is very simple, the device comes with clear terminal identification and instructions. The inputs are used to receive analog signals (4-20mA, 0-5V or 0-10V), while the outputs transmit data via RS485. Users can set up communication through the accompanying software or the standard MODBUS protocol, which supports parameter configurations such as baud rate, device address, etc., to quickly complete commissioning and deployment.

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.
