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.
