Method of using signal isolators

The signal isolator refers to a signal conversion device, which is used to isolate and convert different levels and different types of signals transmitted within industrial automation components. It has two modes of digital output and analog output, and has been widely used to accurately solve various market conditions. In actual use, the following points need to be noted:

1. Connect signal cables correctly

For the use of signal isolators, the first problem is to connect the signal line correctly. Because the correct connection is essential to ensure the correct transmission of the signal, it is important to follow the corresponding mark or connection instructions when connecting.

Second, choose the right power supply

Signal isolators need external power supply to work properly, usually we use AC or DC power supply for power supply. It should be noted that the power supply voltage and power specifications need to meet the rated standards required by the equipment. At the same time, special attention should be paid to the longitudinal and horizontal distance of the power cable, as well as the spacing with other pipelines, to reduce electromagnetic interference.

3. Set input parameters

The next step for the signal isolators produced by Taihua Instruments is to gain an in-depth understanding of the current network environment and then set the appropriate input parameters based on this. For each individual input channel, there are many options that can be customized, including ground connection, servo self-test, correction factor, and activation. It is important to note that before setting any parameters, make sure the device is powered off to avoid damage.

4. Set output parameters

Once the appropriate input parameters have been set, the next step is to proceed with setting the appropriate output parameters. This ensures that all the data you need is transmitted correctly and that there is no adverse impact on the overall system design

5. Check and calibrate the signal isolator

After these operations are performed, the entire equipment needs to be inspected and calibrated. If there is an anomaly or error in the process of operation, it is necessary to first consider the diagnosis of signal line cross induction disease. Precise tools are required to measure current, impedance, confusion, refractive index and other relevant parameters, and should be calibrated according to the operating manual.

In short, the signal isolator as an important signal conversion equipment, can be widely used in the field of industrial automation. When in use, we need to carefully read the equipment manual, understand the function and characteristics of the signal isolator, and pay attention to the correct connection and setting of the corresponding parameters to achieve reliable signal transmission and accurate processing.
