How does a pulse card send signals?

Sending signals when pulsing is used for DCS inspection is usually accomplished through dedicated software tools or by operating the DCS system. The specific steps are as follows: 1. Open the DCS system or relevant software tools. 2. Select the output channel corresponding to the pulse card to be inspected. 3. Set the frequency and pulse width of the pulse signal to be sent. 4. Send a pulse signal. Receiving and error detection are usually accomplished by comparing the actually received pulse signal with the transmitted pulse signal. The steps are as follows: 1. Use an oscilloscope or the monitoring function in the DCS system to receive the signals sent by the pulse card. 2. Record the frequency and pulse width of the received signal. 3. Compare the recorded data with the data set when it was sent. 4. Analyze the differences between the two to determine whether they are within the allowable error range. If the error exceeds the allowable range, it may be necessary to adjust the settings of the pulse card or perform maintenance. In practice, please follow the instruction manual provided by the equipment manufacturer to ensure that the inspection is carried out correctly and safely. .
