This is the 256th content shared by the platform.In process control systems, sensor transmitters collect data such as pressure, temperature, flow, and level, and send this information to a Programmable Logic Controller (PLC) or Distributed Control System. These transmitters rely on 4-20mA signals to send data to the controller. Despite the emergence of standards like … Read more
The circuit illustrated is an 8-bit T-type resistor network D/A converter (DAC), whose core function is to convert digital signals into analog voltages through a resistor network. Below is a detailed analysis of the circuit logic: 1. Circuit Structure and Component Functions 1.1 Resistor Network: Utilizes an R-2R type resistor network, consisting of only two … Read more
Click the blue text Follow us 1. First of all, UART and TTL are completely different concepts. UART stands for Universal Asynchronous Receiver/Transmitter, which is a serial asynchronous communication protocol. The TTL level signal specifies that +5V is equivalent to logic “1” and 0V is equivalent to logic “0” (when using binary to represent data). … Read more
With the rapid development of manufacturing processes, the complexity of miniaturized devices is increasing day by day.
