Connection Schemes for PLCs and Various Sensors (Including Application Diagrams)
In industrial sites, various analog sensors such as pressure, displacement, temperature, flow, and speed differ in their design and technical methods. The power distribution methods for sensor operation are mainly divided into two-wire and four-wire systems, and the output analog signals also vary, with common signals being 0-20mA, 4-20mA current signals, and 0-75mV, 0-5V, 1-5V … Read more
