Function

The picture shows the way an application module with MCU system together constitute the signal conversion, isolation transfer functions.

Working principle

As shown, the signal conditioning modules VLoop take power from the output circuit for signal input device provides one isolated power Vo +;MCU

for the first stage of the system power supply.The strain sensor output signal after signal conditioning modules into the MCU system, by the MCU

system the collected signal processing, computing, and then the D / A converter, converted to a voltage signal.Module receives the voltage signal,

the internal precision isolation transferred to the output, and converted to 4 ~ 20mA standard signal output to VLoop loop.

The system of the sensor signal to the4~ 20mA standard current signal isolation transmission, the output remotely, using the sampling resistor

RL, the current signal can be converted toa voltage signal, the various instruments of the type of input signal to the output of the module match.
