At present, most of the current and voltmeters on the market use simple rectification and averaging circuits to complete the measurement of AC signals. There are large theoretical errors. Therefore, these meters can only be used for standard undistorted sine waves when measuring the effective value, if it is a non-sine waveform Or the measured result of the distorted sine wave does not match the actual value of the signal. The true effective value transmitter adopts the averaging technique of signal integration after squared. It is used for accurate measurement of standard sine wave or aperiodic, non-sine wave and superimposed DC level of various noises, without considering waveform parameters and distortion. These performances are The average value measuring instrument cannot be realized.

The switch input isolator receives the signal from the switch or proximity switch, and transmits it to the control system or other intelligent instruments through a relay with changeover contact output through isolation.
