Input Voltage Range: It refers to the range of input voltage within which the module can operate normally, such as AC 220V±10%, DC 24V±5%, etc.
Output Voltage/Current: The voltage amplitude or current magnitude of the output signal, such as an output of 0-10V, 4-20mA, etc.
Operating Frequency Range: The frequency range of the signals that the module can process, for example, 50Hz-1000Hz, or a higher frequency band.
Phase Measurement Range: Usually 0°-360°, indicating the range of phase angles that the module can accurately measure.
Phase Resolution: It reflects the module’s ability to distinguish phase changes, such as 0.1°, 0.01°, etc.
Accuracy Parameters
Phase Measurement Accuracy: It measures the accuracy of the module in measuring the phase, for example, ±0.2°, ±0.5°, etc.
Amplitude Accuracy: If the module processes the signal amplitude at the same time, it is the accuracy of its measurement or output amplitude, such as ±1%FS (Full Scale).
Communication and Interface Parameters
Communication Interface Type: Common types include RS485, RS232, USB, Ethernet, etc., which are used for data transmission and communication with other devices.
Interface Level: Such as TTL level, CMOS level, which determines the electrical compatibility when connecting to external devices.
Data Transmission Rate: The amount of data transmitted per unit of time, such as 9600bps, 115200bps, etc.
Environmental Parameters
Operating Temperature Range: The temperature range within which the module can operate normally, generally -20°C-60°C or wider.
Storage Temperature Range: The temperature range in which the module can be stored when not in operation, usually wider than the operating temperature range.
Humidity Range: The relative humidity range of the module’s working environment, such as 5%-95%RH without condensation.
