The JXK-D21U-Z true RMS transmitter is designed around “Versatile AC/DC Voltage & Current Measurement,” supporting different electrical input configurations within one product platform. It can be configured for AC voltage, DC voltage, AC current or DC current measurement according to application requirements. This flexibility allows the transmitter platform to serve different industrial electrical monitoring needs without requiring a completely different product architecture for each signal type. Engineers can select the appropriate input configuration based on the measured electrical signal and project specifications.
The JXK-D21U-Z true RMS transmitter is designed around “Dual True RMS Measurement Modes,” providing selectable AC+DC total RMS and AC-only measurement for different electrical signal characteristics. The default AC+DC mode calculates the total effective value of a signal, including both alternating and direct components. When only the alternating component needs to be measured, AC-only mode removes the DC average before calculating its RMS value. Engineers can select the appropriate measurement mode through the designated mode-selection pins according to application requirements.
The JXK-D21U-Z true RMS transmitter is designed around “Flexible Output Configuration,” offering selectable analog and digital interfaces for different industrial monitoring and automation systems. The standard configuration provides a 4–20mA output, while 0–10V, 0–5V, RS485 and CAN options are available through corresponding hardware configurations. These output choices allow the transmitter to interface with conventional analog acquisition equipment or digital communication systems according to project requirements. Engineers can select the appropriate output type during product specification to match the intended control system.
