KXT2731 Three-Phase AC Current Transmitter
KXT2731 is a 3-phase AC current transmitter designed around “Monitor Three-Phase Current in One Device.” It collects A/B/C three-phase current signals simultaneously within one compact transmitter, replacing three separate single-phase transmitters. Multiple current ranges up to AC 0–450A and selectable aperture sizes help adapt the device to different three-phase power monitoring requirements.
KXT2731 provides three independent output channels corresponding to the A/B/C phase measurements. Each phase can be transmitted separately to downstream monitoring and control equipment, with standard signal options including 4–20mA and 0–10V. This independent channel structure makes three-phase current information easier to integrate into PLC, DCS and power monitoring systems.
KXT2731 uses three-terminal galvanic isolation between the input, output and auxiliary power circuits. With 2000V AC / 1min isolation withstand capability, the isolated architecture helps suppress common-mode interference and provides electrical separation between field current measurement and downstream control equipment.
