Beckhoff KL3464 original analog input

The KL3464 is a three-phase power measurement terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system, designed for direct measurement of electrical power in three-phase AC systems. It measures voltage and current on all three phases and calculates RMS values, active/reactive/apparent power, power factor, frequency, and energy, delivering the results to the controller. It belongs to the KL34xx power measurement family; the exact feature differences versus the KL3403, KL3404, KL3444, KL3454, and other variants should be confirmed in the current Beckhoff datasheet.
