Power measurement terminal for
three-phase control
The KL3403 power measurement terminal allows industrial machinery users to incorporate measurement and control of their three-phase motors into the Beckhoff bus terminal I/O system.
The cost of power is becoming more and more of an issue within industrial applications, and engineers are being asked to monitor and control this increasingly expensive element But the tools to do this are still expensive and/or complex to set up

Beckhoff Automation has announced the Beckhoff Bus Terminal, a modular I/O system compatible with all current and future fieldbus technologies, including Ethernet
With the introduction of the KL3403 power measurement terminal, industrial machinery users can now easily incorporate measurement and control of their three-phase motors into the Beckhoff bus terminal I/O system.
Preprocessing within the KL3403 provides RMS values in the process image, without requiring high computing capacity on the controller.
From the RMS value for voltages (U) and currents (I), the KL3403 calculates the effective power (P) and the energy consumption (W) for each phase.
By relating this RMS value to the effective power, the apparent power (S) and the power factor (cos j) can be derived.
The KL3403 thus enables a comprehensive network analysis to be carried out over a communications network since the module works with any of Beckhoff's bus couplers (DeviceNet, Profibus, Ethernet, CANopen, Interbus etc).
Based on the values for voltage, current, effective power, apparent power and loading condition, the plant operator can optimise the supply of a drive or a machine and protect the plant from damage and downtime.
At a list price of US $175, the KL3403 provides an economical way of managing three-phase power devices.
