3-Phase Motor Control

TURCK (Minneapolis, MN) released the BL20 xStart motor starter modules that allow 3-phase motor control to be connected to the same rack as standard I/O. The units may be mounted next to other BL20 modules, allowing motors to be controlled via DeviceNet, Profibus-DP, or CANopen fieldbus protocols.

The starters contain a base and power module and are available in direct online and reversing models. The base contains the I/O and communication electronics, and can be configured for power modules of various ratings, while the power module contains a circuit breaker and contactors. Power modules are hot-swappable, and enable the connection of motors rating up to seven horsepower at a rated operation voltage of 480 VAC.
