Multi-functional electronic motor starter eases installation
This makes the connection of the motor starter to the automation environment easier, faster, less prone to errors and therefore more cost-effective, claims the company. The EMS offers users in industrial and machine building applications all the important functions of a reversing contactor circuit in a single device – and this with a mounting width of only 30 mm.
Wiring is kept to a minimum. Both the control cables that normally connect the motor starter via the I/O level to the PLC, and the supply cables to the devices are replaced by Eaton’s green cable. Even the I/O level itself is unnecessary as the motor starters can communicate with the Eaton PLCs directly via SmartWire-DT.
The electronic motor starter itself already comes with a large number of functions (emergency stop contactor, motor protection, clockwise and anticlockwise contactor) as well as the internal load and interlock circuits. It is based on a MCU-controlled combination of wear-free semiconductor technology and a robust relay contact, thus enabling low-wear switching. With 30 million switch operations the devices offer a considerably longer contact life than conventional switching devices.
