On-machine starter will cut costs by up to 40%

Rockwell claims that a new IP67 motor starter system, designed to be mounted on or near a machine, will cut installation times and costs by up to 40%. The Allen-Bradley ArmorStart distributed starter system (shown below) is said to saves on enclosures, removes complex multi-core cabling, and to simplify design, commissioning, troubleshooting and maintenance.

The modular starter, which can be used for DOL (direct-on-line), reversing and variable speed applications, has a plug-and-play design which allows items such as reversing starters to be added in the field, without removing the base.

For DOL motors from 0.75-7.5kW, up to 460V AC, the system provides switch disconnection and adjustable overload protection. It can accommodate optional Powerflex variable speed drives up to 4kW. A LED display indicates faults such as phase losses, overloads and imbalances.

The starter has four inputs that can be used for sensors, as well as two outputs. A local control keypad is an option.

The system is designed to link into a DeviceNet network. It support`s Rockwell`s automatic device replacement technology so that when a damaged starter is replaced, the original settings are downloaded to it automatically from the PLC. If the network connection is lost, the starter will continue to operate.

The ArmorStart starter is the first in a series of distributed control products that Rockwell plans to launch under an initiative called On-Machine.
