Distributed motor controller is sealed to IP69K
Rockwell Automation is expanding its ArmorStart product line to include IP69K/NEMA 4X rated variants of its Bulletin 280/281/283 and 284 distributed motor controllers. These new additions will enable users in food and beverage applications to benefit from lower installation costs, reduced engineering times and ease of maintenance. In addition, the ArmorStart product line voltage ratings have been expanded to include 575V versions for all the products in the range, including the Bulletin 284 with built-in PowerFlex 40 drive.
The ArmorStart is an integrated, pre-engineered enclosed motor controller designed for quick and easy installation. Its pre-tested, quick-connect wiring assembly minimises cabling, cuts labour costs and helps reduce wiring problems. In addition, the compact, space-saving design enables the units to be mounted near the motor rather than in a separate control cabinet. This removes the need for complex multi-core field wiring, minimises space requirements and can reduce installation times by up to 30 per cent. An innovative gland plate design enables either a traditional cable entrance or use of the Allen-Bradley ArmorConnect system for even easier installation.
CE marked and cULus-listed, the ArmorStart has already proved extremely popular in applications such as materials handling, mining and automotive assembly. The new IP69K/NEMA 4X versions extend the benefits of ArmorStart into the harsh environments typically encountered in food and beverage applications. Together with a washdown rating of 1000psi, the new NEMA 4X rated ArmorStart products are resistant to caustic cleansing agents such as sodium hydroxide. White enclosures and the use of stainless steel on all exposed metalwork make them extremely suitable for hygiene-controlled environments.
Advantages of peer-to-peer networking
The built-in peer-to-peer connectivity of the ArmorStart Distributed Motor Controller makes it suitable for conveyors with large motors. Along with on-board DeviceNet communications and DeviceLogix technology, ArmorStart's Zone Interlocking Parameters (ZIP) enable it to receive data directly from up to four other DeviceNet nodes without going through a network controller. Peer-to-peer networking also greatly improves efficiency in conveyor applications such as merge, diverter and accumulation.
ArmorStart's built-in diagnostic functions simplify maintenance and troubleshooting. The built-in LED display indicates the device's status and fault conditions such as overload, open control or DeviceNet power, I/O fault, communication problem, etc – enabling technical personnel to identify problems quickly and efficiently.
Food and beverage manufacturers looking for high-performance control devices will appreciate the flexibility, faster installation and lower engineering costs of an ArmorStart Distributed Motor Control.
