Overview
The ABB ACS355-03U-12A5-4+B063+C169+F278+N826 is a high-performance 7.5 HP, 3-phase industrial machinery drive from ABB’s Low Voltage Drives portfolio. Designed for precision and durability, this drive delivers a rated output current of 12.5 A and operates on a 480 VAC supply, with a wide input voltage range of 380-480V to accommodate global power standards. Its UL TYPE 4X (IP66) certification ensures exceptional resistance to dust, water, and corrosive elements, making it ideal for demanding industrial settings such as food processing, chemical plants, or outdoor installations.
Engineered for versatility, the ACS355 features a wall-mountable design with a compact footprint of 17.17 inches (height) x 9.69 inches (width) x 10.91 inches (depth) and a lightweight build of 28.66 lbs, simplifying installation and maintenance. The drive includes an advanced operator panel for real-time monitoring and adjustments, while a built-in pressure compensation valve maintains internal pressure balance in fluctuating atmospheric conditions. A non-fusible service switch enhances safety by allowing quick disconnects without the need for additional fuse components.
Optimized for high-speed applications, the ACS355 supports both 3-phase input and output configurations, ensuring compatibility with a broad range of motors and machinery. Housed in frame size R3, this drive combines ABB’s engineering excellence with robust construction, delivering reliable performance in critical industrial processes.

FENA-21
The FENA 21 DualPort module supports Three protocols Modbus-TCP, EtherNet/IP, and the PROFInet IO RT network. The Modbus-TCP protocol is simply the Modbus protocol used on top of Ethernet-TCP/IP. Modbus-TCP is an open Industrial Ethernet network which has been specified by the Modbus-IDA User Organization. EtherNet/IP is based on the Common Industrial Protocol (CIP), which is also the framework for both the ControlNet and DeviceNet network protocols. PROFInet IO RT is an open network based on the PI Organization standard.
