Overview
The ABB ACS355-03U-23A1-4 AC drive is engineered for precise speed control in pump and fan applications, offering robust performance with a 1.5x overload capacity. This open-type drive is rated for 15HP and 23.1A, with an input voltage range of 380-480V. Its compact module dimensions (9.29" H x 6.65" W x 6.65" D) facilitate easy integration into standard enclosures, making it ideal for OEMs. The ACS355 series is specifically designed for variable torque applications, contributing to significant energy savings of up to 30% compared to traditional methods like throttled valves or dampers. This drive supports efficient operation in HVAC, water treatment, and industrial ventilation systems where variable flow control is critical. For seamless integration, the ACS355 features blank faceplates and DIN rail mounting compatibility, along with support for Modbus RTU and other fieldbus protocols. ABB's drive tools are available for straightforward commissioning and diagnostics, ensuring operational efficiency and reliability. Manufactured in Denmark (DK) with UNSPSC code 39122001.

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.
