MOXA DA-662A-8-LX Rackmount Industrial Computer


The DA-660A Series Arm-based, ready-to-run embedded computers are designed for industrial data-acquisition applications. The computers have 8 to 16 RS-232/422/485 serial ports, 4 Ethernet ports, and 2 USB 2.0 ports, all based on the MoxaMacro communication processor. In addition, the DA-662A-I-8/16-LX’s serial ports come with high-level interference protection. The housing is a standard 1U, 19-inch wide rack-mountable rugged enclosure. The robust, rack-mountable mechanism design provides the hardened protection needed for industrial environment applications, and makes it easy for users to install the DA-660A computers on a standard 19-inch rackmount.

The DA-660A computers are ideal for applications that require a distributed embedded technology, such as SCADA systems, plant-floor automation, and power electricity monitoring applications.
