For Substations Looking to Save, Pick Your Interface, No Worries: DA-685 Computers



Taipei, Taiwan, August 1, 2012—The DA-685 is a 19” 2U rackmount computer tailored for substation applications, featuring abundant communication ports and precision timing capabilities. For substations looking to save, simply pick your interface and worry no more: the DA-685 rackmount computer fits your need!


Moxa’s successful rackmount substation computers, the DA-681 and DA-683, are already steadfastly serving in numerous power substations the world over. The IEC 61850-3 certified DA-681 was designed to provide a large variety of communication ports, while the DA-683 combined the Precision Time Protocol, version 2 (IEEE 1588v2), with a high performance dual core Intel Atom D510 processor. These exceptional solutions have inspired many requests for a rackmounted substation computer that combines the exceptional IO capacity and variety of the DA-681 with the computing power of the DA-683. Moxa is now pleased to unveil our response: the DA-685. Like the DA-683, DA-685 series computers feature the Intel Atom D510 processor, giving you all the computing power you need in a reliable, fanless design that features the same variety and number of communications interfaces as the DA-681, but bundled with PTPv2 and EMC Level 4 certification, as well. Designed as an all-purpose substation solution, these DA-685 computers are capable of serving virtually any role in a smart grid environment, regardless of what environmental or technological demands are required.
