Introduction
The DA-720 Series computers are x86 platforms with 14 Gigabit Ethernet ports, 2 isolated RS-232/422/485 serial ports, USB, VGA, and 3 PCIe ports for expansion modules. The DA-720 comes in a standard 19-inch 2U rack-mountable case with a robust design ideal for specialized industrial automation applications, including power substations, transportation and shipping, and oil and gas production and supply.

With IEC-61850-3 and IEEE 1613 compliance, the DA-720 is sure to deliver stable and reliable system operation for power applications. The DA-720 also complies with the IEC 60255 standards, which cover the protection of electrical relays in a smart substation. IEC 60255 is one of the most widely used standards for testing relays and protection equipment, and compliance with the standard ensures that the DA-720 will work reliably and seamlessly with IEDs as part of a robust substation automation system.

EN 50121-4 compliance confirms that the DA-720 can deliver stable and reliable system operations in rail wayside applications, such as station SCADA systems, wayside disaster prevention, traction power, and signaling and safety systems to provide an integrated view of your smart rail setup.

The DA-720 comes with two different CPU options and basic models that allow system designers to install the mSATA, RAM, and operating system according to their specific requirements. Such a wide choice of options is particularly welcome when it comes to designing customized industrial solutions.

The DA-720 comes with 3 PCIe ports for expansion modules, including an 8-port RS-232/422/485 module, 4-port and 8-port 10/100/1000 Mbps LAN modules, a 2-port 100/1000 Mbps PCIe PRP/HSR LAN module, a dual 2.5” SATA III SSD/HDD socket module, and a 2-port IRIG-B time-synchronization module with a 4 DI/DO module. The DA-720 computers can support up to 22 Gigabit LAN ports plus 16 serial ports, or 14 Gigabit LAN ports and 24 serial ports, making the DA-720 an ideal solution for a wide range of industrial automation applications.

The PRP-HSR expansion module is compliant with IEC 62439-3 Clause 4 (PRP) and IEC 62439-3 Clause 5 (HSR) to ensure the highest system availability and data integrity for mission-critical applications that require redundancy and zero-time recovery. With dual Gigabit Ethernet port design, the DE-PRP-HSR-EF provides high performance for redundant network systems. Moxa’s DA-720 Series industrial computer with the DE-PRP-HSR-EF is the ideal solution for power substation automation and process automation systems.

Smart Recovery Function
The DA-720’s Smart Recovery function minimizes downtime by making it easy to recover from operating system crashes. Engineers who are experts in a particular vertical market may not have enough computer domain knowledge to know how to fix operating system problems. Moxa Smart Recovery™ is an automated BIOS-level software recovery system that allows engineers to automatically trigger OS recovery to minimize downtime.

Proactive Monitoring Function
Moxa Proactive Monitoring is a small-footprint, resource-friendly, easy-to-use utility that allows users to track a number of system parameters. Users can view the current parameter values for these key parts by simply clicking on the icons corresponding to the parameters in the user interface. User-defined key part indicators (KPIs) are used to monitor the computer’s key parts. Visible and/or audio alerts are triggered automatically via relay and SNMP traps when these KPIs exceed their preset threshold values, making it extremely convenient for operators to avoid system downtime by setting up predictive maintenance tasks well in advance.
