Introduction
DA-720-Ethernet peripheral expansion modules include a 4-port Giga LAN module, an 8-port Giga LAN module, and a PRP/HSR module for setting up industrial communication applications with Ethernet-based devices. All modules are designed to offer the greatest flexibility for setting up applications and performing industrial tasks.

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 DA-PRP-HSR module provides high performance for redundant network systems. Moxa’s DA-720 Series industrial computer with the DA-PRP-HSR module installed is the ideal solution for power substation automation and process automation systems.
