EDS-405A-PTP 5-port IEEE 1588v2 PTP managed Ethernet switches

Time synchronization is increasingly important for distributed systems in industrial automation. To meet this need, Moxa has implemented the latest PTP (Precision Time Protocol) technology in their new line of EDS-405A-PTP switches. The switches support the IEEE 1588v2 real-time clock, which is required to synchronize the clocks of all connected devices to sub-microsecond accuracy.

The EDS-405A-PTP is a 5-port IEEE 1588v2 PTP switch designed for real-time factory automation, process control, and motor control applications. When the EDS-405A-PTP is configured as a boundary clock, the switch can act as a slave related to the grandmaster clock, and simultaneously act as a master clock related to its local slaves. The managed switch uses nanosecond-accurate time stamps to modify its timing packets and synchronize clocks distributed over the network. This PTP switch can also act as a transparent switch that measures the residence time of PTP packets and modify the time stamps to improve synchronization accuracy. The EDS-405A-PTP not only eliminates the master clock’s processing load, real-time synchronization also minimizes delays and disruptions to support precision control of robotic systems, now commonly used as part of advanced manufacturing applications.

The EDS-405A-PTP industrial Ethernet switch also supports Modbus TCP, PROFINET, l20140825102549and EtherNet/IP protocols for easy SCADA/PLC management and monitoring, and features a fast boot up time of less than 10 seconds, and fast network recovery within 20 ms with a full load of 250 switches. Other management functions such as IGMP snooping, IEEE 802.1Q VLAN, QoS, RMON, and relay warning, make network planning more flexible and easy. The compact size, fanless design, and wide operating temperature range make the EDS-405A-PTP a perfect choice for device level networks in harsh industrial environments.
