The Moxa EDS-405A-PTP is an industrial network switch of the EDS-405A series, designed for use in demanding industrial environments. It features five 10/100BaseT(X) Ethernet ports with RJ45 connectors and supports hardware-based IEEE 1588 PTPv2 protocol implementation, making it suitable for applications requiring high time accuracy. The operating temperature ranges from -10 °C to 60 °C, enabling use in various industrial scenarios.

Applications

The switch is designed for use in industrial networks, particularly in systems requiring precise device synchronization, such as in automation technology, manufacturing industry, or energy supply. Support for EtherNet/IP and Modbus TCP ensures compatibility with common industrial communication protocols. The integrated Turbo Ring and Turbo Chain redundancy functions ensure rapid network connection recovery in case of failure, which is important for critical applications.

Functions and Equipment in Detail

The EDS-405A-PTP offers a variety of network functions, including VLAN support (802.1Q), port-based VLANs, GMRP and GVRP for dynamic group management. IGMP v1/v2 support enables efficient multicast traffic management. The MAC address table includes 8 K entries, and up to 64 VLANs can be configured. The packet buffer size is 1 Mbit, ensuring stable data transmission. Priority queues (4 queues) support differentiated data traffic handling.

Technology Explained Simply

The hardware-based IEEE 1588 PTPv2 support enables precise time synchronization between network devices, reducing time deviation to microseconds. This is especially important for applications where synchronization of sensors, actuators, or control devices is critical. Rapid Spanning Tree Protocol (RSTP) support prevents network loops and enables fast convergence during topology changes. SNMPv1/v2c/v3 support, along with RMON and Syslog, provides comprehensive monitoring and management capabilities.

Compatibility and Accessories

The switch is compatible with EtherNet/IP and Modbus TCP, facilitating integration into existing industrial networks. The Turbo Ring and Turbo Chain redundancy protocols can be combined with other Moxa switches to create redundant network topologies. The DIP switch configuration allows setting roles such as Master, Coupler, or Reserve, providing flexible network configuration.

Mounting and Installation

The switch can be mounted on a DIN rail, simplifying installation in enclosures. Wall mounting is also possible, requiring an optional mounting kit. The input power supply is via a 6-pole, detachable terminal block and supports redundant dual inputs. The operating voltage ranges from 9.6 V to 60 V DC, including input voltages of 12 V, 24 V, and 48 V DC. Overload and reverse polarity protection functions protect the device from damage.

Operational Advantages

The high MTBF of 1,316,464 hours (according to Telcordia and GB standards) demonstrates the high reliability of the device. The IP30 protection rating protects against contact and offers some protection against solid foreign objects. EMC and safety certifications (UL 508, EN 55032/35, CISPR 32, FCC Part 15B Class A) ensure compliance with international standards. The 5-year warranty underscores the product’s quality.

Additional Interfaces

An RS-232 console port (10-pin RJ45 connector, 115200, n, 8, 1) enables local configuration and maintenance. A relay output with a current capacity of 1 A at 24 V DC serves as an alarm contact to activate external devices in case of network failures or other events.

Standards and Certifications

The switch complies with standards IEEE 802.3, 802.3u, 802.3x, 802.1D-2004, 802.1p, 802.1Q, 802.1w. EMC tests include ESD, RS, EFT, Surge, CS, and PFMF according to IEC 61000-4-2 to -4-8. Mechanical stress tests are certified according to IEC 60068-2-6 (vibration), -2-27 (shock), and -2-31 (free fall).

Environmental Conditions

The operating temperature ranges from -10 °C to 60 °C, and the storage temperature ranges from -40 °C to 85 °C. Relative humidity is 5 to 95 % (non-condensing). Physical dimensions are 53.6 mm (H) × 135 mm (W) × 105 mm (D), and the weight is 820 g.

Management and Security Functions

Network management is performed via SNMP, Telnet, TFTP, DHCP, BOOTP, RMON, Syslog, SMTP, LLDP, and MIBs (Bridge MIB, Ethernet-like MIB, MIB-II, P-BRIDGE MIB, RMON MIB Groups 1, 2, 3, 9, RSTP MIB). Security functions include Broadcast Storm Protection, HTTPS/SSL, SSH, SNMPv3, Port Lock, Trust Access Control, and NTP authentication.

Time Management

Time management is handled via NTP server/client, SNTP, and hardware-based IEEE 1588v2 PTP, enabling precise synchronization.
