Series Description

Introduction

The PT-7528 Series is designed for power substation automation applications that operate in extremely harsh environments. The PT-7528 Series supports Moxa’s Noise Guard technology, is compliant with IEC 61850-3, and its EMC immunity exceeds IEEE 1613 Class 2 standards to ensure zero packet loss while transmitting at wire speed. The PT-7528 Series also features critical packet prioritization (GOOSE and SMVs), a built-in MMS server, and a configuration wizard designed specifically for substation automation.

With Gigabit Ethernet, redundant ring, and 110/220 VDC/VAC isolated redundant power supplies, the PT-7528 Series further increases the reliability of your communications and saves cabling/wiring costs. The wide range of PT-7528 models available support multiple types of port configuration, with up to 28 copper or 24 fiber ports, and up to 4 Gigabit ports. Taken together, these features allow greater flexibility, making the PT-7528 Series suitable for a variety of industrial applications.

Additional Features and Benefits

  • Switch data modeling based on the IEC 61850-90-4 standard

  • Fiber Check™ provides monitoring and diagnosis functions on MST/MSC/SSC/SFP fiber ports

  • VLAN Unaware: Supports priority-tagged frames to be received by specific IEDs

  • EtherNet/IP and Modbus TCP industrial Ethernet protocols supported

  • Configurable by web browser, Telnet/Serial console, CLI, Windows utility, and ABC-02 automatic backup configurator

  • Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 switches),

    RSTP/STP, and MSTP for network redundancy

  • DHCP Option 82 for IP address assignment with different policies

  • IGMP snooping and GMRP for filtering multicast traffic from industrial Ethernet protocols

  • IEEE 802.3ad, LACP for optimum bandwidth utilization

  • Automatic warning by exception through email and relay output

  • RMON for proactive and efficient network monitoring

  • Automatic recovery of connected device’s IP addresses

  • Line-swap fast recovery

  • Noise Guard™ provides a high level of EMC immunity for critical applications, exceeding IEEE 1613 Class 2

Cybersecurity Features

  • User passwords with multiple levels of security protect against unauthorized configuration

  • SSH/HTTPS is used to encrypt passwords and data

  • Lock switch ports with 802.1X port-based network access control so that only authorized clients can access the port

  • RADIUS/TACACS+ allows you to manage passwords from a central location

  • 802.1Q VLAN allows you to logically partition traffic transmitted between selected switch ports

  • Secure switch ports so that only specific devices and/or MAC addresses can access the ports

  • Disable one or more ports to block network traffic

  • SNMPv3 provides encrypted authentication and access security
