Serial Link Replacement—Replace leased or dial-up communication lines, or add Ethernet communications to sites where other communication types are prohibitive. Use serial tunneling for a virtual serial link through the network.

Ethernet Access to Serial Devices—Access devices with serial ports via Internet protocols over a standard Ethernet network. Streamline terminal access and save engineering time by using Telnet for ASCII terminal dialogs. Simplify and control data access with a webpage on your private network.

Automatic Email Event Reports—Send email alerts based on automatic messages from an SEL relay host device to improve customer service. Configure the transceiver to automatically communicate with a Simple Mail Transfer Protocol (SMTP) server available on an operations network.

DNP3 Tunneling—Inexpensively tunnel serial-based DNP3 traffic over an existing Ethernet network. Simply connect a transceiver to the DNP3 serial master and DNP3 serial clients, and configure the DNP3 settings.


Connects EIA-232 Port to 10BASE-T Ethernet Connection

Powered by 5Vdc in EIA-232 Connector

  • Receive power via a jumper in most SEL device serial ports.
  • Provide power through a SEL-C642 Cable for use with PC or other devices.

Hardened for Substation Environment

  • Trust in the same design and type testing as applied to critical protective relays.
  • Employ in environments with temperature ranges of –40° to +85°C (–40° to +185°F).

Hosts Telnet ASCII Data With Embedded Web Server

  • Access relay data with web browser software on your private network.
  • Use the included default webpage that is hosted in SEL-2890.
  • Upload, customize, and download the webpage using FTP.

Allows Setting From PC Using Terminal Emulation Software and SEL-C642 Configuration Cable

  • Configure network addressing parameters.
  • Enable/disable features.

Sends Email Automatically

  • Improve customer service by sending messages for quick notification and logging.
  • Specify address via setting.
