4-Channel Turbo Serial-Over-IP

Rollover or Touch for Expanded View. Scroll to Zoom.


The TC3847-3 Turbo Serial Card features support for teleprotection relays, and transports four channels of RS-232 or RS-422/ RS-485 serial data over existing Layer 2/Layer 3 networks at extremely low latency.

Typical applications for the TC3847-3 include extending serial data across Ethernet/IP, CE, or MPLS networks.

  • 1, 2 or 4 Channels of RS-232/RS-422/RS-485 Serial
  • Data Rates up to 115200 bps
  • Extremely Low Latency
  • Protocol Transparent: Mirrored Bits*, DNP-3, Modbus, etc.
  • RS-232 Supports Handshaking or Synchronous Mode
  • Built-In Temperature & Power Sensors
  • Extreme Temp (-40°C to +80ºC) Optional
  • Meets or Exceeds IEC 61850-3, IEC 60834, IEEE 1613 & NEMA TS-2 Standards
  • Member of JumboSwitch® Product Family

Typical applications include extending serial data across Ethernet/IP, CE, or MPLS networks.

Specially designed to meet stringent real time requirements for protective relay communications in the power utility industry, this Turbo Serial interface card can perform at less than 3msec. latency, end-to-end, through an Ethernet network. This extremely low latency is irrespective of the protocol used, mirror bit or otherwise, and is unaffected by the number of nodes in between.

In short, it's the fastest serial-over-IP solution for teleprotection currently available in the industrial marketplace today.

For example, the TC3847-3 is often used to extend RS-232/ RS-422/RS-485 signals from one protection relay to another over an Ethernet/IP network.
