2-Channel RS-422 Sync Serial over IP Gateway

Rollover or Touch for Expanded View. Scroll to Zoom.


Featuring support for teleprotection relays, the TC3847-4 RS-422 Gateway Card transports 2 channels of RS-422 Sync serial data over existing Layer 2/Layer 3 networks.

The JumboSwitch® series is a TDM over IP/Ethernet based solution designed to emulate time-division multiplexing over packet switched networks (PSN). TDM over IP/Ethernet is a TDM pseudowire (PW) technology making it possible to provision E1, T1, E3, T3, STS-1 and serial data services across PSN's such as IP, MPLS or layer 2 Ethernet Networks.

  • 2-Channel RS-422 Sync Serial
  • Extremely Low Latency
  • VLAN QoS Support
  • Increased Security Features
  • Built-In Temperature & Power Sensors
  • Extreme Temp (-40°C to +80ºC) Optional
  • Meets or Exceeds IEC 61850-3, IEEE 1613 & NEMA TS-2 Standards
  • Member of JumboSwitch® Product Family


Typical applications include extending serial data across IP networks.

For example, the TC3847-4 is often used to extend RS-422 signals from one protection relay to another across Layer 2/Layer 3 Networks.
