DIN Rail Managed Ethernet Switch & Serial Server

Rollover or Touch for Expanded View. Scroll to Zoom.


Compact and efficient the TC3847-1DR is fully managed Industrial Ethernet switch solution with full JumboSwitch® network compatibility and integrated Serial Server supporting transport of four channels of RS-232 or RS-422/RS-485 data.

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.

  • Compact Chassis with Full Management
  • Base Unit with 2x GigE SFP** Ports +6x 10/100Base-T
  • Expansion Card with 4 Channels of RS-232 or RS-422/RS-485
  • Dual-Master Mode Supported for Redundant Poll-Response Application over Network (Optional)
  • Ethernet Rate Limiting, VLAN, QoS
  • Built-In Temperature & Power Sensors
  • Industrial Hardened & IEC 61850-3, IEEE 1613 & NEMA TS-2 Compliant
  • Member of the JumboSwitch® Product Family


An all-in-one connectivity solution for industrial automation and commercial network applications, the TC3847-1DR benefits users by offering Managed Ethernet Switch with 4-channel Serial Server.

The TC3847-1DR is often used by Utilities to connect substation RTUs/PLCs, including older legacy units with serial interfaces, to a central control center. Optional Dual-Master Mode adds redundancy, enabling two different hosts to poll remote slave units at the same time.
