Intended for public safety and SCADA communications applications, the new TC8928 Analog Broadcaster/Bridge from TC Communications receives a single 4-wire 600 ohm analog signal and broadcasts it to up to 7 remote analog lines. It can be used in conjunction with the TC3846-6 Analog IP Gateway to broadcast over Ethernet networks.

The TC8928 provides one host port, up to seven analog ports and operates in two modes:

  • In NORMAL mode, channel 1 (host port) can receive all analog signals from channels 2 to 8. The analog signal from channel 1 will be broadcast to all channels 2 to 8; however, the analog signals from channels 2 to 8 can only go to channel 1.
  • In BRIDGE mode, all of the analog signals from all channels 1 to 8 can communicate at the same time.
  • Broadcasts Up to 7 Remote Ports
  • 4-Wire Analog
  • Operates in Normal and Bridge Mode
  • 12VDC Power Supply, Optional 24VDC, -48VDC, 125VDC or 115/230VAC*
  • Built-In Power Redundancy
  • Rackmount or Standalone
  • Hi Temp or Extreme Temp Options

*115/230VAC for Rackmount unit
 115/230VAC with power adapter for  Wallmount unit


Broadcasts single source radio messages to multiple remote audio devices (e.g. radio consoles, speakers & repeaters)

Broadcasts analog SCADA computer signals out to multiple sites or Remote Terminal Units (RTUs) with one site responding back to host

Often used with TC3846-6 IP Gateway to multicast analog signals over Ethernet/IP
