August 6, 2013 - TC Communications announces TC8928 Analog Broadcaster/Bridge. It receives a single 2/4-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. For SCADA applications, the TC8928 can be used with legacy analog SCADA computers to enable the incoming 600 ohm analog signal to be broadcast out to multiple sites or Remote Terminal Units (RTUs) and then allowing only one site to respond back to the host port. In many instances, users can use the TC3846-6 Analog IP Gateway so they can run the analog signal over Ethernet.
The Analog Broadcaster/Bridge 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. High and extreme temperature versions (-20°C to70°C & -40°C to 80°C) are available for harsh environments.
