Frequency Distribution Unit
The IBU-240 Frequency Distribution Unit offers the user modern, often requested and reliable time code distribution features.
- Wide input bandwidth
- Input isolation
- Automatic & manual changeover unit
- Transformer coupled outputs
- 24 outputs
- Front panel status indicators
- Fault discrete inputs
- Compact, 1U, 19” rack mount
The base unit outputs 24 time code outputs that are transformer-coupled from the rear panel connectors to the transfer switch.
Each output is a faithful reproduction of the time code input A 3-position front panel switch chooses automatic operation or may be used to manually select one of the two input sources.
When the AUTO mode is selected the AUTO indicator will be illuminated and Input A will be used if it is available. Should Input A fail, Input B will be chosen automatically.
Indicators show the status of the inputs and which input has been selected. Each of the 24 outputs is monitored. Should an output fail a group alarm, the Fault indicator will illuminate.
A front panel Power indicator is also provided. The IBU-240 is packaged in a lightweight, 1U chassis complete with an integral power supply Rear panel input Fault Discrete signals allow external equipment to force the outputs to be derived from either input source.
Applications for the IBU-240 include reliable signal distribution in systems designed for satellite ground stations, secure military communications and range timing.
