| IBU-240 Provides 24 isolated time code outputs. Designed for IRIG B, IRIG A time code outputs |
|
The Brandywine Communications IBU-240 is a dual input to 24 output low frequency distribution amplifier specifically designed for distributing IRIG A and B modulated formats (including IEEE 1344 extensions) in a 1U 19” rack mount chassis. Each of the 24 outputs is transformer coupled and a faithful reproduction of the time code input. Typical input/output levels are 4 VPP with an output impedance of 600 ohms
A three-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 twenty-four outputs is monitored for failure either internally or externally. Should one of the outputs fail, a group alarm Fault indicator will illuminate on the front panel. Rear panel input Fault Discrete signals allow external equipment to force the outputs to be derived from either input source in case of a source failure.
