The Brandywine Communications Model PDU-240 is a high output count and high performance digital pulse distribution amplifier.
The PDU-240 provides 24 output channels of a single reference pulse, typically 1 PPS, IRIG DCLS or Have Quick time code.
The PDU-240 may be configured either as a dual input distribution amplifier with automatic or manual selection, or two independent 12 channel distribution amplifiers fed from two separate sources.
Features:
- Dual inputs with manual or automatic switchover
- 24 individually buffered outputs
- Pulse rates from 1ppm through 10MPPS available
In the 24 channel, dual input configuration, the PDU- 240 detects failure of either input reference and provides manual or automatic switchover between the two input pulse reference sources.
The PDU-240 has 24 individually buffered outputs, featuring with output voltages from 3V through 10V available.
Output impedance is user selectable for ease of integration.
Power supply options include 115/230 VAC, 48, 24, or 12 VDC.
The PDU-240 is configured as a 1U 19” rack mount unit. Optional rack mount slides are available.
