SDU-R: Redundant Frequency Sine or TTL Distribution Unit

The SDU-R is a distribution unit, designed to provide sine wave signals with low additive phase noise, TTL output signals via BNC female connectors or fiber optical signals via F-ST connectors on the system's rear panel.

In addition, a redundant power supply can be used for the respective application via various power supply modules. The signal distributor is used in areas where high reliability of the output signals is required.

Key Features

16 outputs in an 1U chassis
Internal switchover, 2 Error inputs and alarm relay
Status LEDs of power supplies and switch card (selected input source, remote function, initialisation)
Compact 1U housing, 19-inch rack mount option
Redundant input signal and power supplies

Product Description

The SDU-R/SIN/NET/RPS distributes the input signals, which is provided to one or both inputs. If the unit is used in redundant mode, the internal decision logic, monitors both signals and chooses one input for distribution automatically.

The input signal can also be selected manually with the switch on the front panel.

The monitor programm Meinberg Device Manager, shows the level of all inputs and outputs, status of the power supplies and the internal system temperature.
