Keyphasor® TRANSDUCERS

The System Monitor receives input from four Keyphasor® transducers through terminals on the

PIM. Two of the Keyphasor® transducers are available to the monitors within the rack. All four of

the Keyphasor® transducers are available to the Dynamic Data Interface (DDI). Buffered

Keyphasor® signals are also available from the coaxial connectors on the front panel. The System

Monitor also provides short-circuit protected Keyphasor® transducer power.

STATIC DATA BUS BUFFER

The System Monitor multiplexes signals from either the DDM or TDM to select static data

from the monitors. The System Monitor buffers the static data signals sent from the

monitor to the DDM or TDM.

The System Monitor supports the following Bently Nevada data interfaces: Dynamic Data

Manager (DDM), Transient Data Manager® (TDM), Serial Data Interface (SDI), Dynamic Data

Interface (DDI) and Transient Data Interface (TDI). The SDI and DDI are options of the System

Monitor and reside within the System Monitor slot of the rack. DDM, TDM and TDI are external

data interfaces which gain access to the rack through the PIM. There is an external version of the

SDI and DDI which connects to the PIM. For more information about these products consult a

Bently Nevada sales representative.
