Power Supply - Emerson CSI 6500 Machinery Health Monitor Schnellstartanleitung

Product Information / Produktinformation A6120
Bearing Vibration Monitor
Interface RS 485
d4, z4 bus interface for communication with an MMS 68xx epro analysis and diagnostic
system and the configuration software.

1.6.5 Power supply

The monitor system voltages, and thus the 0 V / common connections for the measurement
and monitoring inputs and outputs, are galvanically separated.
Supply voltage inputs
Voltage input UB+ / UN+
Common reference 0 V U−
Perm. voltage range
Power consumption
Monitor system voltage
The system voltages required for the internal supply are constantly monitored on overvoltage.
If undervoltage is detected an error message is generated.
Sensor supply
For both channels of the monitor, as lifting current for seismic sensors or as supply current for
charge amplifiers.
Separation
Lifting current channel 1
Lifting current channel 2
Current setting
Tolerance
Two redundant, diode decoupled inputs for nominal
+24V with common 0V reference
d2 / z2
b2
19 ... 31.2Vdc (IEC 654−2 class DC 4)
CSA: 24Vdc; SELV LPS
max. 6 W, at 24 V max. 250 mA
Decoupled and galvanically separated from the
supply voltage,
can be operated in parallel with other monitors, open
circuit and short circuit proof, non reactive.
