Power Supply - Emerson CSI 6500 Machinery Health Monitor A6110 Schnellstartanleitung

Product Information / Produktinformation A6110
Shaft Vibration Monitor

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
Separation
Sensor supply channel 1
Sensor supply channel 2

Max. current
Max. short−circuit current
Two redundant diode decoupled inputs for nominal
+24 V with common 0 V reference
d2 / z2

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.
