Product Information / Produktinformation A6150
Bearing Vibration Monitor
Interface RS 485
d4, z4 bus interface for communication with an MMS 68xx interface card and an analysis or
diagnostic system and the configuration software.
1.7.5 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
The sensor LF−24/0.3Hz requires an external +/−15V DC voltage supply, e.g: Phoenix Mini−
PS−100−240AC/2X15DC/1.
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
