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 Two redundant diode decoupled inputs for nominal
+24 V with common 0 V reference
Voltage input UB+ / UN+ d2 / z2
Common reference 0 V U−
b2
Perm. voltage range 19 ... 31.2Vdc (IEC 654−2 class DC 4)
CSA: 24Vdc; SELV LPS
Power consumption max. 6 W, at 24 V max. 250 mA
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 Decoupled and galvanically separated from the
supply voltage,
can be operated in parallel with other monitors, open
circuit and short circuit proof, non reactive.
Sensor supply channel 1 SENS1− / SENS1+ b6/z6
Sensor supply channel 2 SENS2− / SENS2+ b8/d6
supply voltage 26.75 V DC; Tolerance ±2 %
Residual ripple < 20 mVss (at nominal current 20 mA)
Max. current 35 mA
Max. short−circuit current 0 mA ≤ I short−circuit ≤ 5 mA;
