1.6.5 Communication interfaces

RS 232 interface
Front socket for connecting a laptop / computer for configuration and visualization purposes
Round plug connector on the front
side
RS 485 interface
d4, z4 bus interface for communication with an MMS 68xx epro analysis and diagnostic
system and the configuration software.
1.6.6 Power supply
The system supply voltages with their grounds, the signal inputs and supervision inputs /
outputs are galvanically isolated from each other.
Supply voltage inputs
Voltage input UB+ / UN+
Common reference 0 V U−
Perm. voltage range
Power consumption
The monitor system voltages, and thus the 0 V / common connections for the measurement
and monitoring inputs and outputs, are galvanically separated.
Monitor system voltage
The module system voltages required for the internal supply are permanently checked on low
voltage. If "Low voltage" is detected, an error message will be given.
Mini DIN socket type TM 0508A/6 for parameteriza-
tion cable (included in the operating kit)
Two redundant, diode decoupled inputs for nominal
+24 V with common 0 V reference

19 ... 31.2Vdc (IEC 654−2 class DC 4)
CSA: 24Vdc; SELV LPS
Max. 6 W, at 24 V max. 250 mA
