2. Basic Design and Function Design
The first thing to do in STARDOM engineering is to check whether a given
customer specification can be implemented using the hardware, application
programming tools, APPFs (application portfolios), and licenses provided
with the system.
2.1 Checking Hardware Specification
Review specifications for the hardware given in GS and IM documents to
confirm whether specification requirements are achievable.
2.1.1 Current Consumption of FCN-500 and FCN-RTU Unit
Calculate the current consumption of each FCN unit, and check that it does not
exceed the rated output current of the power supply module.
● Rated Output of Power Supply Module
The rated output current of the FCN-500 power supply module is given by:
System power supply: 0 A to 7.8 A
Analog field power supply: 4 A (max)
SEE ALSO
Chapter A1.3, “Power Supply Module” of IM “STARDOM FCN/FCJ Guide”
The rated output current of the FCN-RTU power supply module is given by:
NFPW426: System power supply: 0 A to 2.4 A
Analog field power supply: 0.54 A (max)
NFPW441: System power supply: 0 A to 7.8 A
Analog field power supply: 4 A (max)
SEE ALSO
Chapter A2.3, “Power Supply Module (NFPW426, NFPW444)” of IM “STARDOM FCN/FCJ Guide”
The power supply module mounted on a unit supplies power only to that unit so
the current consumption of each unit must be kept below the rated output
described above.
