■Calculating the current consumption of each power supply port
Use each current consumption in the system and the current value of the maximum rated current in the system for the
calculation and check that the current consumption does not exceed the maximum rated current.
• Module power supply current
= (Sum of the module power supply current values of the NZ2GFSS2-32D-S1)
= 230mA  3 modules + 20mA  1 module = 710mA < 8A (maximum rated current to the terminal block for module power
supply and FG (2-piece spring clamp terminal block))
• I/O power supply current
= (total of the input currents of the NZ2GFSS2-32D-S1) + (total of the currents for the internal circuits of the input part) + (total
of the current consumption of external devices) + (total of the currents for the internal circuits of the output part) + (total of the
load currents for the external connection of the output part)
= 6mA  32 points  3 modules + 40mA  3 modules + 100mA  4 points  3 modules +120mA + 100mA  8 points
= 2.816A < 4.5A (maximum rated current of the I/O power supply current)
■Calculation result
This system can be used because each of the module power supply current and the I/O power supply current does not
exceed each maximum rated current.
