Specifications And Wiring Of Ac Power Sourced Power Supply - FATEK FBs Series User Manual

Chapter 5 Power Supply Wiring, Power Consumption
Calculation, and Power Sequence Requirements
FB -PLC internally has three kinds of circuit: a 5VDC logic circuit, a 24VDC driver circuit (driver output devices, for
S
example: relay, transistor, and etc), and a 24VDC input circuit. Only the 5VDC logic circuit and 24VDC output circuit
are powered by the built-in power supply for main/expansion units or powered by expansion power supply modules
(FBs-EPW-AC, FBs-EPW-D24), and the 24VDC input circuit can be choose to powered by the external power supply
or the built-in power supply of main/expansion units or 24VDC sensor of FBs-EPW-AC/D12/D24. Expansion modules
other than main/expansion units do not contain any power supply and are powered by the power supply inside the
main/expansion units or expansion power supply (FB
power supply with their model numbers suffixed with "-D12/-D24" means is operated by DC power source. Otherwise,
AC power source is used.
In industrial environments, main power may irregularly experience a surge current or high voltage pulse
caused by the start or shut down of high power equipment. Users are advised to take necessary
measures (for example, the use of isolation transformer or other MOV suppression devices) for the
protection of PLC and its peripherals.
