Note *
2
：
The 5VDC power of 10/14PTs main unit is generated from the 24VDC power in the output circuit, with specifications of
5VDC
±
10% and 400mA (max) (Circuit is located on the I/O board of 10/14PTs main unit).
Note *
3
：
Without any I/O expansion interface, the 24VDC power in 10/14PTs main unit is for its output circuit alone and cannot be
used for other purposes.
Caution
The schematic diagram of AC power supply wiring in main/expansion units is shown below. Also be cautious
about the following:
Please follow the wiring schemes regulated by local national standards to use single-pole switch
（
break hot wire
〝
L
〞
）
, or double-pole switch
（
break both
〝
L
〞
and
〝
N
〞
）
, to turn on or off the AC input power.
In wiring, hot wire
〝
L
〞
must be connected to the L terminal on unit, while the ground line
〝
N
〞
connected to the
N terminal. Please use wires with diameters 1mm
2
～
2mm

.
All G terminals on main unit and expansion unit/module have to be connected to the EG (Earth Ground)
terminal of main power system as shown in the figure below, with wire diameters larger than 2mm

Specifications and Wiring of DC Power Sourced Power Supply
The available DC power sourced power supplies of FB
S
-PLC are the 14 Watt (SPW14-D12/D24) supply for 10/14PTs
main unit, the 24 Watt (SPW24-D/12D24) supply for 20~60PTs main/expansion unit, and the 14 Watt expansion supply
(FB
S
-EPW-D24) for expansion modules. Besides the FB
S
-EPW-D24 is an independent module, SPW14-D12/D24 and
SPW24-D12/D24 are to be installed on a main unit or inside an expansion unit, where their appearances are invisible.
The following table lists the specifications:
Warning
Output of power for sensor cannot be connected in parallel with other powers, in which the conflict between two
sets of power will decrease their lifetime or cause immediate damage. This will induce unexpected malfunction of
PLC and cause serious or even deadly damage to people or equipment.
