CAUTION
OUTPUT CURRENT & NUMBER OF CONNECTABLE UNIT
It is NOT available to connect 16 of R8-YV4N to
power/network module because of limitation of output
current of internal supply. The max. output current for
internal supply of power/network module is 1.6 A.
The max. consumption current for internal supply of R8-
YV4N is 160 mA.
1.6 (A) < 160 (mA) x 16 = 2.56 (A)
Inserting the R8-PS1 between 10th and 11th R8-YV4N
enables to connect 16 of R8-YV4N.
POWER UP
Turn the power on at the same time as the power/network
module or turn the R8-PS1 on before the power/network
module turned on. If the R8-PS1 is not turned on within 3
seconds after the power/network module is turned on, I/O
modules are not correctly recognized
GENERAL SPECIFICATIONS
Connection
•Power input, excitation supply: Tension clamp (Front Twin
connection)
Applicable wire size: 0.2 - 1.5 mm2
Stripped length: 10 mm
•Internal bus or internal power: Via connector
Max. number of I/O modules: 16
(Max. consumption current of I/O modules: 1.6 A)
Isolation: Internal bus or internal power or power input to
exc. supply to FE1
Power indicator LED: Green LED turns on when the power is
supplied.
INSTALLATION
Power consumption
•DC: Approx. 11 W 24 V DC (@ internal power max. current
1.6 A)
Internal power supply (power supply for I/O module):
• DC power supply: 5 V DC

Excitation supply output (excitation for I/O module)
•DC: 24 V DC ±10 %
•Operational current: 8 A
(From power supply, exitation supply connector, via
connector for internal bus, supplied to each I/O module.
Power output current consumption must be under
operational current.)
