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)

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 LED: Green light 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

•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.)
