R8-PS1

Remote I/O R8 Series

EXTENSION POWER SUPPLY MODULE
(non-isolated)

Functions & Features
• Inserted between I/O modules and supply the power
• Up to two R8-PS1 use is available

MODEL: R8–PS1-R[1]

ORDERING INFORMATION

SPECIFICATIONS OF OPTION: Q
COATING (For the detail, refer to M-System's web site.)
/C01: Silicone coating
/C02: Polyurethane coating

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
