MODEL: R30EBS
Remote I/O R30 Series

CAUTION

INSTALLATION BASE (R3 I/O module extension use)

• The internal bus communication period for R3 series I/O
modules installed on the R30EBS is as follows.
Internal bus communication period = 6 msec. × number ofI/O module + 10 msec. (Data update period of main CPU)
Example: Four R3 I/O modules
6 msec. × 4 + 10 msec. = 34 msec.
Even when the R30EBS is mounted to the R30BS, theinternal bus communication period of R30 series is kept toapprox. 1 msec.

MODEL: R30EBSMOUNTING REQUIREMENTS unit: mm [inch]■ MOUNTING DIRECTION

The unit must be mounted on a vertical panel. Mounting in any other angle will cause internal temperature to rise,
may shorten the product’s life expectation or deteriorate its performance.
UPDOWN■ MOUNTING ON CONTROL PANEL
Secure sufficient ventilation space. Do not mount the unit right above devices
which radiate great heat such as heaters, transformers or resistors.
Maintenance space is also required above and below the unit.
