RANEXPAD Master Port Expander

The

RANEXPAD

is a Master Port Expander that provides additional ports beyond those

available on a

RANEXP

RANEXP

before you can add

RANEXPAD

. Each

RANEXPAD

adds an additional set of 12 runs of cable (with a

maximum of 60,000 pF). It requires 12

VDC

at 200 m

and is mounted in a single rack

space (1.75"). The

RANEXPAD

must be mounted in the same head-end as the

RANEXP
