3 Channel I/O Control Card

Item # 1340073


The IOC-3-R 3 Channel I/O Control Card provides gang and individual control
for up to three A/B switch cards. It can be used to link multiple chassis in large
gang switching systems, allowing for simultaneous switching of multi-chassis
systems.

It can be installed along with an IPC-16-R network control card or an IOC-16-R
I/O access card.

A connection is also provided for external power input from the PS-WRI-4 or
similar +24VDC source.

Connections for individual control is made with screw terminal blocks. For gang
systems, connection between control cards is made using 6 wire connection
modular jack cords. ( RJ11 / RJ12 type )

slot from the

left in the rear of the chassis. Install the card with the components facing left. The chassis and cards are keyed
to prevent incorrect insertion. The IOC-3-R may be inserted and removed with the power on (hot
