2.3.2 Power Supply
The X-600 expansion bus normally provides both power and communications to the expansion modules.
This method however, is not workable with the X-18s because it has large relays and the ribbon cable
cannot reliably provide sufficient DC power. Instead the X-18s has two dedicated screw terminal
connections for making direct connections to a 9 to 28VDC power supply. It is recommended to connect
these two terminals to the same power supply that powers the X-600M master. The 10-pin ribbon cable
has connections which allow the X-600M to power X-11s, X-12s etc modules. These power connections
flow thru the X-18s from one ribbon cable connector to the other, but are not connected to its internal
power supply.
