Number of connectable units
● When the basic unit is a KV-10xx/16xx/24xx
Up to four input units and four output units (that is, up to 8 total expansion units)
can be connected to one basic unit.
● When the basic unit is a KV-40xx
Up to three input units and four output units (that is, up to 7 total expansion units)
can be connected to one basic unit.
● When KV-E4XT/KV-E4XR expansion I/O units are connected
One I/O unit is regarded as two units (that is, one input and one output unit). For
example, when only expansion I/O units are connected to one basic unit, up to
four expansion I/O units can be connected. Up to three expansion I/O units can
be connected to a KV-40 xx basic unit.
Note 1: There are no restrictions about the order of connected expansion units.
Note 2: When connecting expansion units to an AC power type basic unit, be sure
that the total current consumption of all connected units does not exceed the output
capacity of the Visual KV Series basic unit. Otherwise, consider to use a DC power
type basic unit in conbination with an external DC power supply having enough
capacity.
