MULTIPLE I/O TERMINAL
Section 1-1

Features
Simple Connections
The Communications Unit and the I/O Units are separate, and the Communi-
cations Unit and the I/O Units are connected by an I/O Unit interface. I/O can
be expanded simply by connecting additional I/O Units to the I/O Unit inter-
face.
Automatic Recognition of
I/O Units
When the power to the Communications Unit is turned ON, the models of the
I/O Units on the I/O Unit interface are automatically recognized, and the num-
ber of remote I/O communications points with the DeviceNet Master Unit is
automatically determined. This enables I/O to be increased or decreased sim-
ply by connecting or disconnecting I/O Units.
Status Notification
Status information about the I/O Unit interface can be transmitted as inputs to
the DeviceNet Master Unit (two words).
Many Types of I/O Unit
The following I/O Units are available.
• 16- or 32-point Transistor Input Units (terminal block, connector, 25-pin D-
sub connector, or high-density connector)
• 16- or 32-point Transistor Output Units (terminal block, connector, 25-pin
D-sub connector, or high-density connector)
• 8-point/16-point Relay Output Unit (16-point Unit)
• 4- or 8-point Analog Input Unit (terminal block or connector)
• 4-point Analog Output Unit (terminal block or connector)
• 1-point Pulse Input Unit (high-speed counter)
• 4-point Temperature Input Unit
An I/O-intensive System
Can be Built at Low Cost
Compared with fixed I/O Terminals, a high cost-performance ratio can be
achieved if I/O Units are used.
Range Setting by
Configurator
The input and output ranges for the Analog Input, Analog Output, and Tem-
perature Input Units can be set for each point using the Configurator (with ver-
sion 1.11 or later). Using DIP switches, ranges can be set in 2-point units for
the Analog Input and Analog Output Units, and in 4-point units for the Temper-
ature Input Unit.
