The CIO-DIO48 can control 48
devices or sense 48 contact
closures from a single half-size
card in a pc. The CIO-DIO48
employs two 8255 parallel
peripheral interface chips which
are pro-grammable in three modes;
simple byte input or output or
strobed I/O. The 8255 is simple to
program. The CIO-DIO48 can
provide 2.5 mA to activate other
chips, but not enough for LED’s or
relays. The CIO-DIO48H can source
15 mA or source 64 mA, enough for
switching most relays and SSR’s.
Each 8255 has 24 I/O lines. The
chip is configured as three ports.
Two ports, A & B, are 8-bits wide,
while port C may be an 8-bit port or
two 4-bit ports. Individual ports may
be configured as input or output,
and are written to or read from
as a unit.
The CIO-DIO48 is a member of a
family of digital I/O boards which
use a 50-pin connector. Applications
can easily be sized from 48 to 192
digital I/O points or more. Software
is extensible to multiple points and
all the accessories, including screw
terminal boards, electro-mechanical
relay boards and solid state relay
boards interface to the same
connector, regardless of which
digital I/O board is used.
Base Address
To program and control the DIO board,
the PC writes to and reads from the I/O
address assigned to the board. The DIO
boards’ address is set by selecting a
base address via the base switch.
Cabling and Connection
Cabling to the CIO-DIO48 is via
standard 50-pin, 0.10" spacing AMP
type ribbon cable connectors. Each
cable carries 48 digital I/O lines, +5 V
and ground.

The CIO-MINI50 provides 50 12
to 22 AWG screw terminals. The
CIO-SPADE50 provides terminals for
50 spade type connections.The
SSR-RACK24 mounts 24 solid state
relays, and the CIO-ERB24 mounts
24 electro-mechanical relays.
