Most digital I/O boards can not
be directly interfaced to real world
devices. Output voltages are usually
limited to TTL levels (0/5 Vdc) with
a few milliamps of drive current.
Inputs are also typically limited to a
maximum 5 volt level. When higher
voltages or currents are needed,
OMEGA's solid state I/O modules
are the perfect solution. Models are
available for input or output signals
in AC and DC voltage versions.
The SSR-RACK series is a family
of backplanes that accept the solid
state I/O modules and provide
a direct connection to OMEGA's
CIO family of digital I/O PC plug-in
boards. Three models are available;
the SSR-RACK48, SSR-RACK24
and SSR-RACK08 which are 48, 24
and 8 channel models respectively.
SSR-RACK48
The SSR-RACK48 is a high density
mounting and interface rack for the
quad type solid state I/O modules
(OMEGA's SSS-Q series). The
rack can hold 12 quad modules
for a total of 48 channels of I/O.
The SSR-RACK48 provides screw
terminals for field connections.
The connection to the digital I/O
board is made through a 50 pin
connector. The SSR-RACK48 may
be connected directly to the CIODIO192, CIO-DIO96 and CIO-DIO48
using a C50FF-2 cable.
SSR-RACK24
The SSR-RACK24 accepts 24
of OMEGA's single channel SSS
series solid state I/O modules.
Screw terminals for each module
provide field connection. The SSRRACK24 contains both a 37 pin
and a 50 pin connector. The 37 pin
connector is designed to interface to
24 channel I/O boards. The 50 pin
connector is used to connect to
I/O boards with 48 channels or
greater. A second 50 pin connector
is provided so additional SSRRACK24s may be connected to the
same digital I/O board.
The SSR-RACK24 may be
connected directly to the CIO-DIO24,
CIO-DIO24H and CIO-DIO24/CTR3
digital I/O boards using the C37FF-2
cable. The SSR-RACK24 may be
directly connected to the
CIO-DIO192, CIO-DIO96 and the
CIO-DIO48 boards using the
C50FF-2 cable.
SSR-RACK08
If your application needs only a
limited number of solid I/O modules,
you can save money and cabinet
space with the SSR-RACK08. It
holds 8 single function solid state
relays and is cabled to Port C of
the digital I/O board so that you can
split the 8 relays between input and
output. The SSR-RACK08 uses a
37 pin connector and can connect
directly to a CIO-DIO24, CIODIO24H or CIO-DIO24/CTR3 with
a C37FF-2 cable.

high voltage is applied to an input
module, the output of the SSRRACK will go low (ground). When
a low voltage is applied to an input
module, the output of the SSRRACK will be a high signal (5V).
Output modules also use inverted
logic. This means that a 0 output
from the digital I/O board will
cause an output module to activate

SSR-RACKs Have Buffers on Board
Most 8255 based digital I/O boards
do not provide enough output
current to directly turn on a solid
state I/O module. The SSR-RACKs
are designed with buffers on board.
That means you can plug directly
into the SSR-RACK from your CIODIO24, 48, 96 or 192 or any other
82C55 based digital I/O board.
