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 CIO-DIO192, CIODIO96 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 SSR-RACK24s
may be connected to the same
digital I/O board.
The SSR-RACK24 may be connected directly to the CIO-DIO24, CIODIO24H and CIO-DIO24/CTR3
digital I/O boards using the C37FF2 cable.
The SSR-RACK24 may be directly
connected to the CIO-DIO192, CIODIO96 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.
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.

SSR-RACK Inverting Logic
The SSR-RACK follows the industry
standard convention of inverted
logic used by virtually all manufacturers of solid state backplanes.
When a high voltage is applied to
an input module, the output of the
SSR-RACK will go low (ground).
When a low voltage is applied to an
input module, the output of the
SSR-RACK 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
(complete the circuit) while a 1 (TTL
high) will cause the relay to deactivate. The chips that invert the logic
are socketed and may easily be
substituted with chips that do not
invert the logic.
