DB-24 Digital I/O Subsystem
Use the DB-24 Digital I/O manifold card, shown in Figure
3, and its associated dc and ac 4-channel I/O modules to
measure and/or control high level ac and dc signals or if
isolation of the digital I/O is required.
4-Channel Solid State Relays
The DB-24 is a 24-channel I/O backplane that supports
the installation of up to six 4-channel, high-density mod-
ules to perform ac input, dc input, dc output, and dc out-
put functions. You install each module into a socketed
position on the DB-24 backplane, where each module
is held in place with two screws, provided with the
module.
All output modules are able to switch up to 3 amps. AC
output modules provide zero voltage turn-on and have
an RC snubber network for increased capability with in-
ductive loads. AC and dc input modules are designed
with filtering on the input and hysteresis for high noise
rejection and transient free “clean” switching. They are
designed so that high voltage transients on the input
will not cause damage to the module. Optical isolation
for the ac and dc input and output module is rated at
4000 V rms input-to-output.
Each module is color-coded by function and the model
number is clearly marked on the module itself. The
channel numbers associated with the module are
printed below the module on the panel and spaces are

Figure 3. DB-24 Digital I/O Backplane
provided to apply colored stick-on dots (supplied) to
match the color coding of the modules (yellow = ac in-
put, black = ac output, white = dc input, and red = dc
output). Note that the four channels corresponding to
one quad module must be configured with either all in-
put channels or all output channels.
Each module on the DB-24 Digital I/O Backplane oper-
ates by negative true logic, in which a low digital voltage
turns on current to the module. Four LEDs on each mod-
ule indicate the status of the I/O channels (the LED lights
when current is turned on).
Each I/O module position has two 5 amp, 250 V rms pico-
fuses protecting the module and wiring from short cir-
cuits. Table II lists the input and output 4-channel
modules available for use with the DB-24 backplane.
