DISCLAIMER
Buyer acknowledges and agrees that it is responsible for the operation of the goods purchased and should
ensure that they are used properly and in accordance with this document and any other instructions provided
by Seller. Astronics Test Systems products are not specifically designed, manufactured or intended to be
used as parts, assemblies or components in planning, construction, maintenance or operation of a nuclear
facility, or in life support or safety critical applications in which the failure of the Astronics Test Systems
product could create a situation where personal injury or death could occur. Should Buyer purchase Astronics
Test Systems product for such unintended application, Buyer shall indemnify and hold Astronics Test
Systems, its officers, employees, subsidiaries, affiliates and distributors harmless against all claims arising out
of a claim for personal injury or death associated with such unintended use.

FOR YOUR SAFETY
Before undertaking any troubleshooting, maintenance or exploratory procedure, read carefully the
WARNINGS and CAUTION notices.
This equipment contains voltage hazardous to
human life and safety, and is capable of inflicting
personal injury.
If this instrument is to be powered from the AC line (mains) through an autotransformer,
ensure the common connector is connected to the neutral (earth pole) of the power
supply.
Before operating the unit, ensure the conductor (green wire) is connected to the ground
(earth) conductor of the power outlet. Do not use a two-conductor extension cord or a
three-prong/two-prong
adapter. This will defeat the protective feature of the third
conductor in the power cord.
Maintenance and calibration procedures sometimes call for operation of the unit with
power applied and protective covers removed. Read the procedures and heed warnings
to avoid “live” circuit points.
Before operating this instrument:
1. Ensure the proper fuse is in place for the power source to operate.
2. Ensure all other devices connected to or in proximity to this instrument are properly grounded or
connected to the protective third-wire earth ground.
If the instrument:
- fails to operate satisfactorily
- shows visible damage
- has been stored under unfavorable conditions
- has sustained stress
Do not operate until performance is checked by qualified personnel.

Power
Dissipation – TTL The cooling of the Adapt-a-Switch carrier is dependent upon the
chassis into which it is installed. The carrier can nominally
dissipate approximately 100 W. Even with all channels driven to
maximum outputs, up to six 1260-114 TTL plug-ins may be used
together in a 1260-100 without exceeding the maximum allowable
power dissipation of the carrier.
If the 1260-114TTL will be used in conjunction with other cards,
the 1260-114TTL dissipation should be computed and summed
with the total worst-case dissipation of the remaining modules.
For example, a 1260-114TTL module would dissipate the following
energy:
Quiescent power dissipation = 4.25W maximum
Channel dissipation =
[(Vcc – 2.25) * current * 96(# channels energized)] +
[(current)2* (path resistance) * 96(# channels energized)]
Total Power Dissipation = Quiescent + Channel
Assuming all 96 channels are sourcing a maximum current
of 30 mA and a path resistance of 1Ω:
Total power dissipation =
[(5 VDC - 2.25) * 0.030 A * 96] + [(0.030 A)2* (1 Ω) * 96]
+ ( 4.25 W) = 12.25 W at 55°C
This is acceptable power dissipation for an individual plug-in
module. If five additional modules are likewise loaded, then the
overall carrier dissipation is approximately 74
W, which is well
within the cooling available in most commercial VXIbus chassis. In
practice, rarely are more than 25% of the module’s channels
energized simultaneously, and rarely is full rated current run
through every path. Using the 25% rule, the power dissipated by
each plug-in should be no more than 3 W. If all six slots are used
simultaneously, this would amount to a total dissipation of
18Watts.
Additionally, if fewer plug-in modules are used, more power may
be dissipated by the remaining cards. By using a chassis with high
cooling capacity, such as the 1261B, almost any configuration may
be realized.

Dissipation –
CMOS/TTL
The cooling of the Adapt-a-Switch carrier is dependent upon the
chassis into which it is installed. The carrier can nominally
dissipate approximately 100 W. Even with all channels driven to
maximum outputs, up to six 1260-114CMOS plug-ins may be used
together in a 1260-100 without exceeding the maximum allowable
power dissipation of the carrier.
While the cooling of the Adapt-a-Switch carrier is dependent upon
the chassis into which it is installed, the carrier can normally
dissipate approximately 100 W. Care must be taken, then, in the
selection and loading of the plug-in modules used in the carrier.
With the 1260-114CMOS it is not possible to fully load the carrier
with these cards, drive every channel at full load and exceed the
power dissipation capabilities of the Adapt-a-Switch carrier.
If the 1260-114CMOS will be used in conjunction with other cards,
the 1260-114CMOS dissipation should be computed and summed
with the total worst-case dissipation of the remaining modules.
For example, a 1260-
114CMOS module would dissipate the
following energy:
Quiescent power dissipation = 0.75W maximum
Channel dissipation =
[(Vcc – 3.8) * current * 96(# channels energized)] +
[(current)2* (path resistance) * 96(# channels energized)]
Total Power Dissipation = Quiescent + Channel
Assuming all 96 channels are sourcing a maximum current
of 8 mA and a path resistance of 1Ω:
Total power dissipation =
[(5 VDC – 3.8) * 0.008 A * 96] + [(0.008 A)2* (1 Ω) * 96]
+ ( 0.75 W) = 1.7 W at 55°C
This is acceptable power dissipation for an individual plug-in
module. If five additional modules are likewise loaded, then the
overall carrier dissipation is approximately 10
W, which is well
within the cooling available in most commercial VXIbus chassis. In
practice, rarely are more than 25% of the module’s channels
energiz
ed simultaneously, and rarely is full rated current run
through every path. Using the 25% rule, the power dissipated by
each plug-in should be no more than 0.5 W. If all six slots are
used simultaneously, this would amount to a total dissipation of
2.5Watts.
Additionally, if fewer plug-in modules are used, more power may
be dissipated by the remaining cards. By using a chassis with high
cooling capacity, such as the 1261B, almost any configuration may
be realized.
