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.

Safety Refer to the “FOR YOUR SAFETY” page preceding the Table of
Contents. Follow all NOTES, CAUTIONS, and WARNINGS to
ensure personnel safety and prevent damage to the instrument.
About MTBF The 1260-22 MTBF is 400,255 hours, calculated in accordance
with MIL-HDBK-217E, with the exception of the electromechanical
relays. Relays are excluded from this calculation because relay life
is strongly dependent upon operating conditions. Factors affecting
relay life expectancy are:
1. Switched voltage
2. Switched current
3. Switched power
4. Maximum switching capacity
5. Maximum rated carrying current
6. Load type (resistive, inductive, capacitive)
7. Switching repetition rate
8. Ambient temperature
The most important factor is the maximum switching capacity,
which is an interrelationship of maximum switching power,
maximum switching voltage and maximum switching current.
When a relay operates at a lower percentage of its maximum
switching capacity, its life expectancy is longer. The maximum
switching capacity specification is based on a resistive load, and
must be further de-rated for inductive and capacitive loads.
For more details about the above life expectancy factors, refer to
the data sheet for the relay.
Manufacturer P/N
Siemens T90N1D12-24
Aromat JT1A-DC24V
The relay used on the 1260-22 module is part no. 310269. The
relay manufacturer’s specifications for this relay are:

Electrical 105 operations (Full Load resistive)
For additional relay specifications, refer to the relay manufacturer’s
data sheet.

INSTALLATION INSTRUCTIONS
Unpacking and
Inspection 1. Remove the 1260-22 module and inspect it for damage. If any
damage is apparent, inform the carrier immediately. Retain
shipping carton and packing material for the carrier’s
inspection.
2. Verify that the pieces in the package you received contain the
correct 1260-22 module option and the 1260-22 Users Manual.
Notify EADS North America Test and Services, if the module
appears damaged in any way. Do not attempt to install a
damaged module into a VXI chassis.
3. The 1260-22 module is shipped in an anti-static bag to prevent
electrostatic damage to the module. Do not remove the module
from the anti-static bag unless it is in a static-controlled area.

Installation Instructions 2-2 EADS North America Test and Services
Module
Configuration The 1260-22 is a 40-channel single wire module consisting of 40
individual SPST relay switches. Refer to Figure 2-2 for a block
diagram of the 1260-22. This single relay architecture permits the
1260-22 module to be organized via software in any configuration
from 40 – SPST’s to 1 - 40PST or any combination thereof (by use
of the include command) without the use of hardware jumpers.
This is the same as being automatically configurable as a 1-wire,
2-wire, … n-wire switch.
In addition, by using internal jumpers, the user can configure the
module as a SP2T, SP3T, etc., up to a SP40T switch (i.e. a
multiplexer).
The 1260-22A is a standard configuration of the 1260-22 which
uses internal jumpers to configure the module as 5 - 4x1
multiplexers and 10 - 2x1 multiplexers. Refer to Figure 2-3 for a
block diagram of the 1260-22A.
Provision is made on the PCB to add contact protection devices
such as MOV’s or snubbers to each of the relay channels if the
relay contact load is inductive. Some suggested devices include a
Phillips Components P/N 2322-594 Series of varistors. Refer to
Figure 2-1, for a 1260-22 typical Module Relay Channel.
