Rockwell Automation 1771-IL INSTL.INSTR.ISOL ANALOG INPUT - Manual (Page 4)

Isolated Analog Input Module 4
Publication 1771Ć5.51 - October 1996
The module has configuration jumpers for determining the input type
(voltage or current) for each input. The module is shipped with the
configuration jumpers positioned for voltage mode. You can
select either voltage or current for each input.
Keythe Backplane
Connector
Place your module in any slot in the chassis
except the leftmost slot which is reserved for
processors or adapters.
ATTENTION: Observe the
following precautions when
inserting or removing keys:
•
insert or remove keys with
your fingers
•
make sure that key placement
is correct
Incorrect keying or the use of a
tool can result in damage to the
backplane connector and possible
system faults.
!
Position the keying bands in the backplane connectors to correspond to
the key slots on the module.
Place the keying bands:
between 10 and 12
between 32 and 34
You can change the position of these bands if
subsequent system design and rewiring makes
insertion of a different type of module necessary.

The module is shipped with each channel set for voltage mode. If
current mode is desired, you must set a jumper on the functional
analog block (FAB) on the module. You can mix voltage mode and
current mode settings.
