No = Restricted to complementary module placement.
The module receives its power through the 1771 I/O power supply
and requires 1.1A at 5V (5.5 Watts) from the backplane.
Add this current to the requirements of all other modules in the I/O
chassis to prevent overloading the chassis backplane and/or
backplane power supply.
You can place your module in any I/O module slot of the I/O chassis
except for the extreme left slot. This slot is reserved for PC
processors or adapter modules.
!
ATTENTION: Do not insert or remove modules from
the I/O chassis while system power is ON. Failure to
observe this rule could result in damage to module
circuitry.
Group your modules to minimize adverse affects from radiated
electrical noise and heat. We recommend the following.
•
Group analog input and low voltage dc modules away from ac
modules or high voltage dc modules to minimize electrical noise
interference.
•
Do not place this module in the same I/O group with a discrete
high-density I/O module when using 2-slot addressing. This
module uses a byte in both the input and output image tables for
block transfer.
