ATTENTION: Remove power from the 1771 I/O
chassis backplane and wiring arm before removing or
installing an I/O module.
•
Failure to remove power from the backplane or wir-
ing arm could cause module damage, degradation of
performance, or injury.
•
Failure to remove power from the backplane could
cause injury or equipment damage due to possible
unexpected operation.
•
Group analog input and low voltage dc modules away from ac
modules or high voltage dc modules to minimize electrical noise
interference.
•
Place analog input modules and other I/O modules sensitive to
heat away from slot power supplies to minimize adverse heat
effects.
The isolated output module is powered by the power supply
connected to the I/O chassis backplane. The module requires a
maximum current of 300mA from the +5V dc output of this supply.
Total the current requirements of this module with the other modules
in the I/O chassis to avoid overloading the supply or the I/O chassis
backplane.
The fuse-blown jumper has two modes:
•
the preset, standard (STD) mode – displays the fuse status on
the red fuse-blown status indicator
•
the customer side indication (CSI) mode – displays the fuse
status in the input image table and on the red fuse-blown status
indicator. This mode configures the module as a 16 point output
module that utilizes both the output and input image data
tables of your controller. Each channel has its own image table
bit. When a fuse blows, the corresponding bit in the associated
input image table will turn on (1).
For example, if you install the module in a PLCĆ5 system and address the module
as O:012, then the fuse status bits are in I:012.
To monitor the status of the module fuses, make certain that your
user program monitors the module’s input image table for ‘‘on” bits.

ATTENTION: Do not put the module jumper in
CSI mode when you use this module in a
complementary mode. Your system will not operate
properly.
