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.
