ATTENTION

Preventing Electrostatic Discharge

This equipment is sensitive to electrostatic
discharge, which can cause internal damage and
affect normal operation. Follow these guidelines
when you handle this equipment:

Touch a grounded object to discharge potential
static.

Wear an approved grounding wriststrap.

Do not touch connectors or pins on component
boards.

Do not touch circuit components inside the
equipment.

If available, use a static–safe workstation.

When not in use, keep modules in appropriate
static–safe packaging.

This module must be used with a 1771-A1B thru -A4B or later I/O
chassis. Make sure no other output module or single card block
transfer module is placed in the same module group when using
2-slot addressing.

Your module receives its power through the 1771 I/O chassis
backplane from the chassis power supply. The module requires
300mA from the output of this supply. Add this to the requirements
of all other modules in the I/O chassis to prevent overloading the
chassis backplane and/or backplane power supply.

You may select one of two input-failure configurations (last state or
reset) by positioning a configuration plug on the bottom edge of the
printed circuit board. This configuration plug is independent of the
last state switch on the I/O chassis backplane.

To set the fault mode selection, proceed as follows:

1. Locate the fault mode selection plug at the bottom edge of the

module circuit board.

2. Using your finger, slide the plug off the two posts.

3. Carefully position the plug on two of the three posts that

correspond to your requirement.
