Prevent Electrostatic Discharge
Special Conditions for Safe Use
ATTENTION: 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.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in use.
ATTENTION:
• This product is grounded through the DIN rail to chassis ground. Use zinc
plated chromate-passivated steel DIN rail to assure proper grounding. The use
of other DIN rail materials (for example, aluminum or plastic) that can corrode,
oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately. Be sure to ground the DIN rail
properly. Refer to Industrial Automation Wiring and Grounding Guidelines,
publication 1770-4.1, for more information.
• Do not remove or replace an Adapter Module while power is applied.
Interruption of the backplane can result in unintentional operation or
machine motion.
• Do not remove or replace a terminal base unit while power is applied.
Interruption of the backplane cab result in unintentional operation or
machine motion.
• If this equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.

Rockwell Automation Publication 1794-IN083D-EN-P - July 2018 7
FLEX I/O Digital Input and Output Modules
Electrical Safety Considerations
WARNING:
• When you insert or remove the module while backplane power is on, an
electric arc can occur. This could cause an explosion in hazardous
location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
Repeated electric arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance that
can affect module operation.
• If you insert or remove themodule while backplane power is on, an electric arc
can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
WARNING: If you connect or disconnect wiring while the field-side power is on,
an electrical arc can occur. This could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is nonhazardous
before proceeding.
ATTENTION:
• This equipment is certified for use only within the surrounding air temperature
range of 0…55 °C (32…131 °F). The equipment must not be used outside of
this range.
• Use only a soft dry anti-static cloth to wipe down equipment. Do not use any
cleaning agents.
At the end of its life, this equipment should be collected separately from any
unsorted municipal waste.

Fusing
Module outputs are not fused.
Fusing is recommended. If
fusing is desired, you must
supply external fusing. Use SAN-
O MQ4-3A or Littelfuse 235-003
fuses.
Outputs are electronically
protected
(1) Input off-to-on filter time is the time from a valid input signal to recognition by the module. Input on-to-off filter time is
time from the input signal dropping below the valid level to recognition by the module.
(2) Output off-to-on or on-to-off delay is the time from the module issuing an output on or off until the output actually turns
on or off.
