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.

The Series B 1771-OVN dc output module is a sink output and
requires a source input. A source input provides a positive voltage
path and a sink output provides a path to ground.

You must use this module in a 1771-A1B, -A2B, -A3B, -A3B1,
-A4B or later 1771 I/O chassis. Refer to the table below for
processor compatibility.

Do not place this module in the same I/O chassis as the 1771-IX
thermocouple module. You can use this module in the same chassis
as the 1771-IXE thermocouple module.

The controller or I/O chassis power supply, connected through the
backplane of the I/O chassis, powers the logic circuitry of the output
modules. The maximum current drawn from this supply is 330mA.
