Installation Instructions
FlexArmor Analog Output Module
Catalog Number 1798-OE2
43000
The FlexArmor I/O module (Cat. No. 1798-OE2) mounts in a
FlexArmor Baseplate. Use compatible sealed cordsets to connect all
field side wiring. All cordsets must be shielded to achieve proper
noise immunity.
The 1798-OE2 module provides connections for up to 2 single ended
non-isolated outputs. This module has two 12 mm connectors
configured for analog output. A diagnostic feature for this module
includes sensor power short-circuit detection. The outputs can be
either voltage or current.
Package Contents
Your package contains one FlexArmor 1798-OE2 module and these
installation instructions. (Note: Baseplates and other components are
ordered and shipped separately.)

Environment and Enclosure
This equipment is intended for use in a Pollution
Degree 2 industrial environment, in overvoltage
Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000
meters without derating.
This equipment is considered Group 1, Class A
industrial equipment according to IEC/CISPR
Publication 11. Without appropriate precautions,
there may be potential difficulties ensuring
electromagnetic compatibility in other
environments due to conducted as well as
radiated disturbance.
This equipment is supplied as "enclosed"
equipment. It should not require additional
system enclosure when used in locations
consistent with the enclosure type ratings stated
in the Specifications section of this publication.
Subsequent sections of this publication may
contain additional information regarding specific
enclosure type ratings, beyond what this product
provides, that are required to comply with
certain product safety certifications.
See NEMA Standards publication 250 and IEC
publication 60529, as applicable, for
explanations of the degrees of protection
provided by different types of enclosure. Also,
see the appropriate sections in this publication,
as well as the Allen-Bradley publication 1770-4.1
("Industrial Automation Wiring and Grounding
Guidelines"), for additional installation
requirements pertaining to this equipment.

Install the Module into the Baseplate
For instructions on how to mount the FlexArmor Baseplate, refer to
publication no. 1798-IN003.
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, store the equipment in
appropriate static-safe packaging.
To install the module into the Baseplate:
Publication 1798-IN009A-EN-P - April 2002
1. Hold the module at an angle and engage the top of the
module in the indention on the rear of the Baseplate.
2. Press the module down flush with the panel until the locking
lever locks.
3. Repeat these steps for each I/O module and each remaining
Baseplate I/O slot.
I/O modules can be installed in any slot location
to the right of the adapter module. The adapter is
capable of addressing up to eight I/O modules.

4. Screw down the module retaining screws to ensure IP67
compliance.
IMPORTANT
• Torque the screws to 0.5-0.7 Nm. (4.43 - 6.2
inch pounds).
• Dust caps must have 4 inch pounds of torque
to maintain IP67 compliance.
Connect the Cordset to the FlexArmor Module
The module uses 5 pin micro (12mm) style PCB mounted connectors.
Two micro caps cover the I/O connectors on the module. Remove
the caps and connect your cables to the appropriate ports. Keep the
caps in place on any unused connector to maintain the IP67 rating.
A pinout diagram for the connectors is shown below.

ATTENTION
!
• Make sure all connectors and caps are
securely tightened to properly seal the
connections against leaks and maintain IP67
requirements.
• For maximum noise immunity, input and
output cable return wires must be properly
terminated. When inputs and outputs are
connected in loopback, return wires should
be connected together.
• I/O cable length should be less than 30
meters.
