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.

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.
