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 “open type”
equipment. It must be mounted within an
enclosure that is suitably designed for those
specific environmental conditions that will be
present, and appropriately designed to prevent
personal injury resulting from accessibility to live
parts. The interior of the enclosure must be
accessible only by the use of a tool. Subsequent
sections of this publication may contain additional
information regarding specific enclosure type
ratings 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 enclosures. 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.

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.

or installing an I/O module.
Failure to remove power from the backplane or
wiring arm could cause module damage,
degradation of performance, or injury.
Failure to remove power from the backplane
could cause injury or equipment damage due to
possible unexpected operation.
!
ATTENTION
A module inserted into a wrong slot could be
damaged by improper voltages connected through
the wiring arm. Use keying bands to prevent
damage to the module.
Place your module in any slot in the chassis
except the leftmost slot, which is reserved for
processors or adapters.
Observe the following precautions
when inserting or removing keys:
insert or remove keys with your
fingers
make sure that key placement is
correct
Incorrect keying or the use of a tool
can result in damage to the
backplane connector and possible
system faults.
!
ATTENTION
Position the keying bands in the backplane connectors to correspond to
the key slots on the module.
You can change the position of these bands if
subsequent system design and rewiring makes
insertion of a different type of module necessary.

The 1771–OVN module is a modular component of the 1771 I/O
system requiring a properly installed system chassis. Refer to
publication 1771–IN075 for detailed information on acceptable

disconnect the wiring arm with field power
applied, an electrical arc can occur. This could
cause an explosion in hazardous location
installations. Be sure power is removed or the area
is nonhazardous before proceeding.

WARNING
When you connect or disconnect the wiring arm
with field power applied, an electrical arc can
occur. This could cause an explosion in hazardous
location installations. Be sure power is removed
or the area is nonhazardous before proceeding.

or installing an I/O module.
Failure to remove power from the backplane or
wiring arm could cause module damage,
degradation of performance, or injury.
Failure to remove power from the backplane
could cause injury or equipment damage due to
possible unexpected operation.
Make wiring connections to the module through the field wiring arm
cat. no. 1771-WN. The arm pivots on the I/O chassis to connect with
terminals on the front of the module and acts as a terminal strip. The
wiring arm allows the module to be removed from the chassis
without disconnecting wiring.
!
ATTENTION
The field wiring arm terminal identification
number is not the same as the number of the bit
which controls that output.
I/O Module Groups
Each module condenses two full module groups (32 outputs) into
each I/O chassis slot. For example:
Module group 1 = inputs 00 through 17
Module group 2 = inputs 00 through 17 (module group 2
represents the second set of outputs).
Terminals 1 through 20 represent module group 1. Terminals 21
through 40 represent module group 2. Terminals 10, 20, 30 and 40
are DC common and terminals 1, 11, 21 and 31 are DC power.
