ATTENTION

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.

AC (120/240V) Output Module4

PreĆinstallation Considerations

The 1771-OAN ac output module is a source output and requires a sink input. A sink input provides a path to ground and a source output provides a positive voltage path.

This module is not compatible with 2-slot addressing. You must use 1-slot addressing with restrictions, or 1/2-slot addressing with no restrictions.

You must use this module in a 1771-A1B thru

IMPORTANT

-A4B or later 1771 I/O chassis. Refer to the Table below for processor compatibility.

Power Supply Requirements

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 800mA.

Initial Handling Procedures

ATTENTION

AC (120/240V) Output Module 5

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.

Key the Backplane Connector

Place your module in any slot in the chassis except the leftmost slot which is reserved for processors or adapters.

ATTENTION

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.

Position the keying bands in the backplane connectors to correspond to the key slots on the module.

I/O chassis

You can change the position of these bands if subsequent system design and rewiring makes insertion of a different type of module necessary.

Place the keying bands:

between 16 and 18 between 22 and 24

Install the Module and Field Wiring Arm

ATTENTION

Remove power from the 1771 I/O chassis backplane and field wiring arm before removing 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.

Snap the chassis latch over the top of the module to secure it.

Attach the wiring arm (1771ĆWN) to the horizontal bar at the bottom of the I/O chassis.

The wiring arm pivots upward and connects with the module so you can install or remove the module without disconnecting the wires.

Connecting Wiring to the Module

You make 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

Turn the power to the chassis off before connecting or disconnecting any wiring. Turn off power to the I/O chassis before inserting the module into the chassis.

• Failure to remove power from the backplane

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.

1. Make certain all power is removed from the module before making wiring connections.

2. Swing the wiring arm up into position on the front of the module. The locking tab on the module will secure it into place.

3. Make your connections to the field wiring arm as shown in the connection diagram. (Use the label on the front of the wiring arm to identify your 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 = outputs 00 through 17

Module group 2 = outputs 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 1, 11, 21 and 31 are ac high (L1).

Interpreting the Status Indicators

Replacing the Fuses

The module has 32 status indicators on the module front plate. These represent the control status of the outputs. Each indicator is lit when its corresponding output is energized.

Status Indicators (red)

11853ĆI

Each group of eight outputs share a common fuse. To replace a blown fuse, proceed as follows:

ATTENTION

Remove power from the 1771 I/O chassis backplane and field wiring arm before removing 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.

1. Turn off power to the chassis.

2. Remove the module from the I/O chassis.

3. Remove the blown fuse from the fuse holder (accessible through

the side cover), and replace it with a 4A, 250V normal blow fuse.

4. Reinsert the module into the I/O chassis.

5. Turn on power to the chassis.
