Preinstallation Considerations

This document provides information on:

• important pre-installation considerations

• power supply requirements

• installing the module

• using the module indicators for troubleshooting

• replacing a fuse

• module specifications

An output from this module can drive an Allen-Bradley Size 5 motor starter, provided its supply voltage does not drop below 92V ac. The maximum load current the module can deliver is 2A per channel, not to exceed 8A total per module.

Your module’s outputs can drive the following motor starter combinations:

• 16 size 3 motor starters (1 per output)

• 10 size 4 motor starters (1 per output)

• 7 size 5 motor starters (1 per output)

The switching device in the output circuit is a solid-state triac. There is a small leakage current in the off state due to both triac and capacitive characteristics. The maximum leakage current per output is 3mA at 138V ac. Nominal leakage current is 1.5mA. The on-state voltage drop across the output terminals will not exceed 1.5V ac at 2A.

The 1771-OD16/B module is designed for a 5mA minimum current on each output circuit. The total continuous current the module supports is 8A (2A maximum per channel).

ATTENTION: If the 8A maximum per module (2A per module) rating is exceeded, the module overheats

The module uses zero voltage turn-on to reduce the electromagnetic interference and high inrush currents during initial turn-on. This zero crossing feature switches line voltage only when it is close to zero. The typical value for zero crossing voltage is +

and damage may occur.

Publication 17715.21 -February 1997

AC (120V) Isolated Output Module, 16 Outputs2

This module can be used in all 1771 I/O chassis except the 1771-A1,

-A2 or -A4 chassis. It may also be used in a 1771-AM1 or 1771-AM2 chassis.This module is not compatible with the 1771-AL local I/O adapter module.

Suppression

Surge suppression circuitry is provided for the output triacs in this module. To suppress high-voltage transients from the AC line, a metal-oxide varistor (MOV) is provided between each set of terminals on the module. In each output circuit an RC network limits the magnitude of voltage transients that may occur when a device is wired in parallel or series with hard contacts.

Loads with inductive characteristics may require additional suppression devices. The impedance characteristic of the load is the most important factor in selecting a suppression device; thus no single suppression device can be recommended for every possible load. Acceptable suppression devices for typical loads are shown in the table below.

Determining Module Placement in the I/O Chassis

You can place your module in any I/O module slot of the I/O chassis except for the left-most slot. The left-most slot is reserved for programmable controller processors or adapter modules. Group your modules to minimize adverse effects from radiated electrical noise and/or heat. We recommend the following:

ATTENTION: Remove power from the 1771 I/O chassis backplane and wiring arm before removing or

installing an I/O module.

• Failure to remove power from the backplane or wir-

ing 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.

• Group analog input and low voltage dc modules away from ac

modules or high voltage dc modules to minimize electrical noise interference.

• Place analog input modules and other I/O modules sensitive to

heat away from slot power supplies to minimize adverse heat effects.

Initial Handling Procedures

ATTENTION: Remove power from the 1771 I/O chassis backplane and wiring arm before removing or

installing an I/O module.

• Failure to remove power from the backplane or wir-

ing 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.

• Touch a grounded object to rid yourself of charge before handling

the module.

• Do not touch the backplane connector or connector pins.

• When you configure or replace internal components, do not touch

other circuit components inside the module. If available, use a static-safe work station.

• When not in use, keep the module in its static-shield bag.

Setting the Mode of the FuseBlown Jumper

The fuse-blown jumper has two modes:

• the preset, standard (STD) mode – displays the fuse status on

the red fuse-blown status indicator

• the customer side indication (CSI) mode – displays the fuse

status in the input image table and on the red fuse-blown status indicator. This mode configures the module as a 16 point output module that utilizes both the output and input image data tables of your controller. When a fuse blows, all 16 bits in the associated input image table will turn on (1).

For

example,

as O:012, then the fuse status bits are in I:012.

To monitor the status of the module fuses, make certain that your user program monitors the module’s input image table for ‘‘on” bits.

if you install the module in a PLC5 system and address the module

ATTENTION: Do not put the module jumper in CSI mode when you use this module in a complementary mode. Your system will not operate properly.

Note: You can use the shorting bar to connect the L1-0 through L1-17 high side ac power connections together if no isolation is

required.

You can use an output of the 1771-OD16 module to drive an input of a 120V ac input module (1771-IA, -IA2, -IAD,-ID or ID16), as shown below, to indicate status of turning on a motor starter, for example. Inputs configured with the output module are not isolated from each other.

ATTENTION: Do not connect the 1771-OD16 output channels in series. Doing so can result in

distortion of the output waveform causing the output devices to chatter.

Interpreting the Status Indicators

The module has 18 indicators (below), consisting of 16 output status indicators, an active indicator and a fuse blown indicator. The 16 status indicators will light when an ”on” signal has been communicated between the module and the system backplane.

The ACTIVE indicator will light when the module has started up and successfully initialized.The FUSE blown indicator will light when the fuse has cleared or been removed and the channel associated with that fuse has been turned ”on.” The fuse-blown circuit will not operate if the applied voltage to that channel is above the specified minimum ”on-state” voltage, and the output load current is less than or equal to 5mA. The FUSE blown indicator will reset after the fuse has been replaced and chassis power has been cycled.

Replacing a Fuse

Each module output is individually fused. You can easily access the module fuses through the access holes on the side cover. Follow the procedure below.

ATTENTION: Remove power from the 1771 I/O chassis backplane and wiring arm before removing or

installing an I/O module.

• Failure to remove power from the backplane could

cause injury or equipment damage due to possible unexpected operation.

• Failure to remove power from the backplane or wir-

ing arm could cause module damage, degradation of performance, or injury.

If a blown fuse occurs:

1. Turn off power to the I/O chassis backplane.

2. Pivot the wiring arm away from the module and pull the module

from the I/O chassis.

3. Use a small common screwdriver to reach through the front of the

module and carefully pry one end of the fuse out of its holder.

Reach through hole in side cover and twist and pull to remove fuse.

4. Reach through the access hole on the side of the module and

5. Reinstall the module in the I/O chassis.

6. Reposition the wiring arm.

7. Restart system power.

Pry up on one end of the fuse

to remove it from the holder.
