Installation

1762 I/O is suitable for use in an industrial environment whe n installed in accord an ce with the se in struction s . Sp e ci fic ally, this equipm en t is in tended for

use in clean, dry environments ( Po llution degre e 2 exceeding Over Vo ltage Cat egory II

(3)

Remove Power

ATTENTION:

circuits or semiconductors if you touch bus connector pins. Follow these guidelines when you handle the module:

Touch a grounded objec t to discharge static potential.

•

Wear an approved wris t-strap grounding de vice.

•

Do not touch the bus connector or connector pins.

•

Do not touch circuit components inside the module.

•

If av ailabl e, use a static-safe work sta tion.

•

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

•

ATTENTION:

this module. When you remove or install a mo dule with power applied, an electrical arc may occur. An electrical arc can cause personal injury or property damage by:

sending an erroneous signal to your system’s field devices ,

•

causing unint ended machine motion causing an explosion in a hazardous environment

•

causing permanent damage to the module’s circuitry

•

Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may cre ate electri cal resistan c e .

Electrostatic discharge can damage integrated

Mounting

ATTENTION:

the module and a ll other e qui pment near t he mo dule is mou nted a nd

wiring is complete. Once wiring is complete and the module is free of debris, carefully remove protective debris strip. Failure to remove strip before operating can cause overheating.

Minimum Spacing

Main ta in s p ac ing from enclosure walls, wireways, adjacent equipment, etc. Allow

50.8 mm (2 in.) of space on all side s for ad eq u at e ventilation, as sho wn:

Note:

1762 expansion I/O ma y be mounted horizontally onl y.

A TT ENTION:

be sure that all debris (metal chips, wire strands, etc.) is kept from

falling into the module. Debris that falls into the module could cause damage when power is applied to the module.

Do not remove protective debris strip until after

DIN Rail Mounting

The module can be mounted us ing the following DIN rails: 35 x 7.5 mm (EN 50 022 - 35 x 7.5) or 35 x 15 mm (EN 50 022 - 35 x 15).

Before mounting the module on a DIN rail, close the DIN rail latch. P res s the DIN rail mounting area of the module against the DIN rail. T he latch will momentarily open and lock into place.

Use DIN rail end anchors (Allen-Bradley part number 1492-EA35 or 1492-EAH35) for vibrati on or s hock environments .

End Anchor

Note:

For environ ments with greater vibration and shock conc erns , use the panel mounting method described below, instead of DIN rail mounting.

Panel Mounting

Use the dimensional template show n below to mount the module. The preferred mounting method is to use two M4 or #8 pa nhead s cre ws per modul e. M3.5 or #6 panhead screws may also be used, but a washer may be needed to ensure a good ground contact. Mounting screws are required on every module.

Note:

Use the pull loop on the connector to disconnect modules. Do not pull on the ribbon cable.

ATTENTION:

In Class I, Division 2 applications, the bus connector must be

•

fully seated and the bus connector cover must be snapped in place.

In Class I, Division 2 appli cations, al l modules must be mounted

•

in direct contact with each other as shown on page 6. If DIN rail mounting is used, an end stop must be installed ahead of the controller and after the last 1762 I/O module.

Field Wiring Connections

Grounding the Module

This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Additional grounding connections from the module’s mounting tabs or DIN rail (if used) are not required unless the mounting surface cannot be grounded. Refer to

ATTENTION:

Be careful when stripping wires. Wire fragments

that fall into a mo dule could cause damage when po wer is applied.

Once wiring is com p lete, ensur e the module is fre e of all metal fragments.

ATTENTION:

Miswiring of the module to an AC power source

will damage the module.

Sinking/Sourcing Inputs - Sourcing/sinking describes the current flow between the I/O module and the field device. Sourcing I/O circuits supply (sourc e) current to sinking field devices. Sinking I / O circuits are driven by a current sourcing field device. Field devices connected to the negative side (DC Common) of the field power supply are sinking field devices. Fi eld devices connected to the posit ive side (+ V) of the field supply are sourcing field devices.

Note: Fi nger-safe cover not sho wn.

Wiring the Finger-Safe Terminal Block

When wiring the terminal block, keep the finger-safe cover in place.

Route the wire under the termina l pressure plate . You can use the strippe d end

of the wire or a spade lug. The termi nals will accept a 6.35 mm (0.25 in.) spade lug. Tighten th e te r m i n al scr ew ma k i n g su r e th e pr essure plate s ec u re s the w ir e .

Recommended torque whe n tightening terminal s crews is 0.904 Nm (8 in-lbs).

Note:

If you need to remove the finger-safe cover, insert a screw driver into one of the square wiring holes and gently pry the cover off. If you wire the terminal bloc k with the finger-s afe cover removed, you will not be able to put it back on the t erm inal block beca use the wires will be in the way.

Wire Size and Terminal Screw Torque

Each termi nal accepts up to two wires with th e f ollowin g restrictions:
