Module Installation

Compact I/O is suitable for use in an industrial environment when installed in accordance with these instructions. Specifically, this equipment is intended for use in clean, dry

environments (Pollution degree 2

(2)

(IEC 60664-1).

(3)

Prevent Electrostatic Discharge

(1)

) and to circuits not exceeding Over Voltage Category

ATTENTION

Remove Power

ATTENTION

Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins. Follow these guidelines when you handle the module:

– Touch a grounded object to discharge static potential. – Wear an approved wrist-strap grounding device. – Do not touch the bus connector or connector pins. – Do not touch circuit components inside the module. – If available, use a static-safe work station. – When not in use, keep the module in its static-shield box.

Remove power before removing or inserting this module. When you remove or insert a module 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

unintended machine motion

– causing an explosion in a hazardous environment Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance.

(1)

Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a temporary conductivity caused by condensation shall be expected.

(2)

Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are controlled and do not exceed the impulse voltage capability of the product’s insulation.

(3)

Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.

Compact 32-point 24V dc Sink/Source Input Module 5

System Assembly

The module can be attached to the controller or an adjacent I/O module before or after mounting. For mounting instructions, see Panel Mounting on page 6, or DIN Rail Mounting on page 8. To work with a system that is already mounted, see Replacing a Single Module within a System on page 8.

The following procedure shows you how to assemble the Compact I/O system.

30536-M

1. Disconnect power.

2. Check that the bus lever of the module to be installed is in the unlocked (fully right)

position.

3. Use the upper and lower tongue-and-groove slots (1) to secure the modules together (or to a controller).

4. Move the module back along the tongue-and-groove slots until the bus connectors (2) line up with each other.

5. Push the bus lever back slightly to clear the positioning tab (3). Use your fingers or a small screw driver.

6. To allow communication between the controller and module, move the bus lever fully to the left (4) until it clicks. Ensure it is locked firmly in place.

ATTENTION

When attaching I/O modules, it is very important that the bus connectors are securely locked together to ensure proper electrical connection.

7. Attach an end cap terminator (5) to the last module in the system by using the tongue-and-groove slots as before.

8. Lock the end cap bus terminator (6).

IMPORTANT

A 1769-ECR or 1769-ECL right or left end cap must be used to terminate the end of the serial communication bus.

Mounting Expansion I/O

ATTENTION

Minimum Spacing

Maintain spacing from enclosure walls, wireways, adjacent equipment, etc. Allow 50 mm (2 in.) of space on all sides for adequate ventilation, as shown:

Panel Mounting

Mount the module to a panel using two screws per module. Use M4 or #8 panhead screws. Mounting screws are required on every module.

During panel or DIN rail mounting of all devices, 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 on power up.
