Chapter 2 Quick Start for Experienced Users

The module’s maximum current draw is:

• 100 mA for 5V DC.

• 40 mA for 24V DC.

1. Check that the bus lever of the module to be installed is in the unlocked

(fully right) position.

2. Use the upper and lower tongue-and-groove slots (1) to secure the

modules together (or to a controller).

3. Move the module back along the tongue-and-groove slots until the bus

connectors (2) line up with each other.

4. Push the bus lever back slightly to clear the positioning tab (3) by using

your fingers or a small screwdriver.

5. Move the bus lever fully to the left (4) until it clicks to allow

communication between the controller and module.

assembled before or after mounting.

ATTENTION: Remove power before removing or inserting this module. If

you remove or insert a module with power applied, an electrical arc may

occur.

IMPORTANT

To reduce the effects of electrical noise, install the 1769-IT6 module at

least two slots away from Compact I/O 120/240V AC power supplies.
