PRODUCT DESCRIPTION

 ControlLogix digital I/O modules are input and output modules that provide On/Off detection and actuation. By using the Producer/Consumer network model, digital I/O 
modules can produce information when needed while providing additional system functions. 


Description:

Installation Requirements

Before you install the module, you must complete these steps.

1. Install a 1756 ControlLogix chassis.

2. Install a 1756 ControlLogix power supply.

Install the Module

You can install or remove a module while chassis power is applied.

Slide the module into the slot in the chassis until the locking tabs click.

Key the Removable Terminal Block

Key the RTB to help prevent inadvertently connecting the incorrect RTB to your 

module.

1. Push the U-shaped band onto the module until the band snaps into place.

2. Insert wedge-shaped tabs into positions on the RTB that correspond to 

unkeyed module positions on the module until they stop.

Connect Wiring

You can use an RTB or a Bulletin 1492 prewired interface module (IFM) to connect 

wires to your module. 

If you’re using an RTB, see Recommendations for Wiring Your RTB, to connect wires 

to the RTB. IFMs are prewired before shipping.

Wire a Cage Clamp-style RTB

3. Insert the wire into the terminal.

4. Turn the screw clockwise to close the terminal on the wire. 

Wire a Spring Clamp

1. Insert the screwdriver into the outer hole of the RTB.

2. Insert the wire into the open terminal and remove the screwdriver.

Recommendations for Wiring Your RTB

We recommend that you follow these guidelines when wiring your RTB:

• Begin wiring the RTB at the bottom terminals and move up.

• Use a tie to secure the wires in the strain relief (bottom) area of the RTB.

• Order and use an extended-depth housing (catalog number 1756-TBE) for 

applications that require heavy gauge wiring.

ATTENTION: The module is designed to support removal and 

insertion under power (RIUP). However, when you remove or 

insert a removable terminal block (RTB) with field-side power 

applied, unintended machine motion or loss of process control 

can occur. Exercise extreme caution when using this feature. 

We recommend that you remove field-side power before 

installing the RTB onto the module.

SHOCK HAZARD: If the RTB is installed onto the module while 

the field-side power is applied, the RTB is electrically live. Do 

not touch the RTB terminals. Failure to observe this caution 

can result in personal injury.

WARNING: If you connect or disconnect wiring while the field-side 

power is on, an electric arc can occur. This could cause an 

explosion in hazardous location installations. Be sure that power 

is removed or the area is nonhazardous before proceeding.

ATTENTION: If multiple power sources are used, do not exceed 

the specified isolation voltage. 

ATTENTION: When using the 1756-TBNH, do not wire more than 

two 0.33...2.1 mm2 (22...14 AWG) conductors on any single 

terminal. Use only the same size wires with no intermixing of 

solid and stranded wire types.

When using the 1756-TBSH, do not wire more than one 

conductor on any single terminal.

ATTENTION: The ControlLogix system has been agency 

certified using only the ControlLogix RTBs (1756-TBNH and 

1756-TBSH). Any application that requires agency certification 

of the ControlLogix system using other wiring termination 

methods may require application-specific approval by the 

certifying agency
