Check the contents of shipping box.

Reference

Unpack the shipping box making sure that the contents include:

• analog input module (Catalog Number 1746NI8)

• removable terminal block (factoryinstalled)

If the contents are incomplete, call your local AllenBradley representative for assistance.

Ensure that your chassis and power supply support the 1746NI8

module.

Reference

Review the power requirements of your system to see that your chassis supports the module:

• If combining a 1746NI8 module with another I/O module in a fixed controller, refer to the I/O

module compatibility table found in chapter 3.

• For modular style systems, calculate the total load on the system power supply using the

procedure described in the SLC Installation & Operation Manual for Modular Style Controllers

(publication 17476.2) or the SLC 500 Family System Overview (publication 17472.30).

• The 1746NI8 backplane current consumption is 200 mA at 5V dc and 100 mA at 24V dc.
