Installing the Linear Positioning Module

This chapter tells you how to install the module in the I/O chassis and how to

configure the module’s analog outputs by setting DIP switches. Before you

install the module:

make sure your power supply is adequate

plan your module’s location in the I/O chassis

take steps to avoid electrostatic discharge

Avoiding Backplane Power Supply Overload

Make sure your power supply can handle the extra load before installing the

module in your I/O chassis. Add the module’s current requirement, listed on the

module’s label, to the currents required by other modules inserted in the I/O

chassis. If the backplane power supply rating is less than the total current

required, you’ll need a larger power supply.

Here are the current ratings for the various Allen-Bradley power supply

modules.

This Power Supply Module:

Is Rated at:

1771P1

6.5A

1771P2

6.5A

1771P4 8A

1771P5

1771P7

16A

Planning Module Location

The module requires one I/O chassis slot. You can install it in any slot in the I/O

chassis. The module uses both the output image table byte and the input image

table byte that corresponds to its location address.
