1-4 What is the ControlLogix Sequence of Events Module?
Understanding the
Module’s Physical Features ControlLogix modules mount in a ControlLogix chassis and use a
Removable Terminal Block (RTB), or a Bulletin 1492 Interface Module
cable that connects to an IFM, to connect all field-side wiring. Before
you use your module, you should have already:
• installed and grounded a 1756 chassis and power supply. To
install these products, refer to the publications listed in
Table Preface.3 on page Preface-2.
• ordered and received an RTB or IFM and its components for
your application; neither RTBs nor IFMs are included with your
module purchase.

Table 1.3 Physical Features on the ControlLogix Sequence of Events Module
Physical Feature: Description:
Backplane connector The backplane connector interface for the ControlLogix system connects the module to the ControlLogix
backplane.
Connector pins Input/output, power and grounding connections are made to the module through these pins with the use of
an RTB or IFM.
Locking tab The locking tab anchors the RTB or IFM cable on the module, maintaining wiring connections.
Slots for keying Mechanically keys the RTB to prevent inadvertently making the wrong wire connections to your module.
Status indicators Indicators display the status of communication, module health and input/output devices. Use these
indicators to help in troubleshooting.
Top and bottom guides Guides provide assistance in seating the RTB or IFM cable onto the module.
Jumper bar Device you can use to connect multiple points in non-isolated wiring application, as shown on page 3-6.
