What Are ControlLogix Analog I/O Modules? Chapter 1
I/O Module in the
ControlLogix System
ControlLogix modules mount in a ControlLogix chassis and use a removable
terminal block (RTB) or a Bulletin 1492 interface module
(1)
cable to connect
to all field-side wiring.
Before you install and use your module, you should do the following:
• Install and ground a 1756 chassis and power supply
(2)
. To install these
products, refer to the publications listed in Additional Resources
on page 13.
• Order and receive an RTB or IFM and its components for your
application.
(1)
The ControlLogix system has been agency certified using only the ControlLogix RTBs (1756-TBCH, 1756-TBNH,
1756-TBSH and 1756-TBS6H). Any application that requires agency certification of the ControlLogix system
using other wiring termination methods may require application specific approval by the certifying agency. To
see what analog interface modules are used with each ControlLogix analog I/O module, see Appendix F
.
(2)
In addition to standard ControlLogix power supplies, ControlLogix Redundant Power Supplies are also available
for your application. For more information on these supplies, see the ControlLogix Selection Guide,
publication 1756-SG001
, or contact your local Rockwell Automation distributor or sales representative.
IMPORTANT
RTBs and IFMs are not included with your
module purchase.
