ControlLogix® controllers use analog I/O modules to control devices in a
ControlLogix control system. The modules are installed in a ControlLogix
chassis and use a removable terminal block (RTB) or a Bulletin 1492 interface
(1)
module
cable to connect to field-side wiring.
The modules use the Producer/Consumer network communication model. This
communication is an intelligent data exchange between modules and other
system devices in which each module produces data without first being polled.
Before you install and use your module, complete the following tasks:
• Install and ground a 1756 ControlLogix chassis and power supply
You can use a standard power supply or a redundant power supply.
For more information on how to install the 1756 ControlLogix chassis
and power supplies, see
• Verify that you have an RTB or IFM and its components.
IMPORTANT
(1) The ControlLogix system has been agency certified using only the ControlLogix RTBs (catalog numbers 1756-TBCH, 1756-TBNH,
1756-TBSH and 1756-TBS6H). Any application that requires agency certification of the ControlLogix system using other wiring
termination methods can require application specific approval by the certifying agency.
(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
distributor or Rockwell Automation representative.
