Using 1715 Analog I/O Module Features
1715 Analog Module
Overview
The 1715 analog I/O modules mount in a 1715 Redundant I/O System and use
an I/O termination assembly mounted in an I/O base unit to communicate via
redundant 1715 adapter modules.
Before you install and use your module, you must do the following:
• Install and ground a user-supplied, 24V DC power supply.
• Determine whether you are using your analog I/O module in Simplex or
Duplex mode.
• Install the correct termination assembly based on your determination for
either simplex or duplex operation.
Each analog I/O module is an isolated module that plugs into a single position of
the I/O base unit and a termination assembly that is mounted to the base unit.
Analog I/O modules can be configured in the Logix Designer application as
simplex or duplex and then by selecting one of the two available termination
assemblies, the Logix Designer application, and the required number of modules.
Termination assemblies provide termination for the field I/O channels and, by
the use of coding pegs and sockets, are matched to a specific analog I/O module.
Module keying can also be set in the RSLogix 5000 or Logix Designer project.
Field connections are made at the terminal block connectors on the termination
assembly.
