Chapter 1 Controllers and I/O Modules
These are the available ControlLogix Digital DC Input Modules.
Replacing 6ES5 420-4UA13/14 and 6ES5 430-4UA13/14 DI Modules
The simplest replacement for these modules would be to replace them with
ControlLogix 1756-IB32 DI module.
If there are more than 16 spare inputs on the DI modules, it may be better to
replace them with the ControlLogix 1756-IB16 module.
It is often the case that the density of wiring on a 32-channel module makes
wiring and troubleshooting difficult. If this is the case, consider replacing these
modules with two 16-channel ControlLogix 1756-IB16 modules.
If additional diagnostic features are required, then the 1756-IB32D module
can be used. This module can detect an open wire condition for each I/O
point in the field and set an associated diagnostic bit that can be monitored in
the project.
The 1756-IB32I module would be a possible replacement if some/all inputs
must be individually isolated.
