Replacing 6ES5 431-4UA12 DI Modules
This module requires voltages from 24…60V to register an input as ON. The
actual values of input voltage presented by the input signals should be
reviewed and if they are all found to be within the range of 30…60V then this
module can be replaced by the 1756-IC16 module, while any 24V inputs could
be connected to a 1756-IB16 module.
Replacing 6ES5 432-4UA12 DI Modules
The 432 digital input module accepts 32 process signals and emits a process
alarm if the logic state at one of its inputs changes.
This module could be replaced with a ControlLogix 1756-IB32 DI module
where the process alarm could be generated by configuring a Module Input
Data State Change as a Trigger for an Event Task. See “Event Task” on
page 34
for more information.
Replacing 6ES5 434-4UA12 DI Modules
This module requires voltages from 5V…15V to register an input as ON. The
actual values of input voltage presented by the input signals should be
reviewed to determine which of the following ControlLogix modules would be
the best replacement.
• 1756-IG16 (5V TTL source)
• 1756-IV16/1756-IV32 (12/24 DC source)
The following table lists the available Siemens S5 Digital AC Input Modules.
