AC Digital Input Module
110 VAC
(T7404)
Issue 1, March, 06
The AC digital input module provides input sensing for 16 
field input switches. One type of module is available for 
interfacing to inputs powered from 110 VAC field power 
supplies. The module's triplicated I/O Safetybus interface 
ensures that no failure in the module can affect the operation 
of the Regent system or other I/O modules in the system. 
Extensive fault detection and annunciation of critical 
redundant circuits help prevent the controllers from receiving 
erroneous data from a faulty input module. 
Features
·
Sixteen input circuits, configured as two isolated groups of
eight circuits each.
·
Fault tolerant operation when connected in parallel with
redundant modules of the same type.
·
Hot-replaceable.
·
Automatic self-testing of triplicated I/O Safetybus circuits and
many simplex logic circuits.
·
Individual front panel indicators on each module show active
and fault status and logic-side input on/off status.
·
2500 volt minimum electrical isolation between field and logic
circuits.
·
TÜV certified, Risk Class 5.
Three AC digital input modules can be connected in parallel 
to obtain fault tolerant input sensing. In this triple module 
configuration, a failed module can be removed and replaced 
without interrupting the input signals.
