DC Digital Input Modules
24 VDC, 48 VDC and 120 VDC
(T3401, T3402 and T3408)
Issue 1, March, 06
DC digital input modules provide input sensing for 16 field
input switches. Three types of modules are available for
interfacing to inputs powered from 24, 48, or 120 VDC field
power supplies. Each 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 DC 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.
