Analog Input Modules
60 Hz Rejection and Fast Response
(T3420A and T3420AF)
Issue 1, March, 06
Analog input modules provide data input for a maximum of
16 field analog signals per module. Two types of modules are
available: one for high noise immunity (60 Hz rejection) and
one with low noise immunity (fast response).
Features
· Sixteen single-ended or eight differential voltage inputs.
Interface to current inputs using external 250 ohm resistors for
current to voltage conversion (resistors are provided as part of
the analog input termination blocks, catalog number T3325-
XX).
· Fault tolerant operation when connected in parallel with
redundant modules of the same type.
· Hot replaceable.
· Jumper-selectable input ranges.
· 12-bit analog to digital resolution (1 part in 4096).
· Sample rate of all channels in 1.8 msec (differential) or 3.6
msec (single-ended).
· 60 Hz rejection (T3420A) and fast response (T3420AF)
versions available.
· 2500 volt isolation between analog and digital logic circuits.
· Individual front panel indicators on each module show module
active and fault status.
· TÜV certified for safety, Risk Class 5.
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
