64-Point Digital Input
Modules
Each 64-point Digital Input (DI)
module has three isolated channels
which independently process all data
input to the module. A microprocessor
on each channel scans each input point,
compiles data and transmits it to the
Main Processors on demand. Then
input data is voted at the Main Proces
sors just prior to processing to ensure
the highest integrity.
All Digital Input Modules sustain
complete, ongoing diagnostics for each
channel. A failure on any channel acti
vates the Fault indicator which in turn
activates the chassis alarm. A TMR
module is guaranteed to operate prop
erly in the presence of a single fault and
may operate properly with certain kinds
of multiple faults.
All Digital Input Modules support hot
spare modules and require a separate
external termination panel (ETP) with a
cable interface to the Tricon backplane.
Each module is mechanically keyed to
prevent improper installation in a
chassis.
