Dual Analogue Input Module-T8432
FRONT PANEL
DESCRIPTION
The Trusted
module interfaces to 60 single-ended
field input devices. A wide input
voltage range and programmable
thresholds allow the module to be
used in current source and current
sink configurations. Comprehensive
diagnostic tests are performed on
each input channel, including tests for
stuck on and stuck off failures. Fault
tolerance is achieved through Dual
Redundancy within the same module
for each of the 60 input channels.
TM
Dual Analogue Input
The module can apply a digital filter to
each input channel. Individual
channels can be configured for high
noise immunity (50Hz or 60Hz
rejection), low noise immunity (fast
response), or pass-through operation
(no filtering).
Each input channel has four
configurable state thresholds which
may be assigned to SOE reporting. A
change of state triggers an SOE
entry. The on-board Sequence of
Events (SOE) reporting has a
resolution of 1ms.
Each dual section of the module,
referred to as a slice, conditions and
measures each channel
independently. Each slice is optoisolated up to 2500V dc. Each slice
sends its data to a safety layer
hardware voter that presents the
information from both slices to the
Trusted
fault is detected on a slice of the
module, the Trusted
Processor will flag the error,
indicating the need to replace the
module. The Trusted
Processor will continue to use the
information provided by the remaining
slice until a replacement module is
available. Replacement modules can
be located in a standby slot next to
the module or in a designated
SmartSlot with a temporary
connection to the same Trusted
Termination Assembly.
module slot in a Trusted
Chassis or Expander chassis. Once
the I/O module configuration is set,
mechanical keying is available on all
I/O modules to prevent inserting a
module into an incorrect slot.
