About the ICS TRIPLEX T8431C Analog Input Module

The TrustedTM TMR 24V dc Analogue Input module interfaces to 40 sourcing field input devices, acting
as a current sink for all these devices. Comprehensive diagnostic tests are performed on each input
channel. Fault tolerance is achieved through a Triple Modular Redundant (TMR) architecture within the
module for each of the 40 input channels.
Using the built-in line-monitoring feature, the module can detect open and shorted field cables. Line
monitoring functions are independently configured for each input channel.
The module provides on-board Sequence of Events (SOE) reporting with a resolution of 1ms. A
change of state triggers an SOE entry. States are determined by voltage thresholds that can be
configured on a per channel basis. When the field voltage and field return are connected to the
auxiliary input channels of the module, thresholds can be specified as a ratio of the field supply voltage. 

Features
• 40 Triple Modular Redundant (TMR) input channels per module.
• Comprehensive, diagnostics and self-test.
• Selectable line monitoring per channel to detect open circuit and short circuit field wiring
faults.
• 2500Vdc opto/galvanic isolation barrier.
• On-board Sequence of Events (SOE) reporting with 1ms resolution.
• Module can be hot-replaced on-line using dedicated Companion (adjacent) Slot or
SmartSlot (one spare slot for many modules) configurations.
• Front panel input status LEDs for each channel indicate input status and field wiring
faults.
• Front panel module status LEDs indicate module health and operational mode (Active,
Standby, Educated)
• T:V Certified IEC 61508 SIL 3
