Details
The Trusted® TMR 24 Vdc Analog 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 onboard Sequence of Events (SOE) reporting with a resolution of 1 ms. 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, automatic diagnostics and self-test. • Selectable line monitoring per channel to detect open circuit and short circuit field wiring faults. • 2500V impulse withstand opto/galvanic isolation barrier. • Onboard Sequence of Events (SOE) reporting with 1 ms resolution. • Module can be hot-replaced online using dedicated Companion (adjacent) Slot or SmartSlot (one spare slot for many modules) configurations. • Front panel input status Light Emitting Diodes (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). • TϋV Certified IEC 61508 SIL 3.
The Trusted® TMR 24 Vdc Analog Input Module is a member of the Trusted range of Input/Output (I/O) modules. All Trusted I/O Modules share common functionality and form. At the most general level, all I/O Modules interface to the Inter-Module Bus (IMB) which provides power and allows communication with the Trusted TMR Processor. In addition, all Modules have a field interface that is used to connect to module-specific signals in the field. All Modules are Triple Modular Redundant (TMR).
All High Integrity I/O Modules comprise four sections: Host Interface Unit (HIU), the Field Interface Unit (FIU), the Field Termination Unit (FTU) and the Front Panel Unit (or FPU). Figure 2 shows a simplified functional block diagram of the Trusted 24 Vdc Analog Input Module.
