Trusted TMR 120 Vac Digital Input Module 40
Channel
Product Overview
The Trusted® TMR 120 Vac Digital Input interfaces to 40 field input devices. Fault tolerance is
achieved through a Triple Modular Redundant (TMR) architecture within the Module for each of
the 40 input channels.
Each field input is triplicated and the input voltage is measured using a sigma-delta input circuit.
The field voltage signal is digitally processed to compute the alternating current (ac) amplitude,
which is compared to fixed threshold voltages to determine the reported field input state. The
triplicated voltage measurements, coupled with on-board diagnostic testing, provide
comprehensive fault detection and tolerance.
The Module provides on-board Sequence of Events (SOE) reporting with a resolution of 1 ms. A
change of state triggers an SOE entry. States for each channel are determined by comparing the
input signal amplitude with fixed voltage thresholds on a per channel basis.
Features:
• 40 Triple Modular Redundant (TMR) input channels per Module.
• Comprehensive, automatic diagnostics and self-test.
• 2500 V impulse withstand opto/galvanic isolation barrier.
• On-board Sequence of Events (SOE) reporting with 1 ms 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 Light Emitting Diodes (LEDs) for each channel indicate input status
and open inputs.
• Front Panel Module status LEDs indicate Module health and operational mode (Active,
Standby, Educated).

    1. Description 1. Description The Trusted TMR 120 Vac Digital Input 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.

  • Page 12: Field Termination Unit (Ftu)

    I/O signals. Each Module has three FIUs, one per slice. For the Trusted TMR 120 Vac Digital Input, each FIU contains an individual analogue to digital converter (ADC) for each of the 40 field inputs.

  • Page 13: Host Interface Unit (Hiu)

    Trusted TMR 120 Vac Digital Input Module 40 Channel 1. Description The FIU also measures a range of on-board “housekeeping” signals that assist in monitoring the performance and operating conditions of the Module. These signals include power supply voltages, current consumption, on-board reference voltages, and board temperature.
