ROCKWELL AUTOMATION ICS Triplex T8403 Trusted TMR 24 Vdc 40 Channel Digital Input Module

PRODUCT: T8403 Trusted TMR 24 Vdc Digital Input Module 40 Channel ICS Rockwell

PD-T8403

Product Overview

The Trusted® TMR 24 Vdc Digital Input module 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 resulting field voltage measurement is compared to user configurable threshold voltages to
determine the reported field input state. When a line-monitoring device is installed at the field
switch, the module can detect open and short circuit field cables. Line monitoring functions are
independently configured for each input channel. The triplicated voltage measurement, coupled
with on-board diagnostic testing, provides 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 are determined by voltage thresholds that can be
configured on a per channel basis.

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
• 2500 V impulse withstand opto/galvanic isolation barrier.
• On-board Sequence of Events (SOE) reporting with 1 ms resolution.
• Configurable 50/60 Hz digital filtering to eliminate field induced noise.
• 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).
• TϋV Certified IEC 61508 SIL 3.
