      Information

      Overview Manuals Common Applications Product Precautions
      ICS Triplex T8403 is a Trusted TMR 24 Vdc digital input module with 40 triplicated input channels. It measures each field input against configurable thresholds and provides line monitoring, diagnostics and 1 ms Sequence of Events reporting.
      • Forty triplicated 24 Vdc input channels
      • Per-channel open- and short-circuit line monitoring
      • One-millisecond Sequence of Events reporting
      • Online replacement through Companion Slot or SmartSlot

      Record the T8403 module revision, chassis slot, field-cable assembly, threshold configuration and line-monitoring settings before replacement. Verify all 40 channel states, field wiring diagnostics and Active/Standby status before returning the Trusted system to service.

      Important Notice: Verify T8403 from the physical marking and current manufacturer documentation before installation or configuration.

      Important Notice: Use these model-specific records together with the current manufacturer publication and the installed-system documentation.

      Emergency shutdown inputs
      Acquires safety-related 24 Vdc field contacts with TMR processing and diagnostics.
      Fire and gas input monitoring
      Uses configurable thresholds and optional line monitoring for supervised field circuits.
      Sequence-of-events capture
      Records configured input state changes with 1 ms resolution.
      Online module maintenance
      Supports controlled Active/Standby transfer using Companion Slot or SmartSlot arrangements.
      Read the applicable ICS Triplex instructions before work. Verify T8403 and the installed system configuration.
      1
      Verify the exact T8403 catalog number, revision and intended Trusted chassis slot.
      2
      Record the module type, revision and serial number before installation.
      3
      Inspect the housing and rear connector; do not install a module with damage or bent pins.
      4
      Use static-handling controls and never touch exposed connector pins.
      5
      Confirm the correct field-cable assembly and FTA/VFTA before insertion.
      6
      Do not force the module if it does not enter the slot with minimum resistance.
      7
      Restore threshold and line-monitoring configuration for every used channel.
      8
      Verify all channel LEDs, module status, SOE operation and field-wiring diagnostics before release.

      FAQS

      • How many inputs does ICS Triplex T8403 provide?
        T8403 provides 40 field input channels.
      • Why is each ICS Triplex T8403 channel described as TMR?
        Each field input is triplicated and processed by three isolated slices so a single slice fault does not determine the reported state.
      • Can ICS Triplex T8403 detect field wiring faults?
        Yes. Selectable per-channel line monitoring can detect open-circuit and short-circuit field cable conditions when the approved line-monitoring components are installed.
      • What Sequence of Events resolution does ICS Triplex T8403 provide?
        The module provides onboard SOE reporting with 1 ms resolution.
      • Can ICS Triplex T8403 be replaced online?
        Yes. The manual supports online replacement with a dedicated Companion Slot or a SmartSlot configuration under the approved procedure.
      • What isolation is documented for ICS Triplex T8403?
        The product description specifies a 2500 V impulse-withstand opto/galvanic isolation barrier.
      • What should be inspected before inserting ICS Triplex T8403?
        Inspect the housing and rear I/O connector for damage or bent pins, confirm the correct module type and field-cable assembly, and use ESD precautions.
      • What proves successful commissioning of ICS Triplex T8403?
        All configured channel states, thresholds, line-monitoring indications, SOE entries and Active/Standby module status must agree with the approved test record.
