Product Description

The ICS Triplex T8402 is a high-density digital input interface module designed for fault-tolerant operation within the Trusted Safety Instrumented System (SIS) and critical process control platforms. The device interfaces with up to 60 field input devices, utilizing a One-Out-Of-Two D (1oo2D) voting architecture across all channels to provide comprehensive fault detection and tolerance. Each input line is duplicated and measured via sigma-delta ($\Sigma\Delta$) input circuits, enabling precise voltage conversion and real-time comparison against user-configurable threshold levels for contact state determination and open or short circuit line monitoring.

Features

60 duplicated input channels per module providing 1oo2D voting architecture.
Individual sigma-delta ($\Sigma\Delta$) analog-to-digital converters for each channel on every slice.
Selectable line monitoring per channel for open-circuit and short-circuit field wiring fault detection.
Integrated Sequence of Events (SOE) reporting with 1 ms event resolution and $\pm$10 ms time-stamp accuracy.
Configurable 50/60 Hz digital filtering to reduce field-induced electrical noise.
Hot-swappable online replacement via dedicated Companion Slot or SmartSlot configurations.
Front panel tri-color LED indicators for slice health, operational mode, and module status voting.
2500 V impulse withstand isolation barrier for field protection.

Applications

Emergency Shutdown Systems (ESD)
Fire and Gas Detection Systems (F&G)
Burner Management Systems (BMS)
Turbomachinery Control and Safety
High-Integrity Pressure Protection Systems (HIPPS)
Critical Industrial Process Automation and Safety Instrumented Functions (SIF)

Installation Guidelines

Visual Inspection: Inspect the unit housing and rear connector pins for mechanical damage prior to chassis insertion. Do not attempt to straighten bent pins.
Module Keying: Ensure polarising keying pins are configured according to system specifications. For model T8402, remove keying pins 1, 3, and 4 on the cable hood.
Insertion Procedure: Release ejector tabs using the release key, align the unit with the chassis slot guides, and slide in smoothly until seated. Close top and bottom ejector levers until fully locked.
Hot Swapping: Online replacement is supported using a dedicated Companion Slot or SmartSlot configuration. Verify SmartSlot interconnect wiring before performing standby swap operations.
Electrostatic Precaution: Static handling procedures must be maintained. Do not touch exposed pin connections or attempt disassembly of the module enclosure.
