ICS Triplex T9802 Digital Input Module | AADvance SIL3 Safety

Product Description

Overview

The ICS Triplex T9802 is a high-performance, dual-channel digital input module engineered for safety-critical environments. As part of the AADvance™ family, it provides reliable fault-tolerant performance for Safety Instrumented Systems (SIS) requiring SIL 3 compliance according to IEC 61508. The module is ideal for Emergency Shutdown (ESD), burner management, turbine control, and other high-integrity applications.

Module Description

The T9802 integrates seamlessly into the Trusted™ TMR platform, leveraging Triple Modular Redundant (TMR) technology to ensure continuous operation even under hardware faults. Its robust design enables hot-swapping, allowing maintenance or module replacement without interrupting system operation.

• Redundant Architecture: Dual-channel input with 2-out-of-3 (2oo3) voting logic ensures fault tolerance and high availability.

• Safety Certification: SIL 3 certified for critical safety loops.

• Isolation: High-voltage separation between channels and power supply protects the module and connected devices.

• Installation: DIN rail mountable for efficient cabinet integration.

Performance Characteristics

Key Technical Features

2oo3 Voting Logic
Each input signal is processed across three independent circuits, ensuring that a single hardware fault does not disrupt module operation.

Advanced Line Monitoring
Detects field-side anomalies including open circuits, short circuits, and insulation breakdown.

High-Resolution SOE Logging
Integrated Sequence of Events (SOE) allows timestamped tracking of output changes for detailed incident analysis.

Active/Standby Support
Pairs with companion modules for seamless online testing, maintenance, and redundancy without interrupting process outputs.

Applications

• Emergency Shutdown (ESD) systems

• Burner Management Systems (BMS)

• Turbine and compressor safety control

• Nuclear power plant monitoring

• Chemical and oil & gas process protection
