Description
The ICS Triplex T9432 is a high-integrity Digital Input Module designed for the Trusted™ Triple Modular Redundancy (TMR) system. This module provides 32 isolated input channels, specifically engineered for safety-critical applications where maximum availability and fault tolerance are required. By utilizing a TMR architecture, the T9432 performs internal 2-out-of-3 voting to ensure that a single component failure does not compromise the safety function or lead to a nuisance trip.

Application Fields
The ICS Triplex T9432 is a cornerstone of “Active-Two-Out-Of-Three” safety systems in high-risk industries:
- Emergency Shutdown (ESD): Monitoring critical push-buttons and process switches in chemical plants.
- Fire & Gas (F&G) Systems: Integrating flame, smoke, and gas detectors into the safety logic.
- Burner Management Systems (BMS): Overseeing safety interlocks for large industrial boilers and furnaces.
- Turbine Control: Managing trip signals and status monitoring for large steam and gas turbines.
- Subsea Control: High-reliability monitoring of subsea production systems where maintenance is difficult.

Product Operation Instructions
- Chassis Installation: Slide the T9432 module into an available slot in the Trusted Controller Chassis. The module is designed for “Hot Replacement,” allowing it to be inserted while the rest of the system is operational.
- Field Termination: Connect field wiring via the appropriate Trusted Field Termination Assembly (FTA). This ensures that the triple-redundant signals are correctly routed from the field to the module’s internal processing units.
- Redundancy Link: The module automatically synchronizes with the Trusted Controller via the TMR Inter-Module Bus. No manual synchronization is required upon insertion.
- Diagnostics: Monitor the front-panel status LEDs. The “Healthy” LED indicates overall module status, while individual channel LEDs provide visual confirmation of the input state and detected line faults.
- Line Monitoring: Configure the module to detect open circuits or short circuits in the field wiring by using end-of-line (EOL) resistors, enhancing the diagnostic coverage of the safety loop.
Q&A: Common Questions
Q: What makes the T9432 different from a standard PLC input module? A: A standard module is “Simplex,” meaning one failure can cause a shutdown. The T9432 has three internal “slices” that vote on every input. It can lose one internal slice and continue to operate correctly without interrupting the process.
Q: Does this module support SOE (Sequence of Events)? A: Yes, the T9432 provides high-resolution time-stamping for all input changes, allowing for detailed millisecond-accurate analysis of system trips.
Q: Can I use this module with 120V AC signals? A: No, the T9432 is specifically rated for 24V DC. For AC signals, a different module variant or interposing relays must be used to match the voltage requirements.
