The T8461CX is a 40‑channel Triple Modular Redundant (TMR) digital output module from ICS Triplex‘s Trusted series, engineered for safety‑critical applications within the Trusted Safety Instrumented System (SIS). The T8461CX provides fault‑tolerant output control for up to 40 field devices, with 2‑out‑of‑3 (2oo3) voting per channel ensuring correct operation even during a single fault. The T8461CX features comprehensive diagnostics including automatic line monitoring (open/short circuit detection), stuck‑on/stuck‑off testing, and onboard Sequence of Events (SOE) reporting with 1 ms resolution. With SIL 3 certification and hot‑swap capability, the T8461CX delivers reliable, high‑integrity digital output control for emergency shutdown (ESD), fire & gas (F&G), and other critical protection systems.
True TMR Architecture with 2oo3 Voting – Each of the 40 output channels is implemented with three independent processing paths and 2‑out‑of‑3 (2oo3) voting. This eliminates single points of failure—a fault in any one channel cannot produce an incorrect output, ensuring SIL 3 integrity for safety‑critical applications.
Comprehensive Diagnostic Coverage (≥99%) – Triplicated diagnostic tests continuously monitor current, voltage, and output state on each voted channel, detecting stuck‑on, stuck‑off, open circuit, and short circuit failures. This high diagnostic coverage significantly reduces the probability of dangerous undetected failures.
Hot‑Swap Capability – Supports online replacement using Companion Slot or SmartSlot configurations, allowing module replacement without system shutdown or process interruption.
High Density with Isolated Power Groups – 40 channels in a single slot with 5 isolated power groups (8 channels per group), maximizing cabinet space efficiency while maintaining safe power distribution.
SIL 3 Certified – TÜV certified per IEC 61508 SIL 3, meeting the highest safety integrity level for industrial safety systems.
Automatic Overcurrent Protection – Per‑channel electronic overcurrent protection eliminates the need for external fuses, reducing maintenance and improving reliability.
40 TMR Digital Output Channels – Triple Modular Redundant architecture with 2oo3 voting per channel
Dual Voltage Operation – Configurable for 24 VDC or 48 VDC field devices
Comprehensive Diagnostics – Automatic self‑tests including current/voltage measurements, stuck‑on/stuck‑off detection, and open/short circuit line monitoring
Onboard SOE Reporting – Sequence of Events recording with 1 ms resolution and ±10 ms timestamp accuracy
Hot‑Swap Capability – Online replacement without system shutdown using Companion Slot or SmartSlot
Isolated Power Groups – 5 independent power groups (8 channels per group) for enhanced safety and fault isolation
Front Panel LEDs – Per‑channel output status, field wiring faults, and module health indicators
2500 V Impulse Withstand Isolation – Opto/galvanic isolation barrier for electrical protection
Automatic Overcurrent Protection – Per‑channel electronic protection, no external fuses required
Fail‑Safe Design – De‑energized on power loss or fault (safe state)
The T8461CX operates as a high‑integrity digital output interface within the Trusted TMR safety architecture. Each of the 40 output channels is implemented with three independent processing paths, providing hardware‑level Triple Modular Redundancy (TMR). The module continuously executes a 2‑out‑of‑3 (2oo3) voting mechanism: the three paths independently evaluate each output command; the final output is only driven when at least two paths agree. This architecture eliminates single points of failure—a fault in any one path cannot produce an incorrect output, and the module is guaranteed to operate correctly with a single fault present.
The module performs triplicated diagnostic tests on each voted output channel, including measurements for current and voltage. Tests are also executed for stuck‑on and stuck‑off failures. Automatic line monitoring detects both open circuit and short circuit failures in field wiring and load devices. Upon detection of a fault, the module can isolate the affected channel while other channels continue to operate normally.
Each of the 40 outputs is organized into 5 isolated power groups of 8 channels each. This isolation ensures that a fault in one power group does not affect others. The module provides onboard Sequence of Events (SOE) reporting with 1 ms resolution; an output change of state triggers an SOE entry, timestamped with ±10 ms accuracy. The module is hot‑swappable, supporting online replacement without system shutdown. Outputs are automatically de‑energized (fail‑safe) upon loss of power or detection of a module fault.
