The ICS TRIPLEX T8403C is a Trusted TMR 24 Vdc digital input module engineered for safety-critical applications requiring the highest levels of integrity. Part of the Trusted 8000 Series, the T8403C provides 40 discrete input channels, each backed by full Triple Modular Redundancy (TMR). Every field signal is processed by three independent circuits and voted via a 2oo3 mechanism, eliminating single points of failure. The ICS TRIPLEX T8403C also offers advanced online diagnostics, 1 ms SOE recording, and hot-swap capability, making it ideal for demanding SIL 3 safety systems.
Emergency Shutdown (ESD) Systems – high‑integrity monitoring of emergency stop buttons, pressure switches, and isolation valves
Fire & Gas (F&G) Protection – reliable input acquisition from flame detectors, gas sensors, and manual call points
Burner Management Systems (BMS) – monitoring flame detectors, air flow switches, and valve position feedback for safe boiler/furnace control
Turbine Control Systems – acquisition of critical shutdown signals and vibration sensors for gas/steam turbines
Process Safety Interlocks – monitoring level switches, temperature sensors, and pressure transmitters in chemical reactors
High Availability Process Control – SIL‑rated digital input acquisition for continuous production lines with zero tolerance for unplanned downtime
Triple Modular Redundancy (TMR) – each input channel has three independent measurement circuits with 2oo3 voting
IEC 61508 SIL 3 certified – TÜV approved for safety instrumented functions
40 high density TMR input channels – 40 independent triple‑redundant digital inputs per module
Comprehensive online diagnostics – real‑time monitoring of channel status, open/short circuits, stuck signals, and power supply anomalies
1 ms Sequence of Events (SOE) – high‑resolution timestamping for precise fault analysis and audit trails
Configurable line monitoring – per‑channel open‑circuit and short‑circuit detection independently configurable
Hot‑swap capability – online module replacement without system shutdown (requires companion slot or SmartSlot)
2500 V isolation barrier – robust galvanic isolation protects the backplane from field wiring disturbances
50/60 Hz digital filtering – per‑channel noise rejection eliminates spurious trips from industrial electromagnetic interference
Wide temperature range – operates from –40 °C to +70 °C for extreme environments
High‑integrity digital input acquisition – capture 24 Vdc discrete signals from field switches, pushbuttons, and proximity sensors, converting them into logic‑ready values for the safety controller
TMR fault masking – perform real‑time 2‑out‑of‑3 voting on three independent input measurements; any single faulty circuit is automatically excluded, and the remaining two circuits maintain correct output
Continuous self‑test and diagnostics – run periodic checks on input circuits, power rails, and communication interfaces; report faults via front‑panel LEDs and the I/O bus
Field wiring fault detection – detect open‑circuit and short‑circuit conditions on external cabling using independently configurable line monitoring thresholds
Sequence of Events (SOE) recording – log every input state change with a 1 ms timestamp for forensic analysis and post‑incident auditing
Noise rejection – apply software‑selectable 50 Hz or 60 Hz digital filtering to eliminate induced AC pickup from field cabling
Status indication – provide per‑channel operational status and module‑wide health indication via tri‑color LEDs
Online insertion and removal – support hot‑swap replacement in redundancy configurations, allowing a new T8403C to be installed without interrupting the safety function
Q1: What safety integrity level does the T8403C support?
A1: The T8403C is TÜV certified for IEC 61508 SIL 3 when used within the Trusted TMR safety system. Individual input channels also meet SIL 3 requirements.
Q2: Can the T8403C detect field wiring faults such as open or short circuits?
A2: Yes. The T8403C provides independently configurable line monitoring for each input channel, detecting open‑circuit and short‑circuit conditions on field cabling.
Q3: What is the resolution of the event sequence recording?
A3: The T8403C records Sequence of Events (SOE) with a 1 ms timestamp resolution, enabling precise fault diagnosis and post‑incident forensic analysis.
Q4: Can the T8403C be replaced while the system is running?
A4: Yes. The T8403C supports hot‑swap replacement when installed in a Trusted chassis with a companion slot or SmartSlot, allowing module exchange without system downtime.
Q5: Which termination assemblies are compatible with the T8403C?
A5: The T8403C interfaces with field wiring via Trusted I/O chassis backplane connectors. Compatible termination assemblies include the T8800 series Field Termination Assemblies (FTAs). Use of the correct FTA is required for proper signal conditioning.
