Description
The ICS Triplex T3411F is a 16-channel monitored digital input module for use in safety-critical industrial control systems, particularly within the ICS Triplex / ICS Regent TMR (Triple Modular Redundant) architecture. It is used to acquire discrete field signals while continuously supervising both signal integrity and field wiring conditions.
Each of the 16 input channels accepts DC field signals typically in the range of 15 to 80 VDC, powered from an external 24–48 VDC field supply. The module internally regulates and conditions this supply to ensure consistent detection of switch states across all input points.
A defining feature of the T3411F is its continuous line monitoring capability. The module detects abnormal field conditions such as open circuits, short circuits, or wiring faults, and reports these diagnostics back to the controller. This allows both signal status and wiring integrity to be monitored in real time.

Wiring & Connections
Features:
- Sixteen input points, powered from external field supply
- Fault tolerant operation when connected in parallel withanother module of the same type
- Hot-replaceable
- Complete, automatic testing of all input circuits
The module processes 16 digital input signals from field devices including limit switches, proximity sensors, pushbuttons, and relay contacts. Each channel accepts either internally powered (wet) or passive (dry) contact inputs at 24 V DC nominal voltage, with an operating range of 18 to 30 V DC. Switching thresholds are defined as ≤ 8 V DC for the OFF state (turn-off) and ≥ 16 V DC for the ON state (turn-on). Input impedance is 3 kΩ typical, with a typical input current of 7 mA at 24 V DC.
The T3411F ICS Triplex Monitored Digital Input Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The T3411F implements Triple Modular Redundancy architecture, with each input channel processed in parallel by three completely independent circuits. An internal hardware voting mechanism eliminates any single hardware failure, ensuring the integrity and reliability of input signals. The module maintains operation in the presence of a single channel fault and provides continuous diagnostic coverage across all channels.
Channel-to-channel and system-to-field isolation is provided with a minimum rating of 500 V AC, preventing ground loop interference and protecting system electronics from field-side transients.
The module mounts in a designated slot of the ICS Triplex Trusted system rack and connects to field devices via a Field Termination Assembly (FTA) or Versatile Field Termination Assembly (VFTA). SmartSlot Link interfaces (A, B, C) provide TMR communication paths to the main processor modules. Hot-swap capability permits replacement without system shutdown.
- ESD: Monitors critical sensors and emergency trip buttons
- Oil/Gas Refineries: Used for fault-tolerant monitoring of hazardous processes
- Chemical Processing: Controls precise and risky chemical delivery and safety loops
- Power Generation: Manages safety-critical equipment like gas turbines with rapid fault detection
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Field Connections: The module connects to field devices via standard Field Terminal Assemblies (FTAs) or pre-assembled cables mapping directly to the chassis/backplane.
Power: It draws field power from an external supply to support the 16 input points and provides a minimum of 2500 V electrical isolation between field and logic circuits.
Configuration: In the engineering software (such as ICS Regent or Regent+Plus), ensure you set the module type to T3411F and edit the module definition to match your specific I/O and fault-tolerance requirements.
Technical notes
The module is designed with high electrical isolation (up to 2500 V) between field wiring and logic circuits, ensuring stable operation in electrically noisy industrial environments. Input states are processed through internal comparators and monitoring circuits, enabling fast and deterministic response behavior typically within 10 ms switching time.
