Description
The T3411 is a 16-channel monitored digital input module from the ICS Triplex Trusted TMR (Triple Modular Redundancy) system family, manufactured by ICS Triplex (now Rockwell Automation). It is designed for safety-critical industrial automation applications requiring high-integrity input signal acquisition.
The module provides 16 monitored digital input channels, each capable of interfacing with both internally powered (wet) and passive (dry) contact field devices. The nominal input voltage is 24 V DC with an operational 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.
Each channel incorporates built-in line monitoring functionality, enabling automatic detection of wiring faults including open circuits, short circuits, and ground faults. This monitoring capability ensures the integrity of field wiring and provides early warning of potential system failures.

Field Wiring and Connection
Features:
- 16 monitored digital input channels
- Nominal 24 VDC input operation
- Field supply range of 15–80 VDC
- Automatic open-circuit and short-circuit detection
The module supports 16 independent 24 VDC digital input channels powered from an external field supply ranging from 15 to 80 VDC. An internal regulator converts the incoming field supply to 24 VDC for the input interface circuitry, ensuring consistent operation across a wide range of industrial power sources.
The T3411 ICS Triplex 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 module performs continuous automatic self-diagnostics on all input circuits during operation. Individual front-panel LEDs display input status, line fault conditions, module health, power status, and active/fault indications, allowing rapid troubleshooting without interrupting the control system. The module is also hot-replaceable, enabling replacement while the system remains operational.
For high-availability applications, multiple T3411 modules can operate in parallel redundant configurations, allowing fault-tolerant input processing. Electrical isolation of at least 2500 V between the field wiring and internal logic helps protect the controller from electrical disturbances and improves reliability in harsh industrial environments
- Oil & Gas: Used in upstream, downstream, offshore, and pipeline networks
- Power Generation: Used in nuclear, thermal, and hydro plants for boiler/turbine/generator safety
- Chemical Processing: Deployed for batch safety and hazardous asset monitoring in volatile environments
- Fire & Gas Detection: Tracks flame/smoke/toxic sensors to trigger deluge, ventilation, or area sealing
- Process Interlocking: Evaluates pressure/temperature/level switches to isolate equipment beyond safe limits
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 Terminals: Field wiring for the 16 input points connects via a pre-wired termination assembly or field terminal block (FTB) at the rear of the chassis, rather than directly to the module board itself.
Input Type Setup: The T3411 supports both internally powered (wet) and passive (dry) field contacts. The module operates on a nominal 24 VDC supply (with an operational range of 18-30 VDC).
Line Monitoring: To ensure fault tolerance and open/short circuit monitoring, a line monitor device is typically required at the field switch. This monitors loop integrity, sending a signal back to the controller's application logic.
Technical notes
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 online replacement without system shutdown.
FAQs
