ICS T7411F Monitored Digital Input Module

Product Overview

The ICS Triplex T7411F is a high-reliability, monitored digital input module specifically engineered for the Regent and Regent+Plus control platforms. Now a part of the Rockwell Automation portfolio, this module is designed for mission-critical applications that require the highest levels of safety and availability. 

Technical Specifications

• Model Number: T7411F.

• Input Voltage: 24 VDC.

• Input Capacity: 16 Monitored Digital Input Channels.

• Safety Integrity Level: SIL 3 (IEC 61508) / DIN 19250 AK5.

• Voting Logic: Supports 1oo2 or 2oo3 configurations.

• Fault Detection: Dynamic input monitoring with automatic reporting.

• Operating Temperature: 0°C to 60°C.

• Weight: 6.62 lbs (3.0 kg).

• Environmental Limits: Up to 2000m altitude; 5% to 95% non-condensing humidity.

Key Features and Engineering Advantages

• Triple Modular Redundancy (TMR) Support: Integrated within Regent platforms to support 2oo3 voting, ensuring that a single component failure does not compromise the safety function or lead to a false trip.

• Dynamic Input Monitoring: The module performs continuous self-testing and field-side circuit monitoring to detect open circuits, short circuits, or stuck-at-faults in real-time.

• SIL 3 Safety Certification: Fully certified for use in Safety Instrumented Systems (SIS), meeting the rigorous demands of IEC 61508 for high-risk industrial processes.

• Automatic Fault Reporting: In the event of a detected irregularity, the T7411F immediately reports the diagnostic data to the central controller and logs the event for rapid troubleshooting.

• Robust 24V Logic: Designed for standard 24 VDC industrial field signals, providing reliable threshold detection and noise immunity.

• Harsh Environment Resilience: Built to operate reliably in a wide humidity range and at altitudes up to 2000 meters without requiring power derating.
