ICS Triplex |T7481|Guarded Output Module

Rockwell Automation ICS TRIPLEX T7481 Input/Output Module

The ICS TRIPLEX T7481 is a guarded digital output module designed for safety-related applications.

Features

• Provides fail-safe and fault-tolerant operation
• Supports 1oo1 (single module) or 2oo2 (dual modules) configurations
• Operates at 24V DC supply voltage
• Offers dynamic output transition monitoring

Technical Specifications

• Voltage Rating

  • 24V DC nominal

• Safety Certification

  • Certified for de-energize to trip configuration
  • Can be used in energize to trip applications under defined conditions

• Configuration Options

  • Fail-safe single module (1oo1)
  • Fault-tolerant dual modules (2oo2)

• Dynamic Transition Requirement

  • Outputs must transition between logic states (0→1→0 or 1→0→1) at intervals not exceeding the SFOC (Safe Failure Operating Cycle)

• Fault Detection

  • Fault detection period must be less than process safety time
  • Failed outputs must be replaced within the second fault occurrence period

• Operational Conditions

  • Must be used with application logic that forces outputs to a safe state upon error detection
  • Error bit latching required with manual reset after fault clearance

• Certification Standards

  • Complies with DIN19250/AK5
  • Non-interfering with Trusted TMR Controller

• System Integration

  • Designed for use with Regent and Regent+Plus Low Density I/O systems
  • Optimized for short test intervals to maintain system safety availability
