TRICONEX 3504E | high-density digital input module

Core Function & Technical Overview

Functionality

• Triple Modular Redundancy (TMR): Three independent processing channels ensure continuous operation even in the presence of single-point failures
• High-Density Design: Supports 64 digital input channels in a compact form factor, reducing system complexity and cost
• Wide Voltage Range: Accepts 24–55 VDC inputs for compatibility with diverse industrial sensors

Technical Specifications

Key Design Features

1. TMR Architecture:
• Each channel includes an 8-bit microprocessor for independent signal processing and fault detection
• 2-out-of-3 voting ensures data integrity by resolving discrepancies between channels
2. Non-Isolated High-Density Design:
• Optimized for cost-sensitive applications where isolation is not required, reducing module count and system complexity
• Supports hot-swap functionality for online replacement without process downtime
3. Rugged Industrial Performance:
• IP66/NEMA 4X enclosure provides protection against dust and water ingress in harsh environments
• Shock/vibration resistance (15G vibration, 2G shock) ensures reliability in high-motion settings
4. Comprehensive Diagnostics:
• Continuous self-testing for stuck-on/stuck-off faults with <500 μs detection time
• Fault indicators for individual channels and module-level status
