Description

The 3504E is a high-density digital input (DI) module designed for safety-critical applications. It features triple-modular redundancy (TMR) to ensure maximum availability and safety. The module continuously verifies the ability of the Tricon system to detect state transitions, with all critical signal paths 100% triplicated.

Features

High Density: 64 points per module
Triple-Modular Redundancy (TMR): Ensures operation in the presence of single faults
Voltage Options: 24 VDC or 48 VDC (selected via TriStation software)
Enhanced Diagnostics: Continuous self-tests for stuck-ON and stuck-OFF conditions
Hot-Spare Support: Ensures continuous operation during failures
Mechanical Keying: Prevents improper installation
Diagnostic Indicators: PASS, FAULT, ACTIVE status per point
