Product Description
The Triconex 3504E is a high-density digital input module designed for the Tricon Triple Modular Redundancy (TMR) safety platform. Supporting 64 discrete input points, this module is ideal for large-scale Safety Instrumented Systems (SIS) where cabinet space and high channel density are critical.
Equipped with advanced internal diagnostics, the 3504E continuously monitors each input to detect “stuck-on” or “stuck-off” faults within milliseconds, ensuring reliable and safe operation of high-integrity process control loops.
Key Features
-
64-point, high-density digital input for compact, efficient monitoring
-
Software-selectable voltage: 24 VDC or 48 VDC via TriStation 1131
-
Fault-tolerant 2-out-of-3 (2oo3) voting logic across three isolated channels
-
Integrated self-tests (“Stuck Test”) for ON and OFF states
-
Commoned 64-point design maximizes slot efficiency
-
Ideal for Emergency Shutdown (ESD), Burner Management Systems (BMS), and high-volume status monitoring
