Triconex 3361 24 VDC TMR 32-Point Digital Input Module

Description

The 3361 is a high-integrity Digital Input (DI) module specifically engineered for the Tricon Triple Modular Redundant (TMR) safety system. This module provides 32 isolated input channels designed to interface with 24 VDC field contacts in Safety Instrumented Systems (SIS). By utilizing three independent processing paths, the module ensures that a single component failure does not compromise the safety function or cause a nuisance trip. Each input signal is voted upon at the hardware level, providing the extreme reliability required for SIL 3 rated applications. This module is the industry standard for monitoring critical process states where signal accuracy is the highest priority.
