4000056‑002 Triconex Digital Input Module | Safety Instrumented

Product Description

Overview

The Triconex 4000056‑002 is a high-performance digital input module designed for safety-critical industrial applications.
It acquires discrete signals from field devices including limit switches, pushbuttons, sensors, and contact closures.
Moreover, its Triple Modular Redundancy (TMR) architecture ensures continuous operation even if a channel experiences hardware failure.
Certified to SIL 3, the module is ideal for Emergency Shutdown (ESD), Fire & Gas (F&G), Burner Management Systems (BMS), and High-Integrity Pressure Protection Systems (HIPPS).
The module is built to withstand harsh industrial environments, providing reliable signal acquisition with high noise immunity.
