3601T Triconex Digital Input Module | SIL 3 Industrial Safety DI

Product Description

Overview

The Triconex 3601T is a high-reliability digital input module engineered for safety-critical industrial applications.
It acquires discrete signals from field devices such as switches, pushbuttons, and limit sensors.
Moreover, the module utilizes Triple Modular Redundancy (TMR) architecture to ensure fault-tolerant operation.
Its SIL 3 certification guarantees safety compliance for Emergency Shutdown (ESD), Fire & Gas (F&G), Burner Management Systems (BMS), and High-Integrity Pressure Protection Systems (HIPPS).
The 3601T supports continuous monitoring in harsh industrial environments while maintaining precise and reliable operation.
