Triconex DI232 | 32-Channel Digital Input Module for SIS

Product Description

Overview

The Triconex DI232 is a high-integrity digital input module designed to interface discrete field devices with the Triconex Safety Instrumented System (SIS).
It converts signals from push buttons, limit switches, contact closures, and indicators into logic inputs for safe and reliable processing.
Built on Triple Modular Redundancy (TMR) architecture, the DI232 provides fault tolerance, continuous operation, and SIL 3 compliance.
Moreover, it is engineered for demanding industrial environments, ensuring robust performance in oil & gas, chemical, petrochemical, and power generation applications.
