TRICONEX 7400206-100 Digital Output Module

Description

Product Detail: TRICONEX 7400206-100 Digital Output Module

Overview

The TRICONEX 7400206-100 is a high-reliability Digital Output Module designed for the Triconex® TRICON safety instrumented system (SIS). This module provides robust, fault-tolerant digital output control for critical safety applications in process industries. As part of Triconex’s triple modular redundant (TMR) architecture, it ensures continuous operation and functional safety integrity level (SIL 3) compliance by utilizing three independent output channels per point. The module is engineered for demanding environments where failure is not an option, making it ideal for emergency shutdown (ESD), fire and gas (F&G), and other safety-critical systems.

Key Features & Benefits

• Triple Modular Redundancy (TMR): Employs three independent output channels per point with continuous voting and diagnostics to ensure fault-tolerant operation.

• High Reliability: Designed for critical safety applications with built-in diagnostics for output validation, short-circuit protection, and load monitoring.

• Hot Swap Capability: Supports online module replacement without system shutdown, minimizing downtime in continuous processes.

• Flexible Output Configuration: Supports both sinking and sourcing outputs with configurable output voltages (e.g., 24 VDC, 48 VDC).

• SIL 3 Certified: Complies with IEC 61508 and IEC 61511 standards for functional safety in safety instrumented systems.

• Seamless Integration: Fully compatible with TRICON v9, v10, and v11 systems and programmable via TriStation™ 1131 software.
