Technical Specifications

Key Features and Advantages

The Triconex 3625 delivers exceptional reliability through its patented TMR architecture that provides continuous fault detection and correction. Each output channel features independent diagnostics with real-time status reporting to the control system. The module’s supervised outputs verify both open and short circuit conditions, ensuring complete loop integrity. Safety compliance: The 3625 meets SIL 3 safety requirements according to IEC 61508 and IEC 61511 standards. Its hot-swappable design allows for module replacement without system shutdown, minimizing downtime in critical processes. The module’s industrial-grade construction withstands severe vibration and electromagnetic interference common in industrial environments.

Application Fields

The Triconex 3625 is extensively used in safety-critical applications across multiple industries. In oil and gas facilities, it provides emergency shutdown (ESD) functionality for wellheads and processing units. The power generation industry utilizes the 3625 for turbine protection systems and boiler safety controls. Chemical plants deploy this module for reactor shutdown systems and fire/gas detection applications. The 3625 also serves critical functions in pharmaceutical manufacturing where batch process safety is essential. Its high reliability makes it ideal for offshore platforms and other remote installations where maintenance access is limited.

Installation and Maintenance

Installation preparation: Before installing the Triconex 3625, verify proper slot alignment in the Triconex chassis and ensure adequate clearance for ventilation. Prepare appropriate wiring with proper gauge and insulation for the intended load requirements. Confirm that all system power is disconnected during module installation.
