TRICONEX 3624 16-Channel 24 VDC Supervised Digital Output Module (TMR) for Tricon SIL 3 SIS

Product Description

The TRICONEX 3624 is a high-integrity Triple Modular Redundant (TMR) 16-channel supervised digital output module, engineered by TRICONEX (Schneider Electric, former Invensys) for SIL 3 safety instrumented systems (SIS) in critical industrial environments. As a core safety signal execution component, this hot-swappable module (supplied as a TMR set of 3) is designed to drive discrete safety actuators (solenoid valves, alarm horns, trip relays) via 24 VDC commoned sinking outputs with voltage/current loopback monitoring, field circuit diagnostics, and load detection. It features channel-level self-protection, TMR majority voting, and seamless integration with Tricon/Tricon CX chassis—making it ideal for emergency shutdown (ESD), fire & gas (F&G), and process safety systems in oil & gas, chemical, petrochemical, and power generation industries.

Key Functions

The 3624 supervised digital output module delivers fault-tolerant, TMR-voted discrete signal execution with full loop diagnostics for safety-critical applications. Key functions include: 16 independent commoned sinking digital output channels (24 VDC nominal, 16–30 VDC range, max 36 VDC); supervised output mode with voltage and current loopback circuitry for output circuit verification; field circuit monitoring (open/short/overload) and load detection (min 30 mA load); TMR majority voting (2-out-of-3) for output integrity; hot-swappable design for online maintenance without system shutdown; LED status indicators for module health (PASS/FAULT/POWER), channel active status, and load detection; and compatibility with Tricon/Tricon CX main/expansion chassis.

Application Scenarios

The TRICONEX 3624 supervised digital output module is deployed in safety-critical industrial applications requiring high-integrity discrete signal execution with full loop diagnostics and SIL 3 compliance. In offshore oil & gas platforms and refineries, it drives ESD solenoid valves, fire alarm horns, and emergency isolation valves to trigger safety shutdowns, with real-time diagnostics to detect field wiring faults. For chemical and petrochemical plants, it controls reactor trip relays, toxic gas mitigation system actuators, and emergency vent valves, ensuring coordinated safety actions and compliance with IEC 61508/61511 standards. In power generation facilities, it connects turbine/generator trip relays, breaker control circuits, and cooling system actuators to Tricon SIS, supporting regulatory compliance and operational reliability. The module is also used in mining, pharmaceutical, and water/wastewater treatment—all scenarios where secure, high-availability discrete signal execution with loop diagnostics is mandatory.
