Product Overview
The TRICONEX 3626X is a next-generation digital output module designed for TRICONEX’s Tricon triple-modular redundant (TMR) safety instrumented systems (SIS), delivering advanced actuation control in mission-critical industrial environments. Built on TRICONEX’s proven TMR architecture, this module serves as the interface between controllers and field devices, converting processed signals into reliable outputs for valves, motors, and solenoids. Its design prioritizes safety, durability, and adaptability, making it ideal for applications where uninterrupted operation is essential.
Featuring 16 configurable 24V DC sinking/sourcing channels, the TRICONEX 3626X supports high-density actuation requirements while maintaining fail-safe integrity. Its rugged construction withstands extreme temperatures (-40°C to 70°C), vibration, and electromagnetic interference (EMI), ensuring consistent performance in harsh conditions. SIL 3 certification (IEC 61508) and ATEX compliance validate its suitability for explosive atmospheres, such as those found in oil & gas refineries or chemical processing plants. The module’s diagnostic capabilities provide real-time insights into output health, load status, and redundancy performance, enabling proactive maintenance and minimizing downtime. By combining redundancy, precision, and scalability, the TRICONEX 3626X empowers industries to safeguard assets, personnel, and processes.
Technical Specifications
Key Features and Benefits
The TRICONEX 3626X’s TMR architecture ensures continuous operation by processing signals through three independent channels, eliminating single points of failure. This redundancy is critical in safety systems, where a single fault could compromise emergency shutdowns or cause unintended equipment activation. The module’s 3A per channel output rating exceeds industry standards, allowing it to directly drive high-power actuators without intermediate relays, reducing system complexity and failure points.
Its enhanced diagnostic capabilities provide granular insights into output performance, including load current anomalies and channel discrepancies. These diagnostics integrate seamlessly with TRICONEX’s system software, enabling predictive maintenance and reducing unplanned downtime. The module’s ATEX certification makes it suitable for hazardous areas, while its short-circuit and surge protection safeguards both the module and connected devices from transient faults. With a faster response time (<8ms), the TRICONEX 3626X ensures near-instantaneous actuation in time-sensitive applications like pressure relief valve control.
The TRICONEX 3626X also supports hot-swappable replacement, allowing maintenance without disrupting system operation. This feature, combined with its wide temperature range and rugged enclosure, ensures reliability in extreme industrial environments. By combining advanced diagnostics, high-power capacity, and redundant design, the TRICONEX 3626X sets a new standard for safety and efficiency in digital output modules.
Application Scenarios
The TRICONEX 3626X excels in industries where precise, fail-safe actuation is non-negotiable. In offshore oil platforms, it controls emergency shutdown valves (ESDVs) to isolate pipelines during leaks or fires, leveraging its ATEX certification to operate safely in explosive atmospheres. Its 3A output capability directly drives large hydraulic solenoids, eliminating the need for external amplifiers.
In chemical manufacturing, the module manages reactor isolation valves and agitator motors, ensuring compliance with batch control recipes. Its TMR redundancy is particularly valuable in polymerization processes, where output failures could lead to reactor overpressure or product contamination. Power generation facilities use the TRICONEX 3626X to actuate turbine bypass valves and boiler feedwater pumps, maintaining stable power output during load fluctuations. Its fail-safe design ensures these systems default to safe states during faults, aligning with nuclear and thermal plant safety protocols.
Mining operations benefit from the module’s rugged design, using it to control conveyor belt motors and slurry pumps in high-vibration environments. The
TRICONEX 3626X’s diagnostic depth and ATEX compliance also make it ideal for managing gas detection systems in underground mines, where reliability is critical to worker safety.

Installation and Maintenance
Installing the TRICONEX 3626X requires integration into a Tricon chassis with compatible backplane connectors, ensuring secure mechanical and electrical coupling. The module should be mounted in a clean, dry enclosure with adequate ventilation to maintain operating temperatures within -40°C to 70°C. Proper grounding is essential to minimize EMI interference, and wiring should follow TRICONEX’s guidelines to ensure correct polarity and prevent short circuits. Before powering up, verify that the module’s output configuration matches the load requirements of connected devices, including voltage, current, and sinking/sourcing type.
For maintenance, conduct quarterly checks using TRICONEX’s diagnostic software to verify output integrity and redundancy status. Visually inspect terminals for corrosion or looseness, and clean them gently if necessary. Test output channels annually by simulating control signals to confirm proper actuation of field devices. While the TRICONEX 3626X has a long service life (MTBF >2,000,000 hours), consider replacement every 10–12 years in high-stress applications to maintain optimal performance. Always power down the Tricon system before servicing the module to avoid electrical hazards or data corruption.
