Product Overview
The TRICONEX 2401H is a high-reliability digital output module designed for integration into TRICONEX safety instrumented systems (SIS), providing precise control of field devices in safety-critical industrial applications. As part of TRICONEX’s advanced I/O module portfolio, the 2401H is engineered to deliver stable signal transmission and electrical isolation, ensuring robust performance in emergency shutdown systems (ESD), fire-and-gas detection networks, and process control loops.
Featuring 24 isolated output channels, the 2401H interfaces with actuators such as solenoid valves, relays, and motor starters, converting digital commands from TRICONEX controllers into physical actions. Its 24V DC output voltage and 2A per-channel current rating support a wide range of industrial devices, while 2,500Vrms electrical isolation safeguards the system from voltage transients and electromagnetic interference (EMI). The module’s compatibility with TRICONEX’s triple modular redundancy (TMR) architecture—including Tricon and TriconEX platforms—ensures seamless integration into SIL 3-compliant systems, where fault tolerance and continuous operation are paramount. By combining real-time control with diagnostic feedback, the 2401H plays a pivotal role in maintaining operational safety and minimizing downtime in high-risk environments.

2401H
Main Features and Advantages
High-integrity control: The 2401H’s 24 isolated channels support simultaneous actuation of diverse field devices, ensuring rapid response to safety-critical events. Its 2A per-channel current capacity handles demanding loads such as heavy-duty solenoid valves, while quad voter circuitry (patented by TRICONEX) ensures fault-tolerant operation by requiring two-out-of-three channel agreements to activate outputs.
Electrical robustness: With 2,500Vrms isolation and surge protection, the module withstands harsh industrial conditions, including voltage spikes and EMI common in petrochemical plants and power generation facilities. This resilience minimizes unplanned shutdowns and extends the lifespan of connected equipment.
Diagnostic capabilities: Built-in status indicators and real-time fault monitoring provide actionable insights into module health. Features like open-load detection and short-circuit protection enable proactive maintenance, reducing troubleshooting time and optimizing system uptime.
Ease of integration: The 2401H is designed for plug-and-play installation in TRICONEX Tricon and TriconEX racks, requiring no specialized tools. Its compact form factor maximizes space efficiency in control cabinets, making it suitable for retrofitting existing systems.
SIL 3 compliance: Engineered to meet the highest safety integrity standards, the 2401H ensures reliable performance in applications where failure could lead to catastrophic consequences, such as offshore oil platforms and chemical reactors.
Installation and Maintenance
Pre-installation preparations: Before installing the 2401H, verify compatibility with the target TRICONEX chassis (e.g., TriconEX main or expansion racks). Ensure the input voltage matches the module’s requirements and that the mounting location provides adequate ventilation. Inspect terminal blocks for damage and confirm proper grounding of the system. Power off the controller and disconnect all power sources before handling the module to prevent electrical hazards.
Maintenance suggestions: Conduct quarterly checks of the module’s output signals using a multimeter to ensure they align with expected values. Clean dust from ventilation slots to prevent overheating, and inspect terminal connections for corrosion or looseness. Monitor diagnostic indicators for fault conditions; a red LED indicates a critical issue requiring immediate attention. In redundant configurations, test channel redundancy annually to confirm failover functionality. Replace the module if any channels exhibit persistent signal irregularities.
Application Fields
The TRICONEX 2401H excels in industries where safety and reliability are non-negotiable:
- Oil and gas: Activates emergency shutdown valves on offshore rigs and refineries, isolating hazardous areas during leaks or equipment failures.
- Chemical processing: Controls reactor agitators, pressure relief valves, and fire suppression systems to prevent explosions and chemical spills.
- Power generation: Manages turbine bypass valves and boiler safety interlocks, ensuring stable operation of power plants and minimizing downtime.
- Pharmaceuticals: Enforces sterile environment protocols by controlling cleanroom access doors, HVAC systems, and sterilization equipment.
In each sector, the 2401H serves as a foundational component for maintaining operational continuity, protecting personnel and assets from catastrophic events.
