TRICONEX 2401S2 Product Specification
Product Overview
The TRICONEX 2401S2 is a high-reliability digital output module designed for TRICONEX’s Triple Modular Redundant (TMR) safety instrumented systems (SIS). Engineered to deliver fail-safe control in critical industrial processes, this module translates digital signals from the system’s logic solver into precise actuation commands for valves, motors, and other field devices. As part of TRICONEX’s TMR platform, the TRICONEX 2401S2 ensures continuous operation even in harsh environments, making it essential for applications where downtime risks catastrophic consequences, such as oil refineries, chemical plants, and nuclear power facilities.
Featuring 24 individually configurable output channels, the TRICONEX 2401S2 supports both sinking and sourcing logic, allowing seamless integration with a wide range of industrial actuators. Each channel is rated for 24 VDC and 2 A, ensuring robust performance in high-demand scenarios. The module’s TMR architecture—three independent processing paths—guarantees redundancy, with automatic fault isolation and graceful degradation to maintain system integrity during single-channel failures. This redundancy is critical for safety-critical applications like emergency shutdown (ESD) systems, where a single point of failure could compromise personnel safety or equipment .
Built to withstand extreme conditions, the TRICONEX 2401S2 operates reliably between -40°C and +70°C and supports humidity levels up to 95% non-condensing. Its compact design (259 mm × 160 mm × 79 mm) and lightweight construction (1.0 kg) facilitate easy installation in standard 19-inch racks, while its hot-swappable design enables maintenance without system downtime. Certified to IEC 61508 SIL 3, the TRICONEX 2401S2 meets the highest safety standards, ensuring compliance with global regulations for risk mitigation in process industries .

Main Features and Advantages
Triple Modular Redundancy (TMR): The TRICONEX 2401S2 employs three independent processing channels, each with its own power supply and logic circuits. If one channel fails, the other two continue operation, ensuring zero interruption to critical outputs. This architecture is vital in nuclear power plants, where a single channel failure could disable reactor cooling systems .
SIL 3 Compliance: Designed to meet IEC 61508 SIL 3 standards, the TRICONEX 2401S2 minimizes the probability of dangerous failures, making it suitable for applications with high risk exposure, such as offshore platform ESD systems .
Harsh Environment Resilience: With an operating temperature range of -40°C to +70°C and IP66 protection against dust and water ingress, the TRICONEX 2401S2 performs reliably in extreme conditions, including desert oil fields and arctic LNG terminals .
Flexible Configuration: The 24 configurable output channels support both sinking and sourcing logic, allowing seamless integration with diverse actuators. This flexibility is critical in chemical processing plants, where valves and pumps from multiple vendors require varied control signals .
Hot-Swap Capability: The TRICONEX 2401S2 can be replaced while the system remains operational, reducing maintenance downtime by up to 90% compared to non-hot-swappable modules. This feature is essential in continuous-process industries like pharmaceuticals, where production halts are costly .
Installation and Maintenance
Pre-installation Preparations: Before installing the TRICONEX 2401S2, verify the input voltage (24 VDC) from a compatible power supply (e.g., TRICONEX 3700A). Clean the rack slot and ensure proper alignment with the backplane connectors. Secure the module using captive screws and tighten all terminal block connections to prevent loose contacts .
Maintenance Suggestions: Inspect the TRICONEX 2401S2 monthly for signs of overheating, corrosion, or physical damage. Use a dry cloth to remove dust from the module’s surface and vents. Quarterly, simulate a channel fault using TRICONEX’s diagnostic tools to verify redundancy functionality. If fault indicators persist, replace the module promptly to avoid cascading failures .
