TRICONEX Launches DI3361 High-Density Digital Input Module for Enhanced Safety System Integration
Houston, Texas – TRICONEX, a Schneider Electric company specializing in mission-critical industrial safety solutions, has introduced the DI3361 Digital Input Module, a high-performance component designed to improve reliability and scalability in Safety Instrumented Systems (SIS) across energy, chemical, and manufacturing sectors.

The DI3361, part of the Triconex® TriStation™ platform, provides 32 configurable digital input channels, doubling the density of previous-generation modules while maintaining SIL 3 (Safety Integrity Level 3) compliance under IEC 61508 standards. Engineered for harsh environments, the module ensures precise monitoring of safety-critical signals, such as emergency shutdown triggers and pressure alarms, with minimal risk of false diagnostics or system downtime.

Key Technical Advancements
The DI3361 incorporates galvanic isolation across all channels, eliminating cross-talk and voltage surges in electrically noisy installations. Its advanced diagnostics detect faults in real time, including open circuits, short circuits, and signal degradation, reducing mean time to repair (MTTR) by up to 30%. The module also supports HART protocol communication, enabling seamless integration with smart field devices for predictive maintenance and data-driven decision-making.

Built to operate in temperatures ranging from -40°C to 70°C, the DI3361 is ideal for extreme conditions in offshore rigs, petrochemical plants, and mining operations. Enhanced cybersecurity features, such as secure firmware validation and tamper-evident hardware design, align with IEC 62443 standards to mitigate risks from cyber-physical threats.

Market Impact
As industries face tightening safety regulations and aging infrastructure upgrades, the DI3361 addresses growing demand for modular, high-availability components. Pilot deployments in North American gas processing facilities have reported a 25% improvement in signal accuracy and a 15% reduction in commissioning costs compared to legacy systems. Industry analysts project the global market for industrial safety modules to grow at a 6.5% CAGR through 2032, driven by digitalization and risk management priorities.

Availability and Compliance
The TRICONEX DI3361 is now available globally through authorized distributors. The module meets ATEX, IECEx, and NEC certifications for use in hazardous locations, with optional custom configurations for nuclear and marine applications.
