TRICONEX 3664 Dual Digital Output Module
Product Overview
The TRICONEX 3664 is a high-reliability dual digital output module engineered for safety-critical industrial applications, particularly in Safety Instrumented Systems (SIS) and Emergency Shutdown (ESD) systems. As part of TRICONEX’s Trident series, this module leverages a 2oo3 (2-out-of-3) voting architecture to ensure fault tolerance and SIL 3 compliance, making it ideal for environments where system integrity is non-negotiable, such as oil refineries, chemical plants, and power generation facilities . Each of its two isolated output channels supports 2A of current, enabling direct control of high-power devices like solenoid valves, actuators, and motor starters, while maintaining precise signal integrity under extreme conditions .
Designed with hot-swappable capabilities, the TRICONEX 3664 allows for module replacement without system downtime, minimizing maintenance disruptions. Its compact form factor (120 mm x 80 mm x 60 mm) and lightweight construction (0.5 kg) facilitate easy integration into space-constrained control panels, while compliance with CE, UL, and SIL 3 certifications guarantees operation in hazardous and high-risk environments . The module’s advanced diagnostics continuously monitor channel health, detecting faults such as open circuits or voltage irregularities within milliseconds and triggering real-time alerts to prevent cascading failures .
By combining dual redundancy with TRICONEX’s proven Triple Modular Redundancy (TMR) technology, the 3664 achieves a Mean Time Between Failures (MTBF) exceeding 200,000 hours, ensuring long-term operational stability. Whether used in standalone safety loops or integrated into distributed control systems (DCS), this module delivers unparalleled performance, scalability, and ease of integration, making it a cornerstone of modern industrial automation .

Main Features and Advantages
Safety-Critical Redundancy: The TRICONEX 3664 employs a 2oo3 voting mechanism, where three independent processing channels continuously validate output signals. If one channel fails, the module automatically switches to a dual-channel configuration, ensuring uninterrupted operation. This architecture is certified for SIL 3 applications, meeting the strictest safety standards in industries like nuclear power and offshore drilling .
High-Power Output Capability: With 2A per channel, the module directly drives high-power devices without external amplifiers, reducing system complexity and costs. Its dual redundant output circuits further enhance reliability by providing backup paths for critical control signals .
Real-Time Diagnostics: Built-in self-testing monitors each channel for faults, including short circuits, open circuits, and voltage deviations. Faults are reported via status LEDs and integrated system diagnostics, enabling proactive maintenance and minimizing Mean Time to Repair (MTTR) .
Flexible Integration: The 3664 supports industry-standard communication protocols like Modbus TCP/IP and OPC UA, allowing seamless integration with existing DCS, SCADA, and HMIs. Its compatibility with TRICONEX’s TRICON CX platform ensures unified control and monitoring across distributed systems .
Hazardous Environment Compliance: Rated for operation in temperatures from -20°C to +60°C and humidity up to 95% non-condensing, the module is suitable for harsh industrial environments. Its CE and UL certifications further validate its robustness in challenging conditions .
