TRICONEX DO3401 DCS MODULE NEW BRAND

TRICONEX DO3401 Digital Output Module: Overview and Technical Specifications
1. Product Overview
The TRICONEX DO3401 is a high-integrity digital output module designed for safety-critical applications in industrial automation systems, manufactured by TRICONEX (now part of Schneider Electric) . As a key component of the Triconex Trident safety instrumented system (SIS) and Tricon system, it provides a fault-tolerant interface between control systems and field devices such as valves, actuators, and pumps. The module is specifically engineered for use in emergency shutdown systems (ESD), fire and gas systems (F&G), and burner management systems (BMS) in industries including oil and gas, chemical, power generation, and pharmaceuticals. It features a triple modular redundant (TMR) design, advanced diagnostic capabilities, and solid-state relay outputs to ensure reliable operation in harsh industrial environments. The DO3401 is certified for SIL3 (Safety Integrity Level 3) compliance, meeting IEC 61508 and IEC 61511 safety standards.
