TRICONEX 3806E 9720051-00
High-Reliability Analog Output Module for Safety-Critical Industrial Automation
High-Reliability Analog Output Module for Safety-Critical Industrial Automation
Product Overview
The TRICONEX 3806E 9720051-00 is a high-performance analog output module engineered for industrial automation systems requiring precision, safety, and uninterrupted operation. As a core component of the TRICONEX Tricon safety instrumented system (SIS), this module delivers reliable signal conditioning and control for critical processes in industries such as oil & gas, chemical processing, and power generation. The TRICONEX 3806E 9720051-00 is designed to convert digital signals from the Tricon controller into analog outputs (4–20 mA or 20–320 mA), enabling precise actuation of valves, motors, and other field devices in safety-critical applications certified to Safety Integrity Level 3 (SIL 3).
With 8 isolated output channels and a 12-bit resolution, the TRICONEX 3806E 9720051-00 ensures accurate signal transmission even in harsh industrial environments. Its triple modular redundancy (TMR) architecture—featuring three independent processing channels and a voting mechanism—eliminates single points of failure, ensuring continuous operation in the presence of component faults. The module’s built-in diagnostics monitor signal integrity, wiring continuity, and module health in real time, providing actionable alerts to prevent unplanned downtime. By integrating seamlessly with TRICONEX termination boards and communication modules, the TRICONEX 3806E 9720051-00 forms a robust foundation for emergency shutdown systems (ESD), burner management systems (BMS), and high-integrity pressure protection systems (HIPPS).
