The TRICONEX 3806E Analog Output Module (AO3806E) is a safety-critical industrial control component with the following key functions and features:
1. Triple Modular Redundancy (TMR) Architecture
Implements 3-channel redundancy for fault-tolerant analog signal output (4-20 mA)
Continues operation even if two channels fail, ensuring high availability
2. Precision Analog Output
Delivers 8 independent current outputs (4-20 mA) with self-calibration
Features continuous diagnostics for signal accuracy and loop integrity
3. Advanced Diagnostics & Safety
Monitors output circuits via current loopback verification
Activates alarms for faults (e.g., open-loop conditions) while isolating defective channels
4. Industrial Applications
Deployed in ESD (Emergency Shutdown) systems and hazardous environments (oil/gas, chemical plants)
Compatible with actuators like valve positioners and variable frequency drives
5. Robust Design
Supports hot-swapping for maintenance without system downtime
Operates reliably in harsh conditions (e.g., electrical noise, wide temperature ranges)
The module’s TMR voting logic and fail-safe mechanisms make it ideal for Safety Instrumented Systems (SIS).
