TRICONEX 3805E Analog Output Module – Functions & Features
1. Primary Functions
Analog Signal Output:
Converts digital signals into 4-20mA/0-10V analog outputs to control actuators, valves, and other field devices.
Supports 8 independent channels with 12-bit resolution for precise control in industrial processes.
Triple Modular Redundancy (TMR):
Implements TMR technology to ensure fault tolerance by voting on three processor outputs and selecting a healthy signal.
2. Key Features
High Reliability & Safety:
Complies with SIL standards for critical applications like Emergency Shutdown (ESD) and Fire & Gas systems.
Continuous self-diagnostics detect faults (e.g., open circuits, channel failures) and deactivate faulty channels automatically.
Flexible Configuration:
Each channel can be independently configured for voltage or current output.
Hot-swappable design allows online replacement without system downtime.
3. Typical Applications
Process Control:
Drives valve positioners, variable frequency drives (VFDs), and pumps in oil/gas, power plants, and chemical industries.
Safety Systems:
Integrates with Triconex SIS for fail-safe control in hazardous environments.
4. Technical Specifications
Resolution: 12-bit (programmable for high precision).
Isolation: Channel-to-channel and system isolation to reduce interference.
Indicators: LED status lights (LOAD, PWR1/PWR2) for real-time monitoring.
