The TRICONEX 3805H Analog Output Module is a high-reliability industrial automation component designed for critical control applications.
Its key functions include:
1. Analog Signal Output
Provides 4-20 mA current output with +6% over-range capability for industrial field devices
Features 12-bit resolution and <0.25% full-scale accuracy (0-21.2 mA range)
2. Safety-Critical Performance
Implements Triple Modular Redundancy (TMR) architecture for fault tolerance
Continuously monitors output circuits with self-diagnostics and channel isolation
3. Industrial Reliability
Maintains specified accuracy across 0°C to 60°C operating range
Supports hot-swapping for online maintenance without system shutdown
4. Application Scope
Widely deployed in oil/gas, chemical, power generation, and other hazardous industries
Interfaces with field actuators like valve positioners and variable frequency drives
The module’s DC-coupled current loops and rugged design ensure stable signal transmission in electrically noisy environments.
Its voting logic allows continued operation even with two channel failures, making it suitable for Safety Instrumented Systems (SIS).
