Product Overview

The Triconex 3806E acts as a high-integrity Analog Output Module designed for the most demanding Safety Instrumented Systems (SIS). This 100% Brand New original module utilizes a Triple Modular Redundancy (TMR) architecture to provide fault-tolerant control of critical field actuators. Unlike standard analog cards, the 3806E offers a unique mixed-output configuration, combining conventional 4-20 mA signals with specialized 20-320 mA high-current outputs. This dual-capability makes it the industry standard for governing hydraulic actuators in turbomachinery and complex process safety loops where precision and power must coexist.

Engineering Advantages

Dynamic Mixed-Signal Support: The 3806E eliminates the need for separate high-power modules by integrating six standard 4-20 mA loops and two 20-320 mA loops. This allows engineers to control standard control valves and high-demand torque motors or hydraulic positioners from a single module slot.
Triple Modular Redundant Fault Tolerance: Three independent internal processing legs vote on every output signal. If one path fails, the 2oo3 (two-out-of-three) voting logic ensures the remaining two legs maintain control without an output glitch, preventing costly nuisance trips in turbomachinery.
Extreme Environment Resilience: Engineered for survival, the module operates reliably from -40 °C to +70 °C. This ruggedized design suits remote oil and gas installations and power generation facilities where temperature control in equipment shelters may vary.
High-Precision Actuator Command: The 16-bit internal resolution provides the granular control necessary for anti-surge valves and fuel gas regulators. This precision directly translates to better process stability and reduced mechanical wear on expensive valve assemblies.
Comprehensive Load Diagnostics: The module continuously monitors the health of the output loops. It detects open circuits and short circuits in the field wiring and reports these faults immediately to the Tricon CPU, enabling proactive maintenance before a safety event occurs.

FAQs

Can I use the high-current 20-320 mA outputs for standard 4-20 mA devices?

Technically, the range is configurable, but the 20-320 mA channels are specifically optimized for devices requiring higher drive current, such as specialized hydraulic proportional valves. Always verify your device's impedance and current requirements before connection.
Is the 3806E compatible with older Triconex chassis?

The 3806E installs into standard Triconex TMR I/O racks. However, you must verify your Tricon CPU firmware and software version (TriStation 1131) to ensure the system supports the high-density mixed-output configuration.
What precautions should I take for long-distance wiring?

Due to the high-current capability of the 320 mA channels, ensure your cable gauge minimizes voltage drop. Use high-quality shielded twisted-pair cabling to prevent electromagnetic interference from affecting the 4-20 mA precision loops.
