Overview Manuals Applications Monitoring & Control Safety & Compliance Configuration

Features:

  • Triple Modular Redundant (TMR) architecture executes 2-out-of-3 hardware voting to eliminate single points of failure.
  • Provides 8 high-performance output channels, including six 4–20 mA outputs and two high-current 20–320 mA outputs.
  • Integrated online hot-spare support allows module replacement without operational shutdown or field wiring disruption.
The Triconex 3806E is currently supplied in brand-new, factory-sealed surplus or fully tested refurbished condition, complete with original manufacturer hardware keying and light green color identification plate.

Engineered specifically for critical industrial processes, this module provides highly reliable analog control output signals for heavy-duty actuators, specialized control valves, and turbomachinery protection systems.

Proper installation requires pairing the module with a dedicated Basic Termination Panel (Part # 9863-710) and supplying dual redundant +24 VDC external loop power to ensure compliant high-current output drive capability.

The Triconex 3806E High Current Analog Output Module is fully supported by the manufacturer (OEM).

  • Critical industrial turbomachinery valve and governor control.
  • Heavy-duty hydraulic and pneumatic positioner actuator driving.
  • Safety-critical process plant shutdown and analog regulating systems.
  • Monitors actual field current continuously via hardware loopback to verify commanded output state.
  • Detects open-loop conditions instantly on field connections without interrupting parallel channel drive.
  • Reports individual channel health and field loop status directly to Main Processors in real time.
  • Designed to meet SIL 3 functional safety requirement standards in Tricon safety instrumented systems.
  • Provides complete electrical channel-to-channel and channel-to-bus isolation to prevent fault propagation.
  • Complies with strict industrial EMC and environmental immunity standards for high-reliability applications.
  • Configured via TriStation 1130 software suite for precise channel range setup and threshold parametering.
  • Supports automatic module identification and software version verification upon chassis insertion.
  • Allows channel-by-channel output range assignment and dynamic trip limit parameter configuration.
Description
Triconex 3806E High Current Analog Output Module executes triplicated command voting to deliver highly reliable control signals in critical process automation and turbomachinery environments. The module isolates faulty processing legs internally while preserving continuous output continuity to field devices, preventing unselected internal paths from affecting operational field signals.

Featuring eight dedicated output points, the Triconex 3806E integrates six standard 4–20 mA channels and two high-current 20–320 mA channels specifically designed to drive heavy-duty industrial actuators and specialized valves. Built-in current loopback monitoring continually verifies output signal integrity independently of channel selection or connected load status.

Designed for high availability, the Triconex 3806E supports online hot-spare module replacement without disrupting active field wiring or requiring system power-downs. Comprehensive status indicators continuously track loop power health, leg fault states, and open-loop conditions to simplify system maintenance and enhance site safety.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How does the Triconex 3806E handle an internal channel failure?
Upon detecting an internal channel fault, hardware voting deactivates the faulty channel in less than 10 ms typical while maintaining normal operation across remaining healthy channels.
What status LEDs are available on the front panel of the Triconex 3806E?
The Triconex 3806E front panel contains PASS, FAULT, ACTIVE, LOAD, PWR1, and PWR2 indicators to report power rail status, open loop detection, and module health.
Does the Triconex 3806E support hot-swapping during active operation?
Yes, the Triconex 3806E supports online hot-spare maintenance, allowing operators to replace faulty modules without shutting down system power or disconnecting field wiring.
Which termination panel must be used with the Triconex 3806E?
The Triconex 3806E connects to field wiring using a dedicated Basic Termination Panel under Part Number 9863-710.
Can a standard Triconex 3805E module replace a Triconex 3806E?
No, because the Triconex 3806E includes two high-current (20–320 mA) output channels and requires termination panel 9863-710, whereas the 3805E provides eight standard 4–20 mA outputs.
How can I request pricing or check stock availability for the Triconex 3806E?
Price quotes, current inventory details, and worldwide shipping options for the Triconex 3806E can be requested directly via Apter Power's online inquiry portal or email.
