Features:

  • 16, non-commonede
  • TMR Digital Output Module
  • Voltage Loopback Diagnostic Circuit
  • Triple Modular Redundancy (TMR) Architecture
The TRICONEX 3604E is a 16-point, 24 VDC Digital Output (DO) module for the Tricon high-integrity, fault-tolerant control system. It is commonly used in Safety Instrumented Systems (SIS) for critical applications like Emergency Shutdown (ESD), Burner Management Systems (BMS), and High-Integrity Pressure Protection Systems (HIPPS).

A TMR digital output (DO) modulereceives output signals from the mainprocessors on each of three channels.Each set of three signals is then votedby special quadruplicated outputcircuitry on the module. The circuitryproduces one voted output signal andpasses it to the field termination. Thequadruplicated voter circuitry providesmultiple redundancy for all criticalsignal paths, guaranteeing safety andmaximum availability.

Each TMR digital output module has avoltage-loopback circuit which verifiesthe operation of each output switchindependently of the presence of a loadand determines whether latent faults exist. Failure of the detected fieldvoltage to match the commanded stateof the output point activates theLOAD/FUSE alarm indicator.

The 3604E TRICONEX 16-point, 24 VDC Digital Output (DO) module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
TRICONEX 3604E 16-point, 24 VDC Digital Output (DO) module Manuals, Datasheets, Drivers, Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
In addition, ongoing diagnostics areperformed on each channel and circuitof a TMR digital output module.Failure of any diagnostic on anychannel activates the Fault indicator,which in turn activates the chassisalarm signal. The Fault indicatormerely indicates a channel fault, not amodule failure. The module is guaranteed to operate properly in the presenceof a single fault and may continue tooperate properly with certain kinds ofmultiple faults.
All TMR digital output modulessupport hot-spare capability, andrequire a separate external terminationpanel (ETP) with a cable interface tothe Tricon backplane. Each module ismechanically keyed to preventimproper installation in a configuredchassis.
Digital outputs are designed to sourcethe current to field devices, so fieldpower must be wired to each outputpoint on the field termination.
  • Emergency Shutdown Systems (ESD):Drives solenoids/valves/trip relays for safe shutdown
  • Burner Management Systems (BMS):Safe sequencing, ignition interlocks & purging for boilers/furnaces
  • High-Integrity Pressure Protection Systems (HIPPS):Fast, reliable outputs to isolate high-pressure sources
  • Fire & Gas (F&G) Systems:Controls dampers, beacons, sirens & deluge valves
  • Process Shutdown and Equipment Interlocks:Manages motors, contactors & critical valves in high-demand environments
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Mounting: The 3604E must be installed in a standard Tricon chassis, typically in a 19-inch rack.
Termination: Field wiring connects via an External Terminal Panel (ETP).
Keying: Ensure mechanical keys on the chassis match the module to prevent insertion into the wrong slot.
Field Power: 24 VDC is required. A voltage loopback circuit on the module verifies operation. 

FAQs

  • What is the Triconex 3604E?

    +
    The Triconex 3604E is a 24 VDC, 16-point Digital Output (DO) module designed for high-availability Triple Modular Redundant (TMR) systems. It is widely used in safety-critical industrial environments like refineries and power plants
  • What diagnostic features does it have?
