Designed for the most critical controlprograms, supervised digital output(SDO) modules meet the needs ofsystems whose outputs remain in asingle state for extended periods of time(in some applications, for years). AnSDO module receives output signalsfrom the main processors on each ofthree channels. Each set of three signalsis then voted upon by a fully faulttolerant quadruplicated output switchwhose elements are power transistors,so that one voted output signal is passedto the field termination.

Each SDO module has voltage andcurrent loopback circuitry coupled withsophisticated online diagnostics thatverify the operation of each outputswitch, the field circuit and the presence of a load. This design providescomplete fault coverage without theneed to influence the output signal.

The 3624 TRICONEX Digital Output Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 3624 implements Triple Modular Redundancy (TMR) at the module level. Each of the three independent channels receives digital output commands from the three Tricon Main Processors over the triplicated I/O bus. The channel outputs are then voted by quadruplicated power transistor circuitry to produce a single, highly reliable output signal to the field device. This architecture ensures that a fault in any single channel—whether due to processor failure, wiring error, or power transistor degradation—cannot cause either a dangerous failure-to-energize or a spurious trip that would disrupt process operation. The quadruplicated voter provides multiple redundancy for all critical signal paths, achieving IEC 61508 SIL 3 capability for safety instrumented functions.

Online Replacement: The 3624 allows for module replacement while the controller remains online. Field wiring is wired directly to an external Termination Panel (ETP) or Field Termination Assembly (FTA), not to the module itself.
Inserting the Module: Align the 3624 with the chassis guides and carefully slide it into the slot.
Securing: Push the module firmly into the backplane connector until it is fully seated. Tighten the captive screws on the top and bottom of the front plate to secure it to the chassis.

FAQs

  • What is the 3624?

    +
    The Triconex 3624 is a 24 VDC Supervised Digital Output (SDO) module designed for high-integrity Safety Instrumented Systems (SIS).
  • What is the primary purpose of the 3624 module?

    +
    The 3624 is used in critical environments (such as oil and gas, chemical processing, and power plants) to safely send output signals to field devices.
  • Does the module self-protect in case of an issue?

    +
    Yes. The 3624 features self-protection mechanisms and point isolation up to 1,500 VDC to prevent damage to the broader Tricon system in the event of a field fault.
  • What are the primary electrical specifications of the module?

    +
    The module operates at a nominal voltage of 24 VDC within an acceptable range of 16 to 30 VDC (36 VDC absolute maximum)
