Overview Manuals Specifications Application Diagnostics & Protection Installation

Features:

  • It is the certified central processing unit (CPU) for executing safety instrumented functions (SIFs) up to SIL 3, making it suitable for high-risk applications.
  • It contains three independent processors operating in parallel with 2oo3 voting, ensuring high system availability and fault tolerance without spurious trips.
  • Supports Modbus TCP/Serial and OPC for plant-wide integration. Provides front-panel LEDs and optional web-based tools for real-time system health and fault diagnostics.
In a chemical plant, a reactor's Emergency Shutdown (ESD) system must bring the process to a safe state when a dangerous condition is detected. The 8300A is the certified brain of this system. Unlike a standard PLC, it is specifically designed and certified to meet the rigorous demands of IEC 61508 SIL 3 . This certification means it has been proven to have an extremely low probability of dangerous failure (PFDavg).

A single processor failure in a safety system could have two dangerous outcomes: failing to trip when needed (silent failure) or tripping when it should not (spurious trip). The 8300A solves this with TMR. It has three independent processors voting on the output. For a shutdown to occur, two out of three must agree . If one processor fails (computes the wrong output), it is outvoted, and the system continues to operate safely.

Integrating a safety system (SIS) with a basic process control system (BPCS/DCS) is essential for operational awareness. The 8300A supports Modbus TCP and OPC , allowing it to stream real-time safety status data to a plant's main SCADA system or distributed control system (DCS) . This allows operators to see the health of safety loops (e.g., "ESD Valve is in normal position") from the main control room.

The 8300A Triconex Power Supply Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL)by the manufacturer (OEM).

  • Manufacturer Triconex
  • Model 8300A
  • Condition New Original ready stock
  • Product Family 3664,4119A,3604E
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.
  • Oil & Gas: Emergency Shutdown (ESD) and Fire & Gas (F&G) systems on offshore platforms and refineries.
  • Petrochemical: Critical process interlocks and boiler burner management systems (BMS).
  • Power Generation: Turbine trip protection and control loops in nuclear or thermal power plants.
  • Dual Redundant Inputs: Connects to independent power grids (e.g., 120V AC/DC) to guarantee seamless failover without interrupting the system chassis.
  • Fault Isolation: Prevents internal component short-circuits from propagating or damaging the main backplane or adjoining I/O and processor modules.
  • Continuous Self-Diagnostics: Monitors input line voltage, output levels, internal temperature, and overcurrent conditions in real-time.
  • Hot-Swapping: Supports true online hot-swapping. A faulty module can be pulled and replaced live under dual-power setups without disrupting the production process.
  • Slot Keying: Employs mechanical keying pins on the Tricon chassis backplane to ensure it can only seat into its designated power slot, protecting against accidental misinsertion.
  • Compatibility Verification: When swapping legacy revisions or upgrading models, verify the hardware version against the TriStation 1131 configuration tool matrix to ensure proper system-firmware alignment.
  • Grounding & Wiring: Terminal connections must be torqued to specific factory specs. Ensure proper chassis grounding to suppress high-frequency electromagnetic interference (EMI).
Description
The Triconex 8300A is a Power Supply Module for the Trident Safety Instrumented System (SIS) from Schneider Electric's Triconex brand . As the central processing unit, it executes the safety logic for critical applications such as Emergency Shutdown (ESD), Fire & Gas (F&G), and Burner Management Systems (BMS) .

The 8300A leverages a Triple Modular Redundancy (TMR) architecture. It contains three isolated processors that execute the same safety program simultaneously. A hardware-based majority voting (2oo3) system ensures that a single processor failure does not compromise system safety or cause a process shutdown .

The 8300A communicates with I/O modules (e.g., digital inputs for ESD devices) via the Trident I/O bus. It supports extensive communication for integration with DCS and SCADA systems, including Modbus TCP, Modbus Serial, and OPC . An optional built-in webserver is also available for remote diagnostics and monitoring .

For legacy system maintenance, the 8300A is a critical spare part for Trident systems. It is a discontinued product, succeeded by newer Triconex solutions . The 8300A occupies a specific slot in a Trident chassis; it cannot be mixed with other processor types . Always verify module health via its front-panel STATUS and ACTIVE LEDs after installation .

Technical notes
The 8300A is meant for a specific, safety-critical operating system (Trident firmware). It cannot be programmed with standard PLC logic (IEC 61131-3) directly; it requires Triconex engineering software (Trident Configuration Tool).

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.
What is the safety rating of the 8300A?
The 8300A is certified for IEC 61508 SIL 3 . Its TMR architecture ensures that the failure of a single processor does not affect the safety function, maintaining a valid SIL 3 rating for the entire loop .
What diagnostics are available on the 8300A?
The module has a clear front-panel for status monitoring. A green STATUS LED indicates normal operation. The ACTIVE LED shows which processor (A, B, or C) is currently in control (In Command) . The built-in webserver (optional) provides detailed diagnostics remotely.
How does the 8300A achieve high availability?
The 8300A uses TMR (Triple Modular Redundancy) . It contains three processors (A, B, C) running in parallel. If one of the internal processors fails, the system detects the mismatch and continues to run safely using the other two, allowing for hot repair without shutting down the process .
