  • Number of Output Channels: The number of independent output channels the module provides to control separate safety devices (often 1 or 2 channels).
  • Output Current Rating: The maximum current the module’s SSR can handle safely without overheating or damage. This rating should be compatible with the current requirements of the connected safety devices.
  • Output Voltage Rating: The voltage rating of the SSR, which should match the voltage of the devices being controlled.

Description

The TRICONEX TRICON 5451 is likely a Solid-State Relay Output TriPak designed for use within the Triconex Safety Instrumented System (SIS) manufactured by Invensys (now Schneider Electric). It plays a critical role in safety-critical applications by providing controlled electrical current to external actuators or safety devices based on digital commands from the SIS processor module.

There are two main possibilities for the TRICONEX TRICON 5451:

Possibility 1: Direct Triconex Product (Less Likely)

  • Product Name: TRICONEX TRICON 5451 Solid-State Relay Output TriPak
  • Product Description: If a genuine Triconex product, the 5451 would be a solid-state relay output module specifically designed for safe and reliable operation within safety instrumented systems. Solid-state relays offer advantages over traditional mechanical relays, such as faster switching speeds, longer lifespans, and reduced arcing.
  •  

Product Functionality (if a Triconex Product):

  • Digital Signal Reception: The module receives digital control signals from the SIS processor module, representing commands to activate or deactivate connected safety devices.
  • Solid-State Relay (SSR): The core component is the SSR, which acts as an electronically controlled switch. When a digital “ON” signal is received, the SSR allows electrical current to flow to the connected device (e.g., solenoid valve). Conversely, a digital “OFF” signal stops the current flow, deactivating the device.
  • Isolation: The module might have galvanic isolation between the internal control circuitry and the output side with the SSR. This isolation helps prevent electrical faults from affecting the SIS operation and ensures the integrity of the safety control loop.
  • Safety Integrity: A genuine Triconex product would likely adhere to strict safety standards (e.g., IEC 61508) for dependable operation in safety-critical applications.

Possibility 2: Compatible Module from Third-Party Supplier (More Likely)

A more probable scenario is that the TRICONEX TRICON 5451 might be a compatible solid-state relay output module from a third-party supplier designed to work with Triconex SIS. An example could be the Trident 5451 Solid-State Relay Output TriPak from Moore Automation Limited.

Finding More Information:

Due to the potential age of this product and the acquisition of Invensys by Schneider Electric, readily available information on the TRICONEX TRICON 5451 might be limited, especially if it’s a third-party module. Here are some ways to find more details:

  • Schneider Electric Website: Search for “TRICONEX TRICON 5451” or “Triconex solid-state relay output module” on the Schneider Electric website (https://www.se.com/us/en/) for product information or resources mentioning compatible modules.
  • Legacy Triconex Resources: Search for older Invensys Triconex user manuals or datasheets online. Automation parts suppliers or industrial automation forums might have archived resources for discontinued products.
  • Third-Party Supplier Websites: If the 5451 is a compatible module, searching for the model number on automation parts supplier websites (e.g., Moore Automation Limited) might reveal information about its functionalities and specifications.
