Triconex 5301 Digital Input TriPak 1

Description

• • Environmental Parameters
    • Operating Temperature: It can operate stably in the temperature range of -40°C to 70°C, which can adapt to extreme temperature environments such as cold outdoor industrial areas and high – temperature chemical workshops.
    • Humidity Adaptability: The allowable relative humidity range during operation is 5% to 95% without condensation, which can cope with the humid working conditions of coastal oil and gas platforms and water treatment plants.
    • Safety Certification: It complies with the IEC61508:2010 international standard and has passed SIL3 certification, which confirms its high safety performance in critical control applications.
• Functional Features
  • Triple Redundant Signal Processing: The three internal sub – circuits can asynchronously detect and process the signals of the input terminals. Each sub – circuit is equipped with an 8 – bit microprocessor to communicate with the corresponding main processor. The system conducts voting on the signals processed by the three sub – circuits, which completely avoids the impact of single – circuit faults on signal accuracy and ensures the reliability of input signals.
  • Independent Circuit Isolation Protection: The three sub – circuits inside the module are in a fully isolated state. A fault occurring in one sub – circuit will not spread to the other two. This design maximizes the fault tolerance of the module and ensures that the module can still maintain normal signal collection functions when a local fault occurs.
  • Stuck – On State Detection: It has a dedicated self – testing function for the “ON stuck” state of signals. During the test, it inputs a closing signal to make the photoelectric isolation circuit read a zero input value, so as to detect whether the signal loop is stuck in the ON state. It freezes the last valid data during the test to ensure that the control system can still obtain stable data during the self – test.
  • Hot – Swappable Maintenance: It supports hot – swap operation. Maintenance personnel can install or replace the module online without shutting down the entire Triconex control system or disturbing the on – site wiring. This greatly shortens the maintenance time and reduces the impact of maintenance work on industrial production.
• Application Scenarios
  • Oil and Gas Production: It is installed in the safety control system of offshore drilling platforms and onshore oil fields. It collects digital signals from sensors such as pressure switches and temperature sensors on the drilling equipment, and transmits them to the Triconex controller to support the emergency shutdown system and fire and gas monitoring system in making timely responses.
  • Petrochemical Processing: It is integrated into the control system of petrochemical refining equipment and chemical reactors. It collects digital signals from on – site equipment such as valve position sensors and flow switches, providing accurate input data for the stable operation of the refining process and ensuring the safety of high – temperature and high – pressure reaction links.
  • Power Generation Industry: It is applied to the control system of thermal power plants and nuclear power auxiliary equipment. It collects digital signals from generator set auxiliary equipment, boiler combustion monitoring sensors and other devices, and cooperates with the Triconex system to realize real – time monitoring of power generation equipment and ensure the stable operation of the power grid.
  • Water Treatment Industry: It is deployed in the automatic control system of sewage treatment plants and water supply facilities. It collects digital signals from water level sensors, flow control switches and other equipment in the water treatment process, providing data support for the start and stop control of pumps, valves and other equipment in the water treatment process.
  • Non – Ferrous Metal Smelting: It is used in the control system of aluminum smelting and non – ferrous metal processing equipment. It collects digital signals from smelting furnace temperature detection switches, conveyor belt operation state sensors and other devices, ensuring the safe and stable operation of high – temperature smelting and material conveying processes.
