Triconex 4139 Triple Redundant Digital Input Module

Description

• • Electrical and Physical Parameters
    • Isolation Performance: There is 500V DC galvanic isolation between channels and between channels and the backplane, which effectively prevents signal crosstalk and external electrical interference.
    • Power Consumption: The typical operating power consumption is 6W, and the low power consumption design reduces the overall energy load of the safety control system.
    • Physical Dimensions: The module adopts a standard rack-mounted size, with dimensions of 203mm×127mm×51mm, which is suitable for installation in Triconex standard control cabinets.
    • Weight: The net weight is about 0.8kg, which is light and convenient for on-site installation and handling.
  • Environmental Parameters
    • Operating Temperature: It can operate stably in the temperature range of -20°C to 60°C, adapting to the temperature changes of indoor and outdoor industrial sites.
    • Storage Temperature: It can be safely stored in the environment of -40°C to 85°C, which meets the requirements of long-distance transportation and long-term storage.
    • Humidity Adaptability: It can work normally under the condition of relative humidity of 5% – 95% without condensation, which is applicable to high-humidity industrial environments such as chemical plants and coastal oilfields.
• Functional Features
  • Triple Modular Redundancy for High Reliability: It adopts triple modular redundancy architecture. The three independent circuit units simultaneously process the same input signal and vote on the results. Even if one unit fails, the other two units can ensure the normal output of signals, which eliminates single-point faults and ensures the reliability of the safety system.
  • Multi-channel Parallel Acquisition: With 16 independent input channels, it can collect digital signals from multiple field devices in parallel. This design reduces the number of modules required in the system, saves the installation space in the control cabinet, and simplifies the system wiring.
  • Built-in Fault Diagnostic Functions: The module is equipped with a full-range self-diagnostic system, which continuously monitors the operating status of each input channel, internal circuits, and the connection status with the controller. When a fault such as an open circuit or short circuit of the input line occurs, it will immediately send a fault alarm signal to the controller to facilitate timely troubleshooting.
  • Hot-swap Support for Uninterrupted Production: It supports hot-swap operation. When the module needs maintenance or replacement, it can be pulled out and installed again without stopping the operation of the entire safety control system, which minimizes the production downtime caused by equipment maintenance.
  • Strong Anti-interference Capability: The galvanic isolation design between channels and the special anti-interference circuit board layout can effectively suppress electromagnetic interference from frequency converters, motors, and other high-power equipment in the industrial field, ensuring the accuracy and stability of input signal collection.
• Application Scenarios
  • Oil and Gas Industry: It is widely used in oil drilling platforms, oil pipelines, and oil refineries. It collects signals from emergency stop buttons, pipeline pressure switches, and valve position limiters, and transmits them to the safety controller to realize the emergency shutdown and safety protection of the production process when abnormal conditions occur.
  • Chemical Industry: In chemical production workshops, it is used to collect state signals from equipment such as reaction kettle temperature switches, chemical liquid level sensors, and exhaust gas detection probes. It cooperates with the burner management system and emergency shutdown system to prevent safety accidents such as chemical leakage and explosion.
  • Power Generation Industry: It is deployed in thermal power plants, nuclear power plants, and other power facilities. It collects signals from generator set protection switches, high-voltage switchgear status sensors, and cooling system fault detectors. It provides data support for the stable operation of the power generation system and triggers protective measures in time when faults occur.
  • Marine and Offshore Engineering: It is installed in marine oil production platforms and ship power systems. It collects signals from marine equipment such as hull stability sensors, marine pump operation status switches, and navigation equipment safety sensors. It adapts to the harsh marine environment and ensures the safety of offshore production and ship navigation.
  • Pharmaceutical Manufacturing Industry: In the automated production lines of pharmaceuticals, it collects signals from the status switches of sterile production equipment, material feeding in-place detectors, and packaging line fault sensors. It ensures that each link of pharmaceutical production complies with safety and hygiene standards and avoids production accidents caused by equipment failure.
