Triconex DI3301 Digital Input Module

Description

• Environmental Parameters
  • The module is robust and durable, and its structural design can resist the vibration of industrial sites.
  • The DI3301 – E variant has intrinsic safety certification and can be directly used in hazardous areas without additional explosion – proof isolation equipment.
• Mechanical and Other Specifications
  • It adopts a rack – mounted design and is compatible with the 2301 – type backplane for typical application scenarios.
  • It has a mechanical locking structure to avoid improper installation in the configured backplane.
  • Its weight is 1.42 kilograms, which is light and convenient for installation and handling.

• Triple Modular Redundancy and Fault Tolerance
  • The triple modular redundancy architecture enables three independent channels to process signals simultaneously. Even if one channel breaks down, the other two channels can still ensure the normal transmission and processing of signals, avoiding the failure of the entire safety function.
  • It supports hot – swap. The module can be replaced online during system operation without shutting down the whole system, minimizing production downtime.
• Powerful Diagnostic Capabilities
  • It is equipped with forced – to – value diagnosis function, which can test the connectivity and status of input points in less than 2ms, and can effectively detect faults such as open circuits, short circuits, ground faults and sensor abnormalities of signal lines.
  • When a fault is detected, the fault indicator light will be turned on immediately and an alarm signal will be sent to the system to remind maintenance personnel to deal with the problem.
• Easy System Integration and Operation
  • It communicates with the Tricon CPU through the system’s dedicated PCI bus, featuring fast transmission speed and low delay, realizing real – time data exchange with the main controller.
  • It is equipped with LED indicator lights that can intuitively display the input status of each channel, as well as the module’s power supply, fault and communication status, enabling operators to grasp the operation situation at a glance.
• Strong Environmental Adaptability
  • The module is designed to cope with harsh industrial environments. Its structure and material selection can adapt to the temperature and humidity changes on industrial sites, ensuring long – term stable operation.
  • The high noise suppression capability and anti – electromagnetic interference design allow it to maintain accurate signal collection and transmission in complex electrical environments.

• Oil and Gas Industry
  • It is widely used in emergency shutdown systems of offshore drilling platforms. It collects signals from flame detectors, pressure switches and manual emergency stop buttons. When a dangerous signal is detected, it can quickly transmit the signal to the processor to trigger emergency measures such as cutting off fuel supply and closing valves.
  • It is deployed in long – distance oil and gas pipelines to collect status signals of pipeline emergency shut – off valves and leakage detectors, so as to promptly respond to pipeline anomalies and avoid environmental pollution and economic losses caused by oil and gas leakage.
• Chemical Industry
  • It is applied in ethylene cracking units. It collects signals from emergency stop buttons, toxic gas detectors and emergency drain valve limit switches around cracking furnaces, providing data support for the safe operation of the units and preventing safety accidents such as explosions caused by gas leakage.
  • It is used in hazardous chemical storage areas to connect with the status sensors of storage tank safety valves and fire door switches. Once an abnormal signal is detected, it can immediately feed back to the control system to start the corresponding safety protection procedures.
• Power Generation Industry
  • It is integrated into the safety control system of thermal power and nuclear power plants to collect status signals of generator set vibration sensors, temperature switches and emergency shutdown devices. It helps the control system monitor equipment operation in real time and avoid major equipment damage accidents.
  • It is used in the turbomachinery control system of power plants to monitor the operation status signals of turbomachinery and ensure that the turbomachinery operates within the safe parameter range.
• Other Industrial Fields
  • In the metallurgical industry, it is used in steelmaking blast furnace control systems to collect limit switch signals of various mechanical equipment and emergency alarm signals on the production line, ensuring the coordinated and safe operation of each production link.
  • In the water treatment industry, it is deployed in sewage treatment plants to collect digital signals from water pump start – stop status and electromagnetic valve switches, ensuring the stable operation of the water treatment process and the compliance of effluent quality.
