Ics Triplex T9402 AADvance Trusted Digital Input Module

Description

• • Physical and Environmental Parameters
    • Size and Weight: The module has a compact structure, with a weight of 340 grams. Its common dimension specifications are 80mm × 130mm × 40mm, which is convenient for installation in standard chassis slots.
    • Environmental Adaptability: It can work normally in the temperature range of -20°C to 60°C, and the applicable humidity range is 5% to 95%. The IP65 protection level enables it to resist dust and water intrusion and adapt to the harsh working conditions of industrial sites.
  • Communication Parameters
    • Communication Capability: It supports mainstream industrial communication protocols such as Modbus TCP/IP and Modbus RTU. It is also equipped with communication interfaces including RS – 232 and RS – 485, which can realize seamless data interaction with AADvance controllers and other automation systems.
• Function Features
  • Multi-configuration Adaptability: It is compatible with simplex, dual and triple modular configurations. Users can select the appropriate configuration mode according to the safety and reliability requirements of different industrial control systems, which greatly improves the flexibility of the module in practical applications.
  • Efficient Signal Collection: With short scan times under various configurations, it can quickly capture the state changes of on-site digital devices. This high-speed signal collection capability ensures that the upper controller can obtain real-time on-site information and lay a foundation for timely and accurate execution of safety control strategies.
  • Strong Anti-interference Ability: The fully isolated design between channels and the high-voltage isolation performance can effectively block electrical interference between different signals and external electrical interference in industrial environments. It ensures the stability and accuracy of the collected signals and prevents misoperation of the control system caused by interference signals.
  • Easy Installation and Maintenance: It is designed for easy installation and is equipped with all necessary mounting hardware. It can be directly installed in standard chassis slots without complex auxiliary tools. Its compact size saves installation space in the control cabinet, and the clear interface design also facilitates later inspection and maintenance.
  • Comprehensive Fault Monitoring: It has a built-in sequence of events recording function and online fault detection and alarm functions. When a channel signal collection fails or there is an abnormal electrical parameter, it can send an alarm signal in time. This helps maintenance personnel quickly locate the fault point and shorten the maintenance time.
• Application Scenarios
  • Petrochemical Industry: It is widely used in the emergency shutdown systems of refineries and the fire and gas systems of chemical plants. In refineries, it monitors the status of pressure switches and liquid level sensors, and triggers the action of emergency shut-off valves when abnormal parameters are detected. In chemical plants, it collects signals from smoke detectors and links with the sprinkler system to suppress fire in time.
  • Power Energy Industry: It plays an important role in the reactor protection systems of nuclear power plants and the boiler protection systems of thermal power plants. In nuclear power plants, it monitors emergency stop buttons and steam turbine overspeed switches, and ensures the reliable execution of protection logic through triple redundancy. In thermal power plants, it collects water level switch signals to prevent boiler dry burning accidents.
  • Metallurgical Industry: It is applied to the blast furnace control systems of iron and steel plants. It connects vibration sensors and material level switches to realize real-time monitoring of the blast furnace body state. It can promptly feedback abnormal vibration of the furnace body and abnormal material level to the control system, so as to adjust the production process in time and avoid equipment damage caused by abnormal operation.
  • Mining Industry: It is integrated into the safety systems of mine mechanical hoists. It monitors the signals of limit switches on the hoists. When the hoist is overloaded or runs beyond the safe stroke, it can immediately send a signal to the control system to stop the hoist operation, thus preventing safety accidents such as hoist falling and equipment damage.
