The ICS Triplex T9402 is a digital input module that is part of the AADvance safety controller system, designed for high-reliability industrial control and safety-critical applications. Here are the detailed contents:
- Manufacturer: ICS Triplex (now part of Rockwell Automation)
- Part Number: T9402
- Product Type: Digital Input Module
- Country of Origin: USA
- Dimensions: Approximately 110 mm × 180 mm × 45 mm
- Weight: Approximately 0.5 kg
- Input Voltage: 24VDC
- Input Current: 2 mA per input
- Input Impedance: Greater than 2 kΩ
- Input Channels: 16 isolated digital input channels
- Channel Configuration: Each channel can be configured as normally open (NO) or normally closed (NC)
- Signal Acquisition: Reads digital signals from field devices such as limit switches and proximity sensors
- Data Output: Each channel provides both digital state and analogue voltage data to the processor module for field device state, line monitoring and field fault detection
- Communication Interface: Supports RS - 485 communication for Modbus RTU slave communications, and also communicates with the controller through the backplane bus (e.g., Genius Bus protocol with an update rate of 4 ms)triconex1.com
- Diagnostic Function: Has comprehensive automatic diagnostic and self - test functions. It provides local module and channel status indications through front - panel LEDs, and can detect faults in the module itself and external connections
- Redundancy: Adopts a triple - modular redundancy (TMR) architecture. It has three independent channels, each of which samples and processes independently. Voting logic is used to determine the output value of each channel, ensuring the correct output value even if one or two channels fail
- Operating Temperature Range: - 40°C to 70°C
- Humidity Range: 5% to 95% non - condensing
- Vibration Resistance: 0.5 g rms, 5 to 35 Hz
- Shock Resistance: 15 g, 11 ms half - sine pulse
- Certifications: Meets relevant industrial safety standards, such as CE, UL, etc. (specific certifications may vary depending on the application configuration)triconex1.com
- Industrial Automation: Used for monitoring and controlling various industrial processes, such as in manufacturing production lines
- Process Control: Suitable for applications in the petrochemical industry, power plants, and metallurgy industry, etc., to accurately acquire digital signals from field devices and ensure the safe and stable operation of the production process
- Safety - Critical Systems: Can be used to build safety - critical systems, providing high - reliability digital input signal acquisition capabilities under various conditions
