TRICONEX HD-8311 High-Density Input/Output Module

• System Architecture: The 3201 model is part of a triply redundant architecture, offering fault tolerance and high availability. This triple modular redundancy (TMR) ensures continuous operation even in the event of hardware failures.
• Processor Capabilities: Equipped with powerful processors capable of executing complex control logic and diagnostics simultaneously across three channels to ensure reliable operation.
• Memory: Includes sufficient memory for storing application programs, historical data, and system parameters, supporting extensive configuration and logging capabilities.
• Communication Interfaces: Supports various communication protocols including Modbus, OPC, and proprietary interfaces, enabling seamless integration with distributed control systems (DCS) and other plant networks.

• Output and Signal Parameters
  • It has 4 common - return, DC - coupled output channels, with a 12 - bit resolution and an output accuracy of less than 0.25% of the full - scale range within the 4 - 20mA controlled current range.
  • The output current can reach an over - range of 0 - 22mA and also has a 0mA output capability, with a step function response time of less than 2ms.
  • The typical switch time when a channel fails is 1ms, and the maximum switch time does not exceed 3ms.
• Power and Loop Parameters
  • The nominal external loop power supply is 24V DC, and the maximum allowable voltage is 32V DC, with reverse voltage protection.
  • For a 300Ω load, the loop power supply needs to be over 16V DC with a minimum current of 1A; for an 800Ω load, the loop power supply must be over 28V DC with a minimum current of 1A.
  • It has continuous over - range protection against 36V DC and 0V DC, which effectively protects the internal circuitry from damage due to abnormal voltage.

• Technical Specifications
  • Electrical and Signal Parameters
    • It is equipped with 16 non-commoned independent output channels, with a nominal output voltage of 24 VDC and a voltage adaptation range of 22 - 45 VDC.
    • Each channel can carry a current of 2A, and the signal response time is less than 1ms, enabling rapid execution of control commands.
    • It adopts optical isolation technology, with a point-to-point isolation voltage of 1500 VDC, which can effectively prevent electrical interference between channels and external circuits.
  • Physical and Weight Parameters
    • Its dimensions are 49cm × 45.3cm × 6.8cm, and it is designed for 19-inch rack mounting, which is consistent with standard industrial control cabinet installation specifications.
    • The weight of the module is 3.65 kg, and its solid structure ensures stability during long-term operation.
  • Environmental Parameters
    • The operating temperature range is -40°C to 85°C, which allows it to adapt to the extreme temperature fluctuations of various outdoor and indoor industrial sites.
    • It can work normally in an environment with a relative humidity of 0% - 95% (non-condensing), resisting the impact of humid air on internal components.
