Triconex 5351 Discrete Input Module

Technical Specifications:

• It is designed for high availability and fault tolerance, ensuring continuous operation even in the event of hardware failures.
• The system supports safety integrity levels up to SIL 3 according to IEC 61508, making it suitable for critical safety applications.
• It operates with a triple modular redundant (TMR) architecture where three independent systems process data simultaneously and compare results to ensure accuracy and reliability.

• Processor and Memory Parameters
  • It is equipped with a 32-bit Motorola MPC860 processor running at a clock speed of 50 MHz, which supports real-time operating systems and efficiently executes complex control logic.
  • It is configured with 16 MB of non - battery backed DRAM, 32 KB of battery backed SRAM, and 6 MB of flash PROM, which can store a large number of control programs and real-time operation data stably.
• Communication Parameters
  • It uses the TriBus communication bus with a data transmission rate of 25 Mbps. The bus is equipped with 32-bit CRC protection and 32-bit DMA, and the communication part is fully isolated to ensure secure and stable data transmission.
  • It supports multiple communication protocols such as Modbus, Modbus TCP/IP, and Ethernet/IP, and is also compatible with communication interfaces like RS - 232/422/485 to achieve seamless connection with various industrial devices and systems.

• 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 opto - isolated, non - commoned digital output channels. The nominal output voltage is 115 VAC, with a voltage range of 80 - 155 VAC and a frequency range of 47 - 63 Hz.
    • The relay rating of the module reaches 5 A at 250 VAC or 30 VDC, and the signal response time is no more than 2 ms, which can realize rapid execution of control commands.
  • Physical and Weight Parameters
    • The shell is made of aluminum alloy, with dimensions of 200mm × 150mm × 50mm and a weight of 2 kilograms, which is convenient for installation in standard industrial control cabinets.
  • Environmental Parameters
    • The operating temperature range is - 40 °C to 70 °C, and the storage temperature can reach - 40 °C to 85 °C. It can operate normally in an environment with a relative humidity of 0% - 95% (non - condensing).
    • It has an IP65 environmental protection rating, which can effectively prevent dust and water from entering the module and ensure stable operation in humid and dusty industrial environments.
