产品概述

描述

The SCLT3 series is an octal industrial digital input IC which drastically reduces the power dissipation of the digital input modules. Its current-sinking inputs can be configured for Type 1, Type 2, or Type 3 inputs as per IEC 61131-2 with few external components.

The SCLT3 series includes a serial interface which translates, conditions and serializes the data to CMOS-compatible signals through SPI. Combining its daisy-chaining capability with its accurate current limitation, the SCLT3 series enhances the I/O module’s density by cutting the power dissipation and reducing the number of optocouplers.

The SCLT3 series can be evaluated thanks to the STEVAL-IFP030V1 evaluation board. For detailed application guidelines refer to AN2846.

  • 所有功能

    • Eight current-sinking digital inputs with serializer
    • Enables inputs to meet type 1, 2 and 3 characteristic of IEC 61131-2 standard
    • Adjustable and accurate input current limitation for low power and heat dissipation:
      • 2.35 mA typ for Type 1 and Type 3
    • Integrated glitch and debounce filter with selectable delay time: 20 µs to 3 ms for EMC robustness
    • 35 V reverse polarity capable
    • SPI-Compatible Serial Interface 8-bit
      • Optional 16-bit mode with parity check, and diagnostics (temperature alarm, voltage alarms)
    • Daisy-Chain SPI to reduce isolation channels
    • 5 V voltage regulator
    • Energyless Field-Side LED drivers for visual status indication
    • Operating ambient temperature range from -40 °C to 105 °C
    • Packages
      • HTSSOP-38 – 500 µm pitch
      • QFN-48L – 500 µm pitch
    • Complies with the following standards:
