Sales Briefcase
  • The SCLT3 series provides an 8-line protected digital input termination with serialized state transfer.

    This device enhances the I/O module density by cutting the dissipation (78 mW per input) and reducing the count of opto-transistors.
    An adjustable digital filter and an LED driver are embedded in each type 3 input section. Its 2 MHz SPI peripheral output serializes the input state transfer to the I/O module controller.

    Key Features

    • 8 inputs - 8-bit SPI output
    • High side input with common ground
    • 5 V voltage regulator
    • Package: QFN 7x7 - 48L or HTSSOP-38
    • 35 V reverse polarity capable
    • Adjustable current limiters
    • LED output for visual status
    • Optional: 16-bit mode with parity check, temperature and voltage alarms
    • Daisy chain capable
    • Input digital filter with adjustable delay: 20 µs to 3 ms
    • Power dissipation: 78 mW per channel
