The SCLT3-8BT8 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.

  • 8-input circuit in common ground low side topology
  • Wide range input DC voltage VI: -30 V to 35 V
  • On state threshold: < 11 V with RI= 2.2 kO
  • Off state threshold: Iin> 1.5 mA or Vi> 5 V
  • Protected against -30 V reverse polarity
  • 2.35 mA active current limiter with 10% tolerance
  • Drastic dissipation reduction:78 mW max. per input
  • Input digital filter with adjustable delay:20 µs to 3 ms
  • Energy-less LED visual status driver
  • Input logic state transfer through a 2 MHz SPI
  • Programmable 8 / 16-bit register length
  • Multi SCLT connection in daisy chain
  • Chip temperature OTA and under voltage UVA alarms
  • Multi parity bits and power loss detection with stop bits
  • Drastic reduction of isolated coupler count and I/O of the field bus ASIC
  • Power supply and input protection, RI= 2.2 kO:
  • IEC 61000-4-4 transient burst:
