Current-limiting termination (CLT) devices form a new series of intelligent protected terminations designed for digital-input modules and proximity-sensor interfaces used in factory, industrial, and building automation systems, and more particularly for programmable logic controllers.

Main features of our current limiters or CLT series:

  • Up to 8 protected integrated channels available
  • Up to 2 MHz data interface speeds, isolated or non-isolated, SPI available
  • 600 W overvoltage protection integrated
  • Highly-immune solutions such as those described in IEC 61000-4
  • Power dissipation halved for more integrated modules

The SCLT3-8BQ7 and CLT01-38SQ7 are new additions to the serialized 8-input termination circuit series – SCLT03 and CLT01 – and are housed in a QFN-48L package (7x7mm).  

The CLT03-1SC3 and CLT03-2Q3 are new digital input current limiters available in SOT23-8L and QFN-16L 4.0 x 2.0.
