CLT03-2Q3 - Self powered digital input current limiter

Description

The CLT03 series is a digital input current limiter which drastically reduces the power dissipation of the digital inputs.

It does not require external power supply as the device is activated with the input signal and it consumes no power in off state.

Features

  • Single and dual isolated channel devices.
  • No power supply needed.
  • Digital input current limitation.
  • Enables input to meet type 1 and 3 characteristic of IEC 61131-2 standard.
  • Deglitch filter for EMC robustness.
  • High side / Low side compatible.
  • Inputs are reverse plugin compatible.
  • Drive isolated opto-couplers or non-isolated LVTTL digital input termination.
  • Operating ambient temperature range from -30 °C to 125 °C.
